| * cwillu pokes | 08:58 | |
| cwillu | you're not rcn-ee :/ | 08:59 |
| hrw | if I want to change something in ubuntu kernel config for panda how to get .config in other way then cp /boot/config-*? | 10:50 |
| cwillu_at_work | hrw, that's the only way, unless /proc/config has been enabled in the kernel (which it hasn't in ubuntu afaik() | 10:51 |
| hrw | cwillu_at_work: "apt-get source linux-ti-omap4" gave me ubuntu source package but it uses split config | 10:52 |
| sebjan_ | hrw: to get the running defconfig, just run zcat /proc/config.gz | 12:39 |
| hrw | let me rephrase question: how to get kernel config from inside of linux-ti-omap4 source package? | 12:40 |
| sebjan_ | hrw: ok, sorry. the config shall be in a folder debian.ti-omap4/config/config.common.ubuntu. Do you have this file in the source package? | 12:42 |
| hrw | yep - but tahts all? | 12:45 |
| sebjan_ | hrw: yes, what did you expect? | 12:46 |
| hrw | preferred to be sure - split configs exists for a reason | 12:46 |
| sebjan_ | hrw: right, it is not used in this case, not sure why actually... | 12:47 |
| hrw | sebjan_: one flavour only | 12:48 |
| sebjan_ | yes, it makes sense... | 12:49 |
| ogra | hrw, so looking at your genesi f-k patch, it seems to expect that /boot is a vfat | 14:28 |
| ogra | that wont work | 14:28 |
| hrw | ogra: flash-kernel is set of hacks already | 14:49 |
| ogra | hrw, that doesnt solve the probelm that /boot cant be vfat :) | 14:49 |
| hrw | on smarttop it is ext2 by default | 14:49 |
| hrw | smartbook I mean | 14:50 |
| ogra | oh, that seems fine then, is it the same on smartbook ? | 14:50 |
| ogra | ah | 14:50 |
| hrw | markos_: does smarttop has /boot/ also on pata drive like it is in smartbook? | 14:50 |
| ogra | and does it use ext2 too ? | 14:51 |
| ogra | :) | 14:51 |
| markos_ | ogra: initially it used vfat but now with new uboot it's able to use ext2 as wel | 14:51 |
| markos_ | but yes | 14:51 |
| ogra | hrw, well, if its all ext2 then your patch seems fine to me | 14:52 |
| markos_ | it needs a uboot upgrade though | 14:53 |
| hrw | ogra: I would prefer rewrite of whole script but no devices to check does it works properly on all | 14:53 |
| markos_ | old smarttops will have to be upgraded first | 14:53 |
| ogra | hrw, i would prefer we split flash-kernel in functions and device spcific parts ... but i guess that needs wider discussion with debian-arm | 14:54 |
| hrw | yep | 14:54 |
| ogra | i.e. have a flash-kernel-common package that provides script snippets we can source | 14:54 |
| hrw | ogra: even flash-kernel can get rewrite properly | 14:55 |
| ogra | well, heh | 14:56 |
| ogra | f-k is somewhat constantly being rewritten | 14:56 |
| hrw | compare omap_flash_kernel and efikamx_flash_kernel functions | 14:56 |
| hrw | both have update_uImage_symlink() update_initrd_symlink() | 14:57 |
| ogra | hrw, well, theye functions come from NCommander for his generic update | 15:00 |
| ogra | which is very broken anyway | 15:00 |
| ogra | they neerd fixing all over | 15:01 |
| ogra | *need | 15:01 |
| hrw | I am a bit tired of rewriting update scripts again and again | 15:04 |
| hrw | few years ago I merged 5-6 zaurus update scripts into one | 15:04 |
| ogra | right | 15:04 |
| hrw | took year to get it tested on all supported devices and 2-3 developers more | 15:04 |
| ogra | what i want is device specific functions separate from HW specific ones | 15:04 |
| ogra | i.e. update NAND ... update u-boot_vfat separated from the omap or dove or whatever functions | 15:05 |
| hrw | it looks like omap and dove support was added by ubuntu | 15:06 |
| ogra | yes | 15:06 |
| ogra | omap was initially aded by me, dove comes from NCommander | 15:06 |
| ogra | both were completely redone when NCommander added the "improved subarch detection" stuff | 15:07 |
| hrw | style is completely different | 15:07 |
| ogra | yes | 15:07 |
| ogra | it was initally identical | 15:07 |
| ogra | but the spec was implemented in a way to use uname instead of /proc/cpuinfo | 15:07 |
| ogra | which breaks the style | 15:08 |
| === JaMa is now known as JaMa|Off | ||
| ogra | hrw, for that part you should discuss with NCommander | 15:10 |
| ogra | this change also introduces bugs for unsupported boards ... i.e. it makes it try to flash to NAND on blaze (where no nand exists) | 15:11 |
| hrw | how to get default set of kernel options for arm device in ubuntu? | 16:18 |
| ogra_ac | hrw, /boot/config-$(uname -r) | 16:22 |
| ogra_ac | for source config, ask the kernel team | 16:22 |
| rsalveti | don't know exactly how the kernel selects the default options for arm in general | 16:22 |
| hrw | k | 16:22 |
| rsalveti | but at the git repository you can already check what is common | 16:22 |
| rsalveti | http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-maverick.git;a=blob;f=debian.master/config/armel/config.common.armel;h=0f0e053b1780d9d67b9c0ac7d1051fabf3d176b8;hb=HEAD | 16:22 |
| rsalveti | for example | 16:22 |
| rsalveti | as the master repo has both omap and versatile | 16:22 |
| ogra_ac | well, the actual config is merged from nippets during package build iirc | 16:22 |
| rsalveti | yup | 16:22 |
| ogra_ac | *snippets | 16:22 |
| hrw | ok | 16:23 |
| hrw | thx | 16:23 |
| rsalveti | hrw: but the "default" options is something that maybe someone from the kernel team can help you | 16:23 |
| ogra_ac | easiest is really to just wget the binary and dpkg -x it i bet | 16:23 |
| hrw | ok | 16:23 |
| hrw | trying to make efikasb kernel to be more ubuntu like | 16:23 |
| ogra_ac | build a package ;) | 16:24 |
| hrw | already did | 16:24 |
| ogra_ac | ah, cool | 16:25 |
| rsalveti | there are also some extra ubuntu sauce generally applied at ubuntu's kernel | 16:25 |
| rsalveti | don't know if you wan to check those too | 16:25 |
| rsalveti | hrw: and which version are you building? the stock 2.6.31 kernel? | 16:25 |
| ogra_ac | you should add them if possible, often distro userspace features correspond to them | 16:25 |
| hrw | rsalveti: yes 2.6.31.14.6 | 16:26 |
| hrw | and do not plan to add ubuntu patches on top of it | 16:26 |
| * hrw is not kernel hacker | 16:26 | |
| cooloney | oh, are you guys talking about linaro kernel or ubuntu kernel? | 16:27 |
| ogra_ac | what i did for the ac100 kernel was to ssh into my panda that had a source tree, copy the config to .config and then run make menuconfig on both | 16:27 |
| hrw | none of those cooloney | 16:27 |
| cooloney | rsalveti: how's going, had a nice vacation? | 16:27 |
| cooloney | hrw: got this, man | 16:28 |
| ogra_ac | its very time consuming to do it that way but you will end up with modtly identical configs | 16:28 |
| ogra_ac | *mostly | 16:28 |
| rsalveti | cooloney: yup, very nice :-) | 16:28 |
| cooloney | rsalveti: great. man | 16:28 |
| * cooloney just read a news, Marvell release a qual-core ARM chip | 16:29 | |
| hrw | CONFIG_SCSI_MULTI_LUN is not set in TI-omap4... bad | 16:29 |
| rsalveti | cooloney: how was plumbers? | 16:29 |
| rsalveti | hrw: ti-omap4 unfortunately doesn't contain all arm common defines at the master repo | 16:30 |
| cooloney | http://www.marvell.com/company/news/press_detail.html?releaseID=1447 | 16:30 |
| cooloney | rsalveti: very good | 16:30 |
| cooloney | met several linux-omap folks and other ARM guys | 16:31 |
| hrw | rsalveti: extra fun is that efikas have usb-wifi which rt2800usb does not want to load firmware for (and same firmware works with staging driver) | 16:31 |
| rsalveti | cooloney: cool :-) | 16:31 |
| cooloney | hrw: what's CONFIG_SCSI_MULTI_LUN for? | 16:32 |
| rsalveti | hrw: haha :-) | 16:32 |
| cooloney | hrw: i guess it is for some multi volume USB disk? | 16:32 |
| hrw | cooloney: Prompt: Probe all LUNs on each SCSI device | 16:32 |
| hrw | cooloney: think: real multislot card readers for example | 16:32 |
| ogra_ac | does the efika have that ? | 16:33 |
| hrw | cooloney: and I have one of those | 16:33 |
| hrw | ogra_ac: I have such on usb | 16:33 |
| * GrueMaster drools over the marvel XP specs. | 16:33 | |
| ogra_ac | oh, that doesnt show as usb disks ? | 16:33 |
| ogra_ac | intresting | 16:33 |
| hrw | ogra_ac: without multi_lun only CF works. with: cf, sd, ms, xd | 16:35 |
| ogra_ac | well, then we should enable it asap | 16:35 |
| ogra_ac | file a bug ;) | 16:35 |
| hrw | ogra_ac: popular cheap multislot readers have one controler so one card at time. this one handle 4 cards at same time | 16:35 |
| cooloney | hrw: good point. could you please file a bug, then we can SRU a patch | 16:37 |

| rsalveti | ogra_ac: were you able to test the new qt packages? | 17:51 |
| ogra_ac | rsalveti, yes | 17:51 |
| rsalveti | and? | 17:51 |
| ogra_ac | Illegal instruction | 17:51 |
| ogra_ac | :( | 17:51 |
| ogra_ac | see the bug | 17:51 |
| ogra_ac | tiago also commented | 17:51 |
| rsalveti | oh, cool, too much emails at my inbox | 17:52 |
| ogra_ac | sadly it doesnt seem to work as expected | 17:53 |
| ogra_ac | tiagos test of just running the lib seems to show no misdetectin though | 17:53 |
| GrueMaster | Might be another failure point. | 17:55 |
| ogra_ac | i.e. i dont get the processor features line he mentions | 17:55 |
| ogra_ac | GrueMaster, well, its definitely NEON related given just building it with NEON disabled makes it all work fine | 17:55 |
| GrueMaster | What I mean is it may be code that is ouside the run-time detection. | 17:56 |
| rsalveti | ogra_ac: remember he's using qt 4.7.1 while posting at the bug | 17:57 |
| ogra_ac | rsalveti, yeah | 17:57 |
| rsalveti | maybe this processor features is not there for the version we're using | 17:57 |
| rsalveti | I don't get it even on panda | 17:57 |
| ogra_ac | yup | 17:57 |
| * ogra_ac hasnt set up his panda yet for cross checking | 17:58 | |
| GrueMaster | What's the bug number again? I can test the code on my dove to verify. | 17:58 |
| ogra_ac | i have barely unpacked my suitcase | 17:58 |
| rsalveti | bug 664431 | 17:58 |
| ubot2 | Launchpad bug 664431 in qt4-x11 (Ubuntu Natty) (and 2 other projects) "QT on armel is built with NEON by default (affects: 2) (dups: 1) (heat: 30)" [Undecided,New] https://launchpad.net/bugs/664431 | 17:58 |
| rsalveti | ogra_ac: does it also crashes while running QT_NO_NEON=1 mumble? | 18:01 |
| ogra_ac | yep | 18:01 |
| rsalveti | could be the case that the features thing is not working the way expected | 18:02 |
| ogra_ac | yes, i would expect so | 18:02 |
| rsalveti | I don't believe it was ever tested on a no-neon hardware | 18:02 |
| ogra_ac | to sad that slangasek already dropped the working packages | 18:02 |
| slangasek | "working"? those packages were sitting verification-failed for some time before I removed them | 18:03 |
| rsalveti | would be good to trace the error | 18:03 |
| ogra_ac | slangasek, huh ? who did set that ? | 18:03 |
| * ogra_ac checks the bug | 18:03 | |
| Jefro | hi all - if anyone has a second to help me get rcn-ee's scripts working for a beagleboard, I'd love a hand | 18:04 |
| ogra_ac | slangasek, now thats weird, while i see that pitti set it to failed i dont get why | 18:04 |
| slangasek | ogra_ac: because it was reported to regress on non-NEON systems | 18:04 |
| ogra_ac | Jefro, best is to wait for rcn-ee for that | 18:05 |
| ogra_ac | slangasek, err, no, exactly the opposite | 18:05 |
| ogra_ac | slangasek, it fixed it for non-NEON systems | 18:05 |
| slangasek | oh right; it was reported to regress on NEON systems | 18:05 |
| Jefro | ogra_ac - thanks | 18:05 |
| ogra_ac | which is nonsense | 18:05 |
| slangasek | <shrug> | 18:05 |
| ogra_ac | given we announce that no library in maverick will do NEON | 18:06 |
| ogra_ac | so it breaks a commitment | 18:06 |
| slangasek | no library in maverick will *require* NEON | 18:06 |
| ogra_ac | right | 18:06 |
| ogra_ac | given that QT in maverick can currently only be build with statically having NEON on or off my upload was a proper fix | 18:07 |
| ogra_ac | that upstream tried to add dynamic detection doesnt make the fix less valid | 18:07 |
| ogra_ac | until we have a dynamic fix in place at least | 18:09 |
| rsalveti | ogra_ac: I also believe it is a post release regression to just disable it at qt | 18:10 |
| rsalveti | I know we're saying we're building without neon by default | 18:10 |
| rsalveti | but would be strange for users to have qt running slower because of an update | 18:10 |
| ogra_ac | well | 18:10 |
| rsalveti | doesn't make sense to me | 18:10 |
| ogra_ac | talk to davidm | 18:10 |
| rsalveti | that's why I thought it would be better to just fix the run time detection | 18:11 |
| ogra_ac | i had a pretty strict request to switch it off immediately | 18:11 |
| rsalveti | ogra_ac: why? it's a ubuntu discussion in general, I understand the problems | 18:11 |
| ogra_ac | yes, i agree that runtime detection is a better fix, but if it doesnt work we have to fix it another way | 18:11 |
| rsalveti | sure, in case it doesn't work we just disable it | 18:12 |
| ogra_ac | and apparently the only way is static atm | 18:12 |
| rsalveti | but first let's try to get the proper fix in | 18:12 |
| ogra_ac | right | 18:12 |
| ogra_ac | but the "proper" fix seems ot require far more currently | 18:12 |
| ogra_ac | since just backporting from upstream doesnt seem to work | 18:12 |
| rsalveti | it seems, let's at least get the correct trace | 18:13 |
| rsalveti | and identify what's happening | 18:13 |
| rsalveti | don't think that will take a lot of time | 18:13 |
| ogra_ac | no | 18:13 |
| ogra_ac | what i'm concerned about it that i already drown in mail from people running QT apps on the ac100, that the working packages were removed from proposed is a bit disturbing | 18:14 |
| rsalveti | I know, but let's give at least one or two days to try to get the proper fix | 18:14 |
| ogra_ac | yes | 18:14 |
| rsalveti | now that you have the hardware and can try to trace the problem | 18:15 |
| rsalveti | if we're unable to fix, push the new packages without neon at all and we're fine | 18:15 |
| ogra_ac | right, though i wont do that tonight anymore ... i'm jetlagged and did get off a plane less than 24h ago | 18:15 |
| rsalveti | ogra_ac: sure, take your time | 18:16 |
| rsalveti | ogra_ac: go to sleep then :-) | 18:16 |
| ogra_ac | i would have tested during plumbers, but they dont have an elmo (read: the network there was so bad that most of us couldnt even get their mails) | 18:16 |
| rsalveti | yeah, elmo rocks | 18:17 |
| rsalveti | uds was perfect | 18:17 |
| ogra_ac | to early for bed yet ... need to stay up to get my schedule correct | 18:17 |
| ogra_ac | just thinking is a bit hard atm :) | 18:17 |
| rsalveti | :-) | 18:17 |
| ogra_ac | plumbers was depressing overall | 18:18 |
| rsalveti | ogra_ac: why? no interesting stuff to discuss this year? | 18:19 |
| ogra_ac | now that they are over upstart vs systemd they start bashing us for copyright assignment | 18:19 |
| rsalveti | haha, they will always find something to complain :-) | 18:20 |
| ogra_ac | well, there was intresting stuff but i didnt like the mood | 18:20 |
| ogra_ac | also seeing how lennart pulled strings to make all upstreams use systemd and Keybuk not being there at all to be able to stop that was annoying | 18:20 |
| ogra_ac | seems that many userspace things will defauolt to systemd in the near future | 18:20 |
| ogra_ac | i.e. gnome-session will go away | 18:21 |
| rsalveti | got it | 18:21 |
| ogra_ac | all in all it felt like a redhat/intel conference | 18:21 |
| ogra_ac | i felt very misplaced | 18:21 |
| rsalveti | but it was, somehow | 18:21 |
| ogra_ac | yes | 18:21 |
| ogra_ac | its just sad to see that so many important decisions are made there and that they are made with an anti ubuntu attitude in mind | 18:22 |

| GrueMaster | Haven't tried mumble. | 18:53 |
| GrueMaster | This is on my dove buildd (rack in basement). | 18:54 |
| rsalveti | should fail while loading mumble | 18:54 |
| ogra_ac | right | 18:54 |
| GrueMaster | Other system has been offline since Dallas. | 18:54 |
| ogra_ac | you should get a SIGILL | 18:54 |
| GrueMaster | I ran it according to the instructions in the bug, comment #30. Will find some test apps. | 18:55 |
| ogra_ac | comment 30 is useless with our version | 18:55 |
| ogra_ac | 8as you can see from the above discussion) | 18:55 |
| rsalveti | could -mfpu=neon optimize general fp code at the qt build? | 18:57 |
| rsalveti | then it'll fail for sure | 18:58 |
| GrueMaster | I may give my son some spare hw next time I see him. He knows a lot about QT. | 18:58 |
| ogra_ac | GrueMaster, just run mumble ;) | 18:58 |
| ogra_ac | thats a safe test | 18:58 |
| ogra_ac | no need to install a desktop for that, just use ssh -X user@dove mumble | 18:58 |
| GrueMaster | I can't. The system has a minimal install for building. No X. | 18:58 |
| GrueMaster | Still need to install for dependencies. | 18:59 |
| ogra_ac | use a chroot | 18:59 |
| ogra_ac | its not that it will take much time with a local mirror | 18:59 |
| GrueMaster | I'll unpack my A0 and get it running in a bit. | 18:59 |
| GrueMaster | It looks like it will take 64 minutes just to pull the PPA packages. | 19:00 |
| GrueMaster | They're not mirrored. | 19:00 |
| ogra_ac | ah | 19:00 |

| rcn-ee | Jefro, ping | 19:09 |
| Jefro | rcn-ee hey! thanks - I am having difficulty with the beagleboard script | 19:11 |
| rcn-ee | hey Jefro,which of the scripts are you haing issues with? is it doing something odd? | 19:11 |
| Jefro | ./setup_sdcard.sh gives me a syntax error | 19:11 |
| Jefro | ./setup_sdcard.sh: line 333: syntax error near unexpected token `>' | 19:12 |
| rcn-ee | that might be a bashism.. ;) | 19:12 |
| Jefro | it must be. the line has a " &>> " in it. | 19:12 |
| rcn-ee | is that the 'sd.log' part of the script? you can just comment that out, it's just to make it less noisy.. | 19:13 |
| Jefro | I succeeded in getting it to work by putting a space between & and >> but now I think I probably should have just taken out the & and put a 2&>1 at the end | 19:13 |
| Jefro | ah, ok - looking | 19:13 |
| Jefro | yes, that is the sd.log line | 19:13 |
| Jefro | the resulting image, however, fails to boot on my xM A2 | 19:14 |
| Jefro | well, it boots up to a certain point but then fails with 'no init' and leaves me at an (initrd) prompt | 19:14 |
| rcn-ee | yeah, just nuke the "&>> ${DIR}/sd.log" i'll come up with something else to work better with dash.. | 19:14 |
| rcn-ee | That's weird, what was your full "./setup..." line? | 19:15 |
| rcn-ee | (i have an A2 i test it on..) | 19:15 |
| Jefro | ./setup_sdcard.sh --mmc /dev/sdf --uboot beagle --use-default-user | 19:15 |
| Jefro | I'll try it again, just a sec (currently running rsalveti's preinstalled image) | 19:15 |
| rcn-ee | weird, that's perfect.... | 19:16 |
| rcn-ee | by chance is it 16/8g card? i've had some users report problems with that, but haven't been able to replicate it.. | 19:18 |
| Jefro | 4G Kingston card | 19:19 |
| Jefro | oops, no, that's the other one - this is a 4G no-name card | 19:19 |
| Jefro | I'll try it on the Kingston card | 19:20 |
| rcn-ee | another thing, if the script dies on error, it actually doesn't finish building the image.. | 19:21 |
| Jefro | it looked like it completed - running now on different card | 19:23 |
| Jefro | looks like it completed. the last line is "Formatting Boot Partition." | 19:24 |
| rcn-ee | that's not even close.. ;) | 19:24 |
| Jefro | hoo boy. is there a -v I can turn on? | 19:24 |
| Jefro | I'm running this on Ubuntu 8.10 BTW | 19:24 |
| Jefro | if that makes a dif | 19:24 |
| rcn-ee | not really, it's a pretty simple/stupid script.. ;) the last thing it really says "Populating rootfs Partition" | 19:25 |
| Jefro | ha... well, that may be why it only got as far as initrd! | 19:26 |
| rcn-ee | i'm suprised it got that far... if it died after building the first fatfs, there shouldn't have even been an uImage... | 19:26 |
| Jefro | it looks like it populated the boot partition | 19:27 |
| Jefro | this is for a "getting started" article, so I may go with rsalveti's premade script for now and point readers at the rootstock instructions if they want to go further. Does that sound reasonable? | 19:27 |
| rcn-ee | so maybe 8.04 just didn't like the "&>>"... format fatfs, copy bootloader, format ext, copy rootfs... | 19:27 |
| Jefro | very possibly. I'll try it on my laptop, which has 9.10 installed. | 19:28 |
| rsalveti | Jefro: pre-installed image is easier for the first moment | 19:30 |
| rsalveti | then you can point for advanced customizations | 19:30 |
| rsalveti | and also rcn-ee's kernel | 19:30 |
| rsalveti | in case people want to hack the normal ubuntu image | 19:30 |
| rcn-ee | rsalveti, you guys ready for another sru the next "xm"? ;) (u-boot).. | 19:31 |
| rsalveti | rcn-ee: haha :-) | 19:31 |
| rcn-ee | i saw them on the u-boot list, and went oh my..... ;) | 19:32 |
| rsalveti | rcn-ee: that's why for natty we'll be upgrading the x-loader/u-boot when needed | 19:35 |
| rsalveti | or at least warn the user that he needs to update it, and create a tool for it | 19:35 |
| rsalveti | but yeah, sru all around :-) | 19:36 |
| rsalveti | GrueMaster: later on if you want to help and have enough time, please help getting the qt trace | 19:36 |
| GrueMaster | Will do. | 19:37 |
| rsalveti | so we can find where and which instruction is breaking qt | 19:37 |
| rsalveti | I'd like to get some kind of qt benchmark, to compare the performance with and without neon | 19:37 |
| rsalveti | will try to dig one at the qt examples/tests/demos files at the git tree | 19:38 |
| Jefro | rsalveti rcn-ee thanks for the help | 19:38 |
| GrueMaster | Thats why I want to get my son involved. He can create one. | 19:39 |
| rlameiro | ogra_ac: are you running on the AC100? | 19:50 |
| rsalveti | GrueMaster: do you remember where you got the cpuburn package while stressing panda at dallas? | 19:52 |
| rsalveti | don't remember if vstehle gave us or we just got it somewhere | 19:53 |
| ogra_ac | rlameiro, yes, i do | 19:53 |
| vstehle | rsalveti, GrueMaster, you need to grab the latest cpuburn at http://pages.sbcglobal.net/redelm/ and compile the arm binaries | 19:54 |
| rsalveti | vstehle: cool, thanks | 19:54 |
| rlameiro | ogra_ac: How is it working? does everything works now? I am lining to buy one... on amazon | 19:54 |
| rsalveti | need to push that to our archive | 19:54 |
| rsalveti | orbarron: ^ | 19:54 |
| Jefro | rcn-ee - new data point, when I used 9.10 to write the card it did get all the way to "populating rootfs" but still doesn't boot: "No init found." and an (initramfs) prompt. | 19:54 |
| ogra_ac | rlameiro, nope, things are slowly getting better i think, but i havent tried any of the new hacks from phh yet | 19:55 |

| rlameiro | ok | 19:55 |
| rlameiro | i go to the ac100 to see if I can extract more info ;) | 19:55 |
| ogra_ac | they are just trying to get backlight on/off on lid close to work | 19:55 |
| cwillu_at_work | rcn-ee, poke poke | 19:56 |
| ogra_ac | i personally was traveling fo ra few weeks, just got back yesterday | 19:56 |
| rcn-ee | hey cwillu_at_work that zippy still failing? | 19:56 |
| cwillu_at_work | hey; only when I start up the network | 19:56 |
| cwillu_at_work | haven't been able to get any kernel messages out of it though | 19:56 |
| prpplague | cwillu_at_work: zippy giving you trouble? | 19:57 |
| rcn-ee | so every boot... how do you like the ck patchset? | 19:57 |
| cwillu_at_work | prpplague, ooo, both of you at the same time :) | 19:57 |
| prpplague | cwillu_at_work: zippy or zippy2 ? | 19:57 |
| cwillu_at_work | 2 | 19:57 |
| cwillu_at_work | prpplague, ks8851 troubles, specifically | 19:57 |
| cwillu_at_work | rcn-ee, nothing conclusive yet; I'm using it on this desktop, and it seems to be an improvement, although I'm waiting another week until I say that for sure | 19:58 |
| cwillu_at_work | (the problem with long uptimes is that you're never sure if things are faster because you rebooted, or because of the thing you changed that caused you to reboot) | 19:58 |
| rcn-ee | okay, cool... i have a patchset saved on my work machine for the ck stuff that i'm about to push.. ;) | 19:58 |
| rcn-ee | true true.. | 19:59 |
| cwillu_at_work | prpplague, want to know about my ks8851 troubles? :p | 19:59 |
| prpplague | cwillu_at_work: yea | 19:59 |
| cwillu_at_work | prpplague, cable plug events don't seem to make it to network manager et al | 20:00 |
| cwillu_at_work | prpplague, I hacked something up with mii-tool (which polls the mii status directly once per second) to simulate the behaviour | 20:00 |
| prpplague | cwillu_at_work: do the events show up on the CL level? | 20:00 |
| cwillu_at_work | nope | 20:00 |
| prpplague | interesting | 20:00 |
| prpplague | you using it with a panda or beagle? | 20:01 |
| cwillu_at_work | beagle | 20:01 |
| cwillu_at_work | c3 and c4 | 20:01 |
| GrueMaster | vstehle: pulling it now. | 20:01 |
| cwillu_at_work | prpplague, no, the _interesting_ part is that if I restart network manager _while_ copying data to a local machine _while_ mii-tool is running, everything dies | 20:01 |
| prpplague | right now i only have panda's at my desk, i'll have to pick up a beagle from the office to do some testing | 20:01 |
| prpplague | interestin | 20:02 |
| cwillu_at_work | I think I have a stack trace around still | 20:02 |
| cwillu_at_work | it dies in a weird fashion too :) | 20:02 |
| cwillu_at_work | processes go into uninteruptable state; I _think_ it's when they try to access the network, but I'm not certain (x will hardlock, for instance) | 20:02 |
| cwillu_at_work | sysrq-w shows them in that state though | 20:02 |
| cwillu_at_work | the end of the dmesg is a preempt count oops or something | 20:03 |

| cwillu_at_work | prpplague, I don't know that it's related, but:: I had rcn-ee compile me a 2.6.36 with ck2 (con kolivas's patchset with scheduler and vm changes) for kicks; it works fine under fairly heavy load for days, until I connect the zippy's ethernet and configure the interface; moments later, the system hardlocks | 20:21 |
| cwillu_at_work | I haven't been able to capture any messages from such a failure though | 20:22 |
| prpplague | just a rough guess would be that the communication with the KS8851 is getting part of the packet trashed and it is trying to read beyond the allocated packet | 20:22 |
| prpplague | i'd have to check but there were some similar problems reported with blaze | 20:22 |
| prpplague | (blaze uses the KS8851 in the exact same way as the zippy2) | 20:23 |
| cwillu_at_work | prpplague, I _don't_ get the problem unless I have both mii-tool running _and_ I restart network-manager _and_ there's network activity at the wrong time | 20:24 |
| cwillu_at_work | I've noticed this sporadically when poking a beagle remotely (i.e., the far end of a 128kb link), but I can trigger it every time if I scp a couple hundred megs locally, with "mii-tool -w" running, and then restarting network-manager with the transfer still running | 20:25 |
| cwillu_at_work | my guess is that mii-tool is holding something open that network-manager causes to be reset or whatever, at the same time as a packet comes in and does what you said before | 20:26 |
| cwillu_at_work | sporadically == once or twice a day | 20:26 |
| prpplague | interesting | 20:27 |
| cwillu_at_work | since I disabled my mii-tool hack, (restarting network-manager when an ssh connection dies rather than when mii-tool -w spits out a line), I haven't seen a single crash yet in two weeks | 20:27 |
| cwillu_at_work | I'm also suspicious that my ck2 crashes are related, given the scheduling changes + the "note: omap2_mcspi[14] exited with preempt_count 1" I get from a non ck2 kernel | 20:29 |
| cwillu_at_work | just can't prove it :p | 20:29 |
| cwillu_at_work | I've got several beagles and zippies and sd cards that I can duplicate this on, too :p | 20:29 |
| cwillu_at_work | (note, those two traces are on different kernels; the earlier was 2.6.35rc5, longer one was 2.6.35.7 | 20:32 |
| * cwillu_at_work pokes at prpplague | 21:06 | |
| cwillu_at_work | fixed it yet? :D | 21:07 |
| prpplague | cwillu_at_work: i'll have to see if i can replicate it on a beagle, all i have right now are pandas | 21:08 |
| cwillu_at_work | can a panda use a zippy2? | 21:08 |
