| colonelqubit | I filed a hibernation bug about a month ago and I've been unable to fix it myself (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/366264). | 04:21 |
| ubot3 | Malone bug 366264 in linux "[Dell XPS m1530] Resume fails after hibernate/suspend" [Undecided,New] | 04:21 |
| colonelqubit | Is this the right place to ask for help in diagnosing and fixing this bug? | 04:21 |
| colonelqubit | is there somewhere else I should ask for help with this bug? | 04:30 |
| johanbr | colonelqubit: remove "splash" and "quiet" from your kernel boot line | 04:59 |
| johanbr | that should give you some more idea what's wrong | 04:59 |
| colonelqubit | johanbr: will do | 04:59 |
| colonelqubit | johanbr: should I edit menu.lst, or just temporarily change the boot params in the grub menu and then try to test suspend? | 05:03 |
| johanbr | colonelqubit: doesn't really matter | 05:09 |
| johanbr | it's mostly for debugging, so maybe the temporary way is best | 05:10 |
| colonelqubit | johanbr: what should I be looking for? I've been reading notes on the wiki (https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume), but I'm not sure if there's specific info I should put on the bug. | 05:11 |
| johanbr | well, it looks like it locks up, right? | 05:11 |
| johanbr | just write down what the last few messages are | 05:11 |
| colonelqubit | johanbr: yes, it looks like it locks up. I'll append the longer kernel log to the bug | 05:13 |
| johanbr | alright | 05:14 |
| johanbr | gotta go... good luck | 05:14 |
| colonelqubit | johanbr: thanks for the help -- should I ping back to #ubuntu-kernel once I've done this? | 05:14 |
| johanbr | sure, that doesn't hurt | 05:16 |
| johanbr | although most of the kernel guys are probably asleep now :) | 05:16 |
| colonelqubit | okay, I'll try tomorrow morning | 05:16 |
| johanbr | alright | 05:17 |
| colonelqubit | have a good night | 05:17 |
| johanbr | same to you | 05:18 |
| Yingying_Zhao | Which kernel will Karmic final use? | 10:32 |
| cooloney | Yingying_Zhao, we decided to use 2.6.31 | 10:46 |
| apw | yep 2.6.31 is the aim | 11:21 |
| === apw changed the topic of #ubuntu-kernel to: Karmic Kernel Plan: 2.6.31 -- Ubuntu Developer Summit this week. info on http://summit.ubuntu.com - and in #ubuntu-devel-summit | ||
| apw | cking, we were musing about doing a small image for testing of new features on usb | 11:22 |
| cking | apw, jaunty or karmic? | 11:23 |
| apw | do you have any canned way of making those or is this something we need to think about | 11:23 |
| apw | i t | 11:23 |
| apw | i think the though was making a karmic job with x-edgers, updated kernels and grub2 | 11:23 |
| apw | and somehow making all that fit in 0MB (of course) | 11:23 |
| apw | so it would be trivial to download and test as a bootable image not installed | 11:24 |
| cking | apw: I just do a clean install to a 8GB USB pen drive and then remove the bloaty apps then shrink the partition using gparted | 11:25 |
| apw | how small do you think it might go? | 11:25 |
| cking | Mmm.. 2.2GB was everything, so possibly down to less than 2GB and compressed down to 600MB | 11:26 |
| apw | so not exacty tiny then | 11:26 |
| apw | my chroots which contain X are of the order of 550MB | 11:28 |
| cking | I've got a minimal gnome lpia installer which is ~450MB | 11:28 |
| cking | (compressed) | 11:28 |
| apw | thats not the 100MB i was hoping for ... though it was a naieve wish | 11:29 |
| cking | 100MB is just not possible | 11:29 |
| cking | apw: would a 500MB image be reasonable? | 11:33 |
| apw | frankly i don't think it was me who cared how big it is | 11:34 |
| apw | i think the utility to both the user and us outweighs the size downsides | 11:34 |
| cking | apw: do you want this image to be produced automatically? | 11:45 |
| apw | cking, i am not seeing a need for that ... | 11:47 |
| apw | i can just update it and remake it etc pretty easy once i have a basic one | 11:47 |
| cking | I suggest downloading the latest image, install it to a 8GB USB stick and removing all the bloaty apps and shrinking it with gparted and working with this as a basis. | 11:48 |
| apw | cking, yeah sounds like a reasonable plan indeed | 13:27 |
| ogra | moo | 14:40 |
| Sam-I-Am | oink | 14:41 |
| ogra | root@osiris:~# grep CPU_FREQ_DEBUG /boot/config-2.6.30-6-generic | 14:42 |
| ogra | # CONFIG_CPU_FREQ_DEBUG is not set | 14:42 |
| ogra | hrm | 14:42 |
| smb | ogra, trying to find something. But mjg59 if you happen to hang around. Would you know a way to prevent a build-in acpi-cpufreq from getting selected? | 14:43 |
| smb | ogra, The whole of acpi debug is disabled by default | 14:43 |
| ogra | yeah | 14:43 |
| mjg59 | smb: No | 14:43 |
| ogra | we should probably have it on during development | 14:43 |
| mjg59 | Why would you want to? | 14:44 |
| ogra | my system is constantly running the fan and the frequency doesnt go below 1GHz since the modules were included in the kernel by default | 14:44 |
| smb | mjg59, To try to check what driver would get used next. ogra has a case where he had a lower freq avalable before but not with the acpi driver | 14:44 |
| ogra | i'd like to have my 800MHz default back :) | 14:44 |
| mjg59 | What hardware is this? | 14:45 |
| ogra | model name: Intel(R) Core(TM)2 Duo CPU T5550 @ 1.83GHz | 14:45 |
| mjg59 | And now what's the lowest speed? | 14:45 |
| smb | mjg59, 1Ghz | 14:46 |
| mjg59 | acpi-cpufreq is the only correct driver for that chip | 14:46 |
| mjg59 | If it's missing a state now then that implies that there's been a code change rather than a driver change | 14:47 |
| mjg59 | Unless you were somehow using p4-clockmod previously, in which case your life is now immeasurably better than it was then | 14:47 |
| ogra | i'm pretty sure with the modules a different direver was used | 14:47 |
| ogra | *driver | 14:47 |
| ogra | not sure if it was the right one, but it definately scaled to a lower speed by default | 14:47 |
| mjg59 | Other than acpi-cpufreq, only p4-clockmod could possibly bind to that chip | 14:48 |
| smb | mjg59, Yeah, that was somehow my suspicion | 14:48 |
| mjg59 | And that doesn't do voltage scaling | 14:48 |
| ogra | yeah, might be that it was the p4 one | 14:48 |
| mjg59 | So things are now better than they were previously | 14:48 |
| ogra | my lappie is most of the time on AC ... what i care for is the constantly running fan | 14:48 |
| mjg59 | It'll run coler at 1GHz with acpi-cpufreq than at 800MHz with p4-clockmod | 14:49 |
| mjg59 | s/coler/cooler/ | 14:49 |
| ogra | hmm | 14:49 |
| mjg59 | V^2/R and all that | 14:49 |
| ogra | then why does it run constantly even though thermal_zone only shows 55°C ? | 14:49 |
| mjg59 | Because the lowest trip point is below 55C? | 14:49 |
| ogra | root@osiris:~# cat /proc/acpi/thermal_zone/TZ0/trip_points | 14:51 |
| ogra | critical (S5): 91 C | 14:51 |
| ogra | not really | 14:51 |
| mjg59 | Oh, so it's all BIOS controlled anyway | 14:51 |
| ogra | i have no BOIS option for it though | 14:51 |
| ogra | *BIOS | 14:51 |
| mjg59 | You typically won't | 14:51 |
| ogra | well, it used to only spin up once an hour or so when the machine was idling | 14:53 |
| stgraber | ogra: got my mail ? | 14:53 |
| ogra | until the whole stack of cpufreq/thermal moved into the kernel | 14:53 |
| stgraber | oops, wrong chan :) thought I was in #ltsp, sorry | 14:53 |
| mjg59 | ogra: Shrug. | 14:54 |
| mjg59 | ogra: If you were using p4-clockmod before then your machine was running hotter. That's a thermodynamic certainty. | 14:54 |
| smb | Probably with p4-clockmod the temp was slightly lower at 800MHz | 14:54 |
| mjg59 | smb: No | 14:54 |
| smb | Ok, that would have been my only way to explain this | 14:55 |
| mjg59 | smb: Power consumption is linear with frequency, but tends towards a V^2 relationship with voltage scaling | 14:55 |
| smb | Hm, and iirc the p4 driver did only freq scaling | 14:56 |
| ogra | is there any way to tell acpi-cpufreq to use 800MHz ? | 14:56 |
| mjg59 | ogra: It uses whatever frequencies your BIOS provides | 14:57 |
| smb | mjg59, Could a custom dsdt override the frequencies? | 14:58 |
| mjg59 | Yes | 14:58 |
| mjg59 | But if you're driving the chip at lower voltages then it's designed to, then you risk data corruption | 14:58 |
| mjg59 | And just dropping the frequency won't save you anything | 14:59 |
| mjg59 | It just means you spend less time in deep C states | 14:59 |
| apw | ogra, i am a little supprised you have no 800mhz given the model you have thre | 15:00 |
| apw | my model, looks like a later version of yours and has 800 available | 15:00 |
| mjg59 | The frequencies available are determined by the bios, not the CPU | 15:00 |
| ogra | my system is a clevo tn120 | 15:01 |
| apw | interesting ... i'd not thought of it that way | 15:01 |
| mjg59 | ogra: Stick the output of acpidump somewhere? | 15:01 |
| ogra | wow, thats huge | 15:01 |
| mjg59 | Yes | 15:01 |
| mjg59 | Don't pastebin it | 15:01 |
| ogra | http://people.ubuntu.com/~ogra/acpidump.out | 15:03 |
| mjg59 | Hm. | 15:07 |
| smb | mjg59, Triying to learn a bit more here. What would be the thing to look at? | 15:08 |
| mjg59 | smb: You want the _PSS object | 15:08 |
| mjg59 | It contains the set of ACPI performance states | 15:08 |
| smb | Ok, seems to be referenced in ssdt2 and dsdt | 15:09 |
| mjg59 | Except it's not actually present in them | 15:09 |
| mjg59 | There's probably a dynamically loaded table | 15:09 |
| smb | I see... hm | 15:11 |
| smb | mjg59, That _tss method in ssdt2 looks slightly like setting up something oneshot... | 15:14 |
| mjg59 | _TSS is for T-states, not P-states | 15:14 |
| smb | mjg59, sigh, quite confusing. It walks through the p-states to build the t-states... or so it looks... | 15:21 |
| mjg59 | Yeah, I'm not sure what it's doing there | 15:21 |
| * ogra is back from his phonecall | 15:35 | |
| smb | ogra, Unfortunately I seem to be far from understanding what your BIOS does... :( | 16:02 |
| ogra | well, dont ask me about it either :) | 16:03 |
| smb | ogra, I won't :) | 16:03 |
| snakie | Hi, I'm looking for a download location for the .ddeb containing debug information on 2.6.28-12-generic for jaunty. Do any mirrors exist or are the 2.6.30 versions on ddebs.ubuntu.com the only available versions? | 16:23 |
| apw | i believe ddebs.u.c is the place for those | 16:35 |
| snakie | yes, do you know where to find older kernel versions as ddebs.u.c only has 2.6.30 | 16:37 |
| cwillu | hey, anyone want to look at a dmesg dump from a laptop that slowly dies after resuming from suspend? | 17:40 |
| cwillu | 2.6.30rc7 from the mainline kernel ppa | 17:40 |
| cwillu | http://pastie.org/496676 | 17:40 |
| cwillu | The process that triggers the first oops is varies, but it's always "BUG: unable to handle kernel paging request at <address>" | 17:40 |
| cwillu | s/is// | 17:40 |
| cwillu | I have an ssh open to it, so I can paste additional information, although at this point not much actually runs (dmesg does for instance, new gnome-terminal windows can open, but new bash processes don't start) | 17:42 |
| johanbr | the disk doesn't come back to life properly? | 17:42 |
| cwillu | it kinda does | 17:43 |
| cwillu | it's weird | 17:43 |
| cwillu | I can resume and use it normally for a while | 17:43 |
| cwillu | and then things start breaking | 17:43 |
| cwillu | at which point, any access to the disk seems to hang the process that made the access | 17:43 |
| cwillu | under our .30 kernel, it hangs almost immediately on resume (on the order of a few seconds to a few minutes). on mainline, it works for several minutes to several hours | 17:44 |
| cwillu | https://bugs.launchpad.net/bugs/380807 has some info from the -generic kernel | 17:45 |
| ubot3 | Malone bug 380807 in linux "[karmic, intel] Laptop locks up moments after resuming from suspend" [Undecided,New] | 17:45 |
| pgraner | apw: can you get the bug above [380807] into the Suspend/Resume queue? | 17:48 |
| cwillu | would ssh access to the box in this state be useful? | 17:48 |
| pgraner | cwillu: yes don't knock it down just yet | 17:48 |
| apw | it would be useful to know are able to login to it remotly | 17:49 |
| cwillu | pgraner, yep, it's still up, and I can reproduce it fairly easily | 17:49 |
| pgraner | apw: I think he had a ssh up prior to the oops | 17:49 |
| cwillu | (sec, attaching dmesg to that bug, and then I'll see if I can ssh in a second time) | 17:49 |
| pgraner | apw: looks like we have mem being mapped into the ether | 17:49 |
| cwillu | bah, ssh session just died | 17:52 |
| bjf | pgraner, are we having an IRC meeting tomorrow? | 17:52 |
| cwillu | desktop session is still up though | 17:52 |
| cwillu | dmesg is attached to that bug now (same as the pastie) | 17:53 |
| cwillu | pgraner, if you had one command that you could see the result of, what would it be? (noting that it may just hang the last remaining terminal I have open) | 17:54 |
| cwillu | (can still run dmesg, but have no way to copy it elsewhere) | 17:54 |
| apw | any commands you run,. run in the background fo & | 17:55 |
| apw | and then if they hang you'll likely keep your shell | 17:55 |
| cwillu | k | 17:55 |
| cwillu | wasn't sure if it would lock it up too | 17:56 |
| apw | it may... | 17:56 |
| apw | do you have KMS enabled? | 17:56 |
| cwillu | and... gnome-terminal just died | 17:56 |
| cwillu | (independently of any other commands, just stopped responding) | 17:57 |
| apw | damn | 17:57 |
| pgraner | bjf: we should be meeting, I need to look at the page and see who is chairing it | 17:57 |
| cwillu | and there goes compiz, although I can still move the mouse :p | 17:58 |
| bjf | pgraner, I asked because I think I am chairing. | 17:58 |
| apw | cwillu, so this is triggered by a suspend/resume i assume ? | 17:58 |
| cwillu | apw, yes, every time | 17:58 |
| pgraner | bjf: heh, cool. I think just putting out a summary of kernel actions out of UDS would be good. | 17:58 |
| Sam-I-Am | cwillu: i might recommend using 'netconsole' on the next boot | 17:58 |
| apw | you don't have an mmc card inserted do you? | 17:59 |
| cwillu | nope | 17:59 |
| cwillu | desktop is locked up completely now (no mouse, etc) | 17:59 |
| apw | mouse too ... hmm | 17:59 |
| cwillu | sysrq-s hit the disk though | 17:59 |
| pgraner | cwillu: is this a laptop or desktop? | 17:59 |
| cwillu | laptop | 17:59 |
| Sam-I-Am | if you configure netconsole it'll dump all the kernel output to a udp port somewhere... like syslog | 17:59 |
| cwillu | suspend was rock stable from 7.04 up to 9.04 | 17:59 |
| cwillu | Sam-I-Am, next reboot :) | 18:00 |
| Sam-I-Am | heh | 18:00 |
| pgraner | cwillu: 2.6.30 got an overhaul of the suspend/resume subsystem | 18:00 |
| apw | who was talking about locking issues in -rc6 for suspend? who told us about that | 18:00 |
| pgraner | apw: marcel was telling us at UDS | 18:01 |
| cwillu | apw, I saw a bug about that I think, I might have it open still | 18:01 |
| apw | cwillu, be good to have any pointers you have found already to save time | 18:01 |
| pgraner | apw: perhaps and apport-collect to make sure you have everything? | 18:02 |
| cwillu | pgraner, the attachments on my bug were from apport-collect | 18:02 |
| cwillu | http://patchwork.kernel.org/patch/1113/ | 18:03 |
| pgraner | cwillu: cool | 18:03 |
| cwillu | that's old though | 18:03 |
| cwillu | january | 18:03 |
| cwillu | just noticed the date | 18:03 |
| cwillu | there's 3 vaguely similar bugs on launchpad that I saw, all against 2.6.28 though | 18:04 |
| cwillu | I'm going to reboot and get it reproducing again | 18:04 |
| apw | cwillu, looks interesting as i am sure that same routine appears in suspend | 18:04 |
| apw | and so far i've not seen that change as presented in the kernel | 18:05 |
| cwillu | do you want me on ubuntu's kernel or mainline's? | 18:05 |
| cwillu | both have the problem, ubuntu's crashes far quicker though (almost too quickly to do anything with) | 18:05 |
| cwillu | other interesting datapoints, I _think_ it worked fine while I was still on jaunty with 2.6.30rcX (needed it to work around the ext4 file deletion hanger) | 18:06 |
| apw | cwillu, so that was with a mainline kernel? your own build? | 18:06 |
| cwillu | although you should probably ignore that, I don't remember at all well enough | 18:06 |
| cwillu | apw, mainline ppa | 18:06 |
| apw | so that should still be on your machine and testable on karmic too | 18:07 |
| cwillu | apw, you misunderstood me :p | 18:07 |
| cwillu | apw, both the mainline ppa kernel and ubuntu's -generic do this | 18:07 |
| cwillu | that dmesg came from 2.6.30rc7 from the mainline ppa | 18:07 |
| apw | ok ... | 18:08 |
| * cwillu reboots into 2.6.30-020630rc7-generic | 18:08 | |
| johanbr | any major differences in userspace suspend between jaunty and karmic? | 18:08 |
| apw | the patch you pointed to on patchworks is somehow in karmic under a different patch id | 18:08 |
| apw | johanbr, outside the kernel no, inside some | 18:08 |
| cwillu | how do I verify that I'm not using kms? | 18:09 |
| cwillu | I played with plymouth during jaunty's release (as long as I was on 2.6.30 and all that) | 18:09 |
| apw | unless you have modeset mentioned on your grub command line | 18:09 |
| cwillu | thought I removed it completely | 18:09 |
| apw | or in your module options then you don't | 18:09 |
| apw | it is opt in currently | 18:09 |
| cwillu | k, should be clear then | 18:10 |
| johanbr | cwillu: how do you suspend? | 18:11 |
| cwillu | johanbr, normal suspend | 18:11 |
| cwillu | not uswsusp or anything like that | 18:11 |
| apw | cwillu, another good test point would be the tip of linus' tree: http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2009-05-30/ | 18:25 |
| cwillu | apw, k, downloading it right now | 18:25 |
| apw | there are some locking changes for suspend in there, though i think they are meant to be more theoretical to be fair | 18:25 |
| cwillu | is there an easy way to force a message so I can see if this netconsole is actually working? | 18:26 |
| apw | hrm | 18:26 |
| apw | sysrq help might do it | 18:26 |
| apw | i think the title is always emitted | 18:26 |
| cwillu | yep | 18:26 |
| cwillu | good | 18:26 |
| cwillu | (in the sense of 'it worked') | 18:26 |
| apw | also worth doing the suspend from vt1, as you may see errors there | 18:26 |
| cwillu | messages that wouldn't show up in /var/log/{messages/kern.log/syslog/dmesg}? | 18:27 |
| apw | depending on the nature of the hang they might not get to disk yes | 18:28 |
| cwillu | the oops that starts to bring things down doesn't necessarily occur right away | 18:29 |
| cwillu | I'll still try it, I'm just spewing everything I can think of that might be relevant | 18:30 |
| cwillu | 8 minutes until the download is complete, at which point I'll install, and then suspend on the current kernel | 18:30 |
| cwillu | or should I go straight to the daily and see if it reproduces first? | 18:30 |
| * cwillu pokes apw with an inquisitive stick | 18:32 | |
| apw | i think continue with your test on the current, and then the c-o-d kernel | 18:32 |
| cwillu | k | 18:33 |
| cwillu | installing right now | 18:39 |
| cwillu | suspending from console | 18:47 |
| cwillu | hard lock | 18:48 |
| cwillu | 9 segfaults are visible, laptop_mode mostly, and one cpufreq | 18:49 |
| cwillu | I think I saw another error flash by too | 18:50 |
| * cwillu reboots and tries that again | 18:50 | |
| cwillu | nothing showed up in the netconsole | 18:50 |
| cwillu | actually, that's a lie | 18:50 |
| cwillu | [drm:i915_get_vblank_counter] *ERROR* trying to get vblank count for disabled pipe 0 | 18:50 |
| cwillu | show up | 18:50 |
| johanbr | cwillu: could you try with the jaunty kernel? | 18:51 |
| cwillu | johanbr, sure, doing it now | 18:51 |
| cwillu | (noting that jaunty's kernel has ext4 issues that causes other lockups) | 18:51 |
| cwillu | (but I shouldn't run into them without deleting files) | 18:52 |
| * cwillu suspends | 18:55 | |
| cwillu | came back with no errors on the console | 18:56 |
| cwillu | 2.6.28-10-generic #33 | 18:56 |
| cwillu | netconsole didn't show anything during the suspend, although it's still connected (I did a sysrq-sync before and after, both showed up in the netconsole) | 18:57 |
| cwillu | johanbr, apw, given my original dmesg, is there anything that jumps out at you as a way to check whether something has gone wrong, even before the system oops? | 18:58 |
| cwillu | something in /proc/ or /sys/ I could check? | 18:59 |
| johanbr | Comparison with the dmesg from the jaunty kernel might be interesting | 19:02 |
| cwillu | I'll post that in a minute | 19:06 |
| cwillu | just proving to myself that it's stable | 19:06 |
| cwillu | by playing flash games on casualcollective.com of course :p | 19:06 |
| cwillu | seems to be fine | 19:13 |
| cwillu | okay, dmesg | 19:13 |
| cwillu | http://pastebin.com/f3757f4a5 | 19:14 |
| cwillu | was the original with the fault http://pastie.org/496676 | 19:14 |
| cwillu | (bah, pastie was with fault, pastebin was jaunty's kernel that worked fine) | 19:14 |
| * cwillu pokes johanbr and apw | 19:15 | |
| cwillu | I'm rebooting into the daily 2.6.30 now | 19:15 |
| * cwillu suspends current daily kernel | 19:18 | |
| cwillu | dmesg from 2.6.30-999-generic (current daily): http://pastebin.com/f162d6f02 | 19:20 |
| cwillu | didn't immediately crash, let me test it for a bit again | 19:20 |
| cwillu | oh, wait | 19:22 |
| cwillu | an error showed up a second after I pastebin'ed it | 19:22 |
| cwillu | [ 261.585748] EXT4-fs error (device sda1): ext4_lookup: deleted inode referenced: 12206095 | 19:23 |
| cwillu | [ 261.585768] Aborting journal on device sda1:8. | 19:23 |
| cwillu | johanbr, apw: http://pastebin.com/f5c2ec258 has the latest error included | 19:23 |
| cwillu | opinions? | 19:25 |
| cwillu | I'm tempted to remount rw and see if there's any further instability, | 19:26 |
| * cwillu reboots to fsck and repeat | 19:28 | |
| cwillu | fsck finished, suspending agani | 19:33 |
| cwillu | well, suspending after rebooting :/ | 19:33 |
| apw | cwillu, hrm. can we get all that info into the bug, and i'll have a look about. especially the version you are stable on | 19:38 |
| cwillu | apw, yep. I'm not completely convinced the last crash was the related, but I'll post the dmesg's | 19:38 |
| * apw has to pop out ... | 19:39 | |
| * cwillu tackles apw to hold him in the channel :p | 19:39 | |
| cwillu | the daily hasn't done anything odd yet | 19:52 |
| cwillu | I'm going to keep poking it for a couple hours (longest I've ever had a suspend last and still crash) | 19:52 |
| cwillu | apw, updated the bug report with jaunty's dmesg | 19:56 |
| * cwillu suspends again for kicks | 20:22 | |
| cwillu | apw, it's still a little early to be sure, but I've suspended a couple times without rebooting on the daily kernel, and I haven't had any issues except for that first attempt with the ext4 mounting read-only, which may have been related to previous crashes more than the suspend | 20:23 |
| apw | cwillu, thats encouraging ... if you have an oppotunity to do say 10 suspends and report back on the bug that would be handy | 20:38 |
| cwillu | definitely | 20:39 |
| * cwillu suspends again | 20:39 | |
| cwillu | [ 4022.240004] BUG: soft lockup - CPU#0 stuck for 61s! [python:8575] | 20:41 |
| cwillu | lots of b44: eth2: Error, poll already scheduled | 20:45 |
| cwillu | apw, how likely is it that a daily would have random crashers in it? | 20:46 |
| cwillu | apw, just completed 20 suspend cycles on the daily, 60 seconds between each resume and the next suspend. Nothing suspicious shows up in dmesg, I'm posting it to the bug report | 21:22 |
| colonelqubit | johanbr: hi again. I've had some progress in testing hibernation on my laptop. | 21:36 |
| johanbr | alright | 21:38 |
| johanbr | I'm about to head out, but go ahead... | 21:38 |
| colonelqubit | if I disable splash/quiet and enable no_console_suspend, and hibernate from vt1, and never try to go to vt7 (with X), then hibernation and resume works (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/366264) | 21:39 |
| ubot3 | Malone bug 366264 in linux "[Dell XPS m1530] Resume fails after hibernate/suspend" [Undecided,New] | 21:39 |
| colonelqubit | I'm getting errors about btusb_intr_complete and btusb_bulk_complete. They appear to have "failed to resubmit" | 21:40 |
| johanbr | that shouldn't matter very much | 21:49 |
| colonelqubit | okay | 21:49 |
| colonelqubit | johanbr: As I said, it appears that I can get hibernation to work properly in vt1, but I can't hibernate from within X or return to X once I've gone though a hibernation cycle. Any suggestions on what I should try testing next? | 22:06 |

| maxb | It is intentional that ddebs.ubuntu.com only provides karmic ddebs? | 22:37 |
| cwillu | maxb, I see a bunch of different releases in /dists/ | 22:38 |
| maxb | Sorry, for the kernel I mean | 22:39 |
| maxb | pool/main/l/linux/ only seems to have karmic packages | 22:39 |
