| marcreichelt | hi there | 10:52 |
| marcreichelt | my ubuntu kernel seems to have problems with acpi - nearly every time when my laptop is under heavy use (e.g. reading big files from my external usb disk or burning a cd) it just hangs up with a kernel panic | 10:57 |
| marcreichelt | a shot of the screen can be found here: http://www.marcreichelt.de/misc/kernelpanic.jpg | 10:59 |
| marcreichelt | I tried to deactivate all modules containing the word "acpi", but this didn't fix the problem | 10:59 |
| marcreichelt | I also tried to deactivate acpi on boot, with "acpi=off" as kernel parameter | 11:00 |
| marcreichelt | the result was that the system frozed after approx. 30 seconds after boot time | 11:01 |
| marcreichelt | do you have any ideas? is this a bug in the ubuntu kernel? what can I do? | 11:01 |
| === marcreichelt is now known as marc_learning | ||
| mjg59 | marc_learning: "acpi_processor_idle" just means that the system wasn't doing anything at the time | 11:40 |
| mjg59 | But you can check by unloading the "processor" module | 11:40 |

| === fabbione [i=fabbione@gordian.fabbione.net] has joined #ubuntu-kernel | ||
| marcreichelt | hmm | 01:34 |
| marcreichelt | processor depends on speedstep_centrino, and I can't unload that one, because it is in use | 01:35 |
| marcreichelt | but it doesn't say by which module it is used | 01:41 |
| Mithrandir | it's probably used by powernowd or something similar. | 01:42 |
| infinity | No, you can't unload centrino. mjg59 and I ran into that a week or two ago. It's thpethul. | 01:43 |
| infinity | The only way I could "unload" it was to not load it in the first place. | 01:44 |
| marcreichelt | k | 01:45 |
| marcreichelt | how can I deactivate it on boot? | 01:45 |
| === BenC [n=bcollins@debian/developer/bcollins] has joined #ubuntu-kernel | ||
| marcreichelt | so that "processor" and speedstep_centrino aren't started at boot time? | 01:45 |
| infinity | Blacklist them in modprobe. | 01:45 |
| marcreichelt | Mithrandir, I killed powernowd | 01:45 |
| infinity | Alternately, move the files somewhere else so you're sure nothing can load them. :) | 01:46 |
| marcreichelt | moment... | 01:48 |
| marcreichelt | brb | 01:48 |
| marcreichelt | ok, I created the file /etc/hotplug/blacklist.d/asuslaptop-problems and wrote the line "processor" into it | 01:57 |
| marcreichelt | is this correct? | 01:57 |
| marcreichelt | I think it should be | 01:59 |
| marcreichelt | well, I'm going to reboot now | 01:59 |
| marcreichelt | see you in a few minutes | 02:00 |
| === marcreichelt [n=marc@P6115.pallas.wh.tu-darmstadt.de] has joined #ubuntu-kernel | ||
| marcreichelt | hello again | 02:12 |
| marcreichelt | my module "processor" is still running | 02:12 |
| marcreichelt | even a line in /etc/hotplug/blacklist did not work | 02:12 |
| marcreichelt | you still mean that it would be good to rename the module? | 02:13 |
| marcreichelt | k, I renamed the processor module | 02:14 |
| marcreichelt | brb | 02:14 |
| === marcreichelt [n=marc@P6115.pallas.wh.tu-darmstadt.de] has joined #ubuntu-kernel | ||
| marcreichelt | hi again | 02:19 |
| marcreichelt | he still loads the module "processor" - but I renamed processor.ko to processor.ko.old... :-/ | 02:20 |
| marcreichelt | maybe I have to create a new initrd? | 02:20 |
| marcreichelt | or kernel? | 02:21 |
| marcreichelt | or is there another way to fix my problem? | 02:22 |
| marcreichelt | I would hack myself into the kernel to solve this problem if I would have the time to | 02:23 |
| marcreichelt | the problem seems to be in processor.c | 02:24 |
| marcreichelt | :-( | 02:36 |

| marcreichelt | brr | 02:47 |
| marcreichelt | again a kernel panic | 02:48 |
| makx | what ubuntu version are you using | 02:49 |
| makx | blacklists should be under /etc/modprobe.d | 02:49 |

| makx | yes put it there | 02:50 |
| marcreichelt | moment | 02:50 |
| marcreichelt | makx, how should the blacklist look like? | 02:51 |
| marcreichelt | just a file containing the line "processor"? | 02:51 |
| marcreichelt | ? | 02:55 |
| === mxpxpod [n=BryanFor@wuw-ojr3gmca.dybb.com] has joined #ubuntu-kernel | ||
| makx | blacklist evbug | 02:56 |
| makx | for example | 02:56 |
| marcreichelt | k | 02:56 |
| marcreichelt | for me it is blacklist processor, then | 02:56 |
| marcreichelt | ok, brb | 02:57 |
| === marcreichelt [n=marc@P6115.pallas.wh.tu-darmstadt.de] has joined #ubuntu-kernel | ||
| marcreichelt | no, it didn't work | 03:02 |
| marcreichelt | he is still loading the module "processor" | 03:02 |
| marcreichelt | is there a kernel version which does not contain this bug? | 03:03 |

| BenC | marcreichelt: dpkg-reconfigure linux-image-`uname -r` | 03:50 |
| BenC | that will generate a new initramfs | 03:50 |
| mxpxpod | BenC: have you had any problems lately with your ae? | 03:52 |
| BenC | none | 03:52 |
| BenC | other than the weird eth0_clashed thing, but that's not particular to ae | 03:52 |
| mxpxpod | BenC: check this out... someone in my apartment installed a wireless router with authentication on the same channel as mine and my ae gets a ton of DEAUTH messages from it | 03:53 |
| mxpxpod | this causes klogd to go crazy and take up like 10% cpu | 03:53 |
| BenC | hmm, sounds like softmac actually | 03:53 |
| mxpxpod | if I switch to another channel, I don't get it | 03:53 |
| mxpxpod | oh, really? | 03:54 |
| BenC | maybe I need to turn down the verbosity | 03:54 |
| BenC | the messages I think come from softmac | 03:54 |
| mxpxpod | yeah, dmesg is full of DEAUTH's | 03:54 |
| mxpxpod | it's quite frustrating... so I switched channels | 03:54 |
| BenC | actually, it's right from ieee80211.ko | 03:55 |

| lamont | BenC: can you easily tell me when the last update of the hppa patch in 2.6.15 happened? (was -13 built with the hppa patchset, or without, to be specific...) | 06:09 |
| BenC | I've never applied an hppa patchset per se | 06:13 |
| BenC | I merely got what was there to work | 06:13 |
| BenC | lamont: so it's 99% stock 2.6.15 code for hppa, with just one backport for a compat syscall I can't recall off hand | 06:14 |
| lamont | BenC: please consider merging the following patches (minimum) from ftp://ftp.parisc-linux.org/patches | 06:19 |
| lamont | diff-2.6.12-rc3-tulip_21142_phyinit, diff-2.6.3-tulip, diff-2.6.6-tulip_stop_rxtx, diff-tulip_phy_reset-03 | 06:19 |
| lamont | all 4 are in akpm's tree | 06:19 |
| lamont | those patches make tulip work on modern hardware... bug exists on hppa as well as some i386 platforms | 06:22 |
| marcreichelt | BenC: just leave the processor blacklisted and generate a new initramfs? | 07:16 |
| fs | what's the current status of the megaraid newgen/legacy patch? | 07:21 |
| fs | never mind, found it: it's merged upstream. | 07:33 |
| lamont | BenC: I'll start working through the hppa patchset to see what makes sense for us to include | 07:35 |
| lamont | as in, what's low-risk and/or hppa specific | 07:36 |

| marcreichelt | ok, I give up | 08:44 |
| marcreichelt | the module 'processor' is still running | 08:44 |
| marcreichelt | maybe I'm just too stupid for this :-/ | 08:45 |
| BenC | marcreichelt: rm -f the module | 09:03 |
| marcreichelt | hmm | 09:07 |
| marcreichelt | or better mv module module.bak? | 09:07 |
| marcreichelt | ok | 09:09 |
| marcreichelt | root@tux:/lib/modules/2.6.12-10-386/kernel/drivers/acpi # mv processor.ko processor.ko.bak | 09:09 |
| marcreichelt | now I do dpkg-reconfigure linux-image-`uname -r` | 09:09 |
| marcreichelt | hmm | 09:10 |
| marcreichelt | root@tux:/lib/modules/2.6.12-10-386/kernel/drivers/acpi # dpkg-reconfigure linux-image-`uname -r` | 09:10 |
| marcreichelt | Not touching initrd symlinks since we are being reinstalled (2.6.12-10.26) | 09:10 |
| marcreichelt | Not updating image symbolic links since we are being updated (2.6.12-10.26) | 09:10 |
| marcreichelt | it seems that he didn't noticed anything | 09:10 |
| marcreichelt | I have to go | 10:23 |
| marcreichelt | see you | 10:23 |
