Kernel Bug Tracker – Bug 9118
When using ACPI on a Compaq Presario V6221EU the laptop goes into deadlock after a random amount of time.
Last modified: 2007-11-18 04:21:00 UTC
Most recent kernel where this bug did not occur: 2.6.19
Distribution: Fedora Core (vanilla kernel from kernel.org)
Hardware Environment: Compaq Presario V6221EU
Software Environment: 32-bit(?) i386
Problem Description: Unless acpi=off is used, the laptop goes into deadlock after a while. I can't do ANYTHING except for a hard reboot. I tried several compilations (disable some hardware and other stuff) but that does not work.
Steps to reproduce: Use a Compaq Presario V6221EU and then boot with a quite recent kernel.
Btw, the logs did not show anything either... :(
Narrowed it down to the 126.96.36.199 (which works) --> 2.6.21 (which doesn't). More specs needed??????
I'm willing to put a lot of time into this, so please if anyone could help... I'll do everything.
Thanks, Ronald. Before someone from ACPI team gets to this, maybe you can try git bisect? Are you familiar with git?
I have read about git and I understand the concept of git and bisect but I have never used it. If you can point me to some documentation I can give it a try. I'm going to have to use the 188.8.131.52 till 2.6.21 part for the bisect right?
P.S. The laptop is now gone at the moment for a repair. It has been returned to the manufacturer for three times now. I will have it back next week (this bug is not related to this).
P.S. Before I'm going to start the bisect, I'm going to try the latest kernel first (2.6.24) of course :) .
Yes, 2.6.19->2.6.20, and you are right about trying latest first. To get the latest, git will also be handy. I just wrote to someone:

You are not on Debian, so you just get it on Fedora as rpm, or download from http://www.kernel.org/pub/software/scm/git/. All the kernel trees are at http://git.kernel.org/.
Fedora has git in its repo's. I'm executing the command as you suggested:
git-clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git linux-2.6
It's not going 'fast' , is that correct? Are there any ways to speed it up? Or to at least resume it?
Ok, Git works and I got the latest kernel and all. I will post my results after I have tested the laptop with the latest kernel :) .
Well, Ronald, even though, would you please post the dmesg output? if possible, /proc/acpi/dsdt and /proc/acpi/fadt would be helpful too.
Yesterday I got my laptop back and started to reïnstall everything on it. Then I used the stable 184.108.40.206 kernel. After that I used kernel-220.127.116.11 and the git kernel (2.6.24-rc3-g2ffbb837-dirty). No more deadlocks and ACPI works fine now. In the store they said that they replaced the entire mobo... . I think it's the same motherboard but this bug was probably caused by buggy hardware. (Weird because Windows Vista ran fine on it). Sorry for wasting your time...
