Kernel Bug Tracker – Bug 32402
Oops associated with radeon_unpin_work_func
Last modified: 2011-07-10 23:13:42 UTC
If this system (LFS build) is left idle for several hours with xscreensaver running(don't currently know which screen saver app. I am assuming one of the Mesa 3D ones) the system will oops. The system is locked solid and there is no trace in messages.old on reboot. The attached jpg is a photo of the screen at system failure. I first noticed the problem in 2.6.38-rc8 but have waited until now to report the problem in the hope of obtaining a more repeatable scenario.

Vary similar OOPS after hitting (esc) in Google-Crome to exit full screen video.
This was the URL:
As one could assume I maximized the video and then watched it to completion. After I pressed the esc key I got this BSOD.

Does reverting 69a07f0b117a40fcc1a479358d8e1f41793617f2 help?

Applied git revert to 2.6.39-rc2. Problem still present.
I'm having this problem too with kernel 2.6.38 series. As soon as my screen saver kicks in, my entire desktop gets corrupted. If I wait long enough for my screen to stand by or suspend (just the screen, not the computer), then the computer completely freezes. I'm not sure if I can add attachments to bugs reported by others; if so, I would be happy to attach a picture with the error messages.
Please, let me know how I can help with this issue.
An update: at least in my case, the problem seems to be related to page flipping in the radeon driver. I have disabled page flipping in my xorg.conf file and haven't seen the problem since.
Here's some related links:
I would first see the heavy screen corruption described in the second link above, and only later the kernel oops described in this bug report.
I'm sorry if my problem isn't directly related to this bug report, but the oops message is very similar to the one I was getting.

Thank you for the update I haven’t seen this problem in a while and
since then I've upgraded kernel and xorg/mesa.
I have another issue that I'm sure is unrelated where my system locks
up(no network not I/O) if I'm not running at least 3 facebook games:
deeprealms, castle_age and sororitylife.

Just a quick update to report that the fault is also present in the 2.6.39 kernel.

Ran the patch on 2.6.39 overnight (~9 hours) and there have been no problems the problem looks fixed for me.
A patch referencing this bug report has been merged in v3.0-rc3:
Author: Dave Airlie <firstname.lastname@example.org>
Date: Sun May 29 17:48:32 2011 +1000
drm/radeon: fix oops in ttm reserve when pageflipping (v2)
*** Bug 38232 has been marked as a duplicate of this bug. ***
Will this patch be pushed to the 2.6.39 series ? I don't see it in 126.96.36.199. I got a similar crash with 188.8.131.52, but it's strange that before moving to x86_64 and having to use an old Flash version (10.2p3 111710), because Adobe only make releases for x86, I never experienced the kernel panic. Aside the Flash version, the configuration was identical.
