Bug#587355: i915: X locks up when trying to play DVD on Thinkpad X40
Package: linux-image-2.6.32-5-686
Version: 2.6.32-15
Severity: important
I ran into this on a freshly installed Thinkpad X40 with todays
Debian/Squeeze. The external VGA connector is connected to a video
projector. I plugged in a USB DVD player, installed libdvdcss2 and
tried to play the DVD using vlc. This caused X to lock up and the
kernel to report a crash.
Searching for "Hangcheck timer elapsed... GPU hung" on bugs.debian.org
using Google, sent me to similar bugs, but not for this model. Some
bugs are <URL: http://bugs.debian.org/551803 >,
<URL: http://bugs.debian.org/573264 >,
<URL: http://bugs.debian.org/574478 > and
<URL: http://bugs.debian.org/576848 >. The last one point to a kernel
patch available from
<URL: https://bugs.freedesktop.org/show_bug.cgi?id=27187 > that is said
to fix a cache coherency issue. I have not tested it myself.
Before the crash, the VGA output would flicker a lot whenever the
machine was doing anything (like I moved the mouse or installed a
package), and the image would only stand still when I did not move the
mouse. This seem similar to the bug report
<URL: http://bugs.debian.org/570696 >, but I am not sure if it is the
same one.

[250593.976367] Fixing recursive fault but reboot is needed!
This was with xserver-xorg version 1:7.5+6 and
xserver-xorg-video-intel version 2:2.9.1-4.
As this is my video playing machine, I'll reinstall it with Lenny soon
to get my DVD player back, but thought it best to report the problem
before I reverted the machine into a working condition. Is there
anything I should test before I do this?
This is the output from 'lspci -nn':
