Public bug reported:

Binary package hint: xserver-xorg-video-intel

This bug is similar to Bug #555573, but I am posting a new bug because I
have slightly different log outputs and a different cause for the
problem.

Whenever I run a program that uses the GPU heavily, such as programs
that use OpenGL, I will get a GPU hang within a few seconds. The issue
seems to be related with how hard the GPU is working because I was able
to also get the problem when I moved around some tabs very quickly in
Chromium browser.

One program that was able to reproduce the problem was 3D Virtual
Creature Evolution under OpenGL rendering mode in Wine.

When the bug occurs, the display freezes up and I can move the mouse
only very slowly and choppily. It does not freeze up the whole system
since I am able to switch to a console and stop gdm. (This does not
cause the problem to stop. I have to reboot.) When I switch to the
console, I get lines that spam the terminal with:

 [118225.108016] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
 [118225.108186] [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5 (awaiting 2803178 at 2803174)

I am not sure which files to attach so feel free to ask me to attach
more. I will attach two files that have some relevant information.

Ubuntu 10.10 Maverick
Kernel 2.6.35-22-generic
GPU: Intel GMA 3000 with i915 driver
