I am no *34 kernel version. The issue occurred with the latest ubuntu kernel version
uname -a: Linux 2.6.32-22-generic #36-Ubuntu SMP Thu Jun 3 19:31:57 UTC 2010 x86_64 GNU/Linux
As mentioned above the problem is similar to a few other intel related ones, e.g., https://bugs.launchpad.net/bugs/528467

** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  After a recent upgrade to Lucid, I get intermittent Xserver crashes resulting from a few days of uptime. Usually it happens when  power-manager kicks in to blank the screen. I get these message in the kern.log:
  Jun 13 01:21:22 domus kernel: [392077.221266] [drm:i915_hangcheck_elapsed] =*ERROR* Hangcheck timer elapsed... GPU hung

- Kernel seems to be intact: other services, like webserver works. I get a messages that a low graphics mode should be eneabled. And the dri/drm capablipities are being lost, unless I reboot the machine.
