I'm seeing the issue of hung GPU, after which a lot of applications (in
particular urxvt) become very messed up. Restarting X does not help for me.

  [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
  [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5 (awaiting
  3894 at 3893)
  [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung

Kernel 2.6.36-rc6.

enabled.

I'll give it a shot.
