Hi, when I run glxgears in this kernel, X crashes. It happens also with
older releases and I don't know what is the first defunct.

In the log there is:
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
[drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5
(awaiting 2 at 0)
