Hi!

After upgrading RHEL6 to 2.6.28.x kernel, I have spontaneous "GPU hung"
5-6 times per day.
xorg-x11-drv-intel-2.11.0-7.el6.i686 driver for Xorg.

-----------------------------8<-------------------------------
Apr 25 12:36:02 bb-work kernel: [drm:i915_hangcheck_elapsed] *ERROR*
Hangcheck timer elapsed... GPU hung
Apr 25 12:36:02 bb-work kernel: [drm:i915_do_wait_request] *ERROR*
i915_do_wait_request returns -11 (awaiting 76525 at 76524, next 76526)
Apr 25 12:36:04 bb-work kernel: [drm:i915_hangcheck_elapsed] *ERROR*
Hangcheck timer elapsed... GPU hung
Apr 25 12:36:04 bb-work kernel: [drm:i915_reset] *ERROR* GPU hanging too
fast, declaring wedged!
Apr 25 12:36:04 bb-work kernel: [drm:i915_reset] *ERROR* Failed to reset
chip.

How can I help to debug this issue? Configs and logs attached. Thanks.
