I installed the 3.5.0-28-generic (linux-image-3.5.0-28-generic_3.5.0-28.47~precise1_amd64.deb) from precise-proposed repositories and the problem is not fixed

dmesg show:
[ 854.728692] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung
[ 854.728696] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state
[ 855.232276] [drm:i915_reset] *ERROR* Failed to reset chip.

I also attached the /sys/kernel/debug/dri/0/i915_error_state file
