Ubuntu 12.04.2LTS on Intel i3-2120 with integrated hd2000 gpu

I never had this problem before, but after yesterday kernel update (3.5.0-26-generic) after few minutes dmesg start to show this error messages

[ 175.345408] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung

after about an hour Xorg hangs I can only move the mouse pointer

I attached /sys/kernel/debug/dri/0/i915_error_state
