Same problem here on a ThinkPad X220, Ubuntu 12.04 with LTS Enablement Stack and Kernel 3.5.0-26.40~precise1

syslog shows:
Mar 2 12:10:21 xyzzy kernel: [ 537.333056] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung
Mar 2 12:10:21 xyzzy kernel: [ 537.333060] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state
Mar 2 12:10:21 xyzzy kernel: [ 537.342329] [drm] Enabling RC6 states: RC6 on, RC6p off, RC6pp off

I'll test with the mainline kernel later.
