I can consistently reproduce the "*ERROR* Hangcheck timer elapsed... GPU hung" message in the following conditions: using the new Google Maps interface with Chrome and WebGL hardware acceleration enabled. After a few seconds navigating in the Maps interface, the browser crashes and Unity freezes. I'm able to restore Unity by switching to the terminal, killing Compiz and switching back again. After restoring Unity, it seems that Chrome automatically disables hardware acceleration. You can see, attached, the results of about:gpu before and after the crash. After this point, Maps navigation does not crash the browser. However, by restarting the browser, hardware acceleration is back again, and I'm able to reproduce the same behavior.
