Not sure if my bug belongs as part of #507504 or #555573 - posting it both places.
I can reproduce the 'Hangcheck timer elapsed... GPU hung' message and crash easily and reliably.
also getting the
 .. drm:i915_gem_idle] *ERROR* hardware wedged messages in the kern.log file
Environment : fresh install of 10.04 LTS, intel 915 video.

To make the crash happen :
Go to system->preferences->screen saver and select 'ant spotlight'
or 'GL Slideshow'. This PC will crash within 3 seconds reliably, over& over, as many times as I try.

To make crashes much less frequent :
Same menu, quickly before the ant starts revolving, select 'gl matrix' Floating Ubuntu or hyper-torus for the saver.
Crashes will still happen, just not constantly
anyway, an easy reproducable way to cause a crash may be helpful to somebody.
