[i845G]X freezes - [drm:i915_gem_idle] *ERROR* hardware wedged

[Nigel Atkinson]

[Report]
Computer randomly after awhile seems to almost shutdown, the video flickers and then constantly retries to start. The computer is still running, and I am able to ssh into it. Upon ssh'ing in - it tells me there are 0 users logged in, so I guess the gnome session has been terminated.

Not running compiz, the most intensive GUI app running was firefox.

This will go on and on until I reboot the machine.

After the last (II) line, it should be:

This particular machine is a server install with the Ubuntu-Desktop meta package added. However I have seen this happen on another identical machine with a plain Desktop install.
