Since v3.9, when running Ubuntu 13.04 with the X and Mesa stack from
https://launchpad.net/~xorg-edgers/+archive/ppa, I have been getting frequent
hangs on my Thinkpad E220S running with a Sandy Bridge (8086:0116/Core
i5-2537M) GPU:

In v3.9.x, X would freeze up, and I would have to kill X via Alt+SysRq+K in
order to get out of the situation, but in v3.10 it looks like it's at least
able to unhang itself without crashing X.
