Public bug reported: I am somewhat used to having GPU lockups hang X for me maybe once a week. I've followed a few vague bugs on the problem, but over the past weekend this has grown to every couple of hours.
Easy ways to trigger it: changing workspaces too quickly while there is disk activity, or letting the screensaver go into power saving mode on the screen. The last one requires a hard reboot and I end up with the screen in a very dim state after the boot. Have a kern.log, if it helps.
