I have 2 new i7 machines using the nouveau driver and every couple of days the X display locks. I can ssh to it from another machine and bring it down gracefully. It needs to be powered off and restarted to get it back into a usable state. If I just reboot it, tends to lock up before I can login. KVM seems to aggravate the problem in that if I have virtual machines running the problem happens sooner. IOW I get longer uptimes between lockups if the virt machines are shutdown. I am not sure if that is relevant or not. FWIW I filed Bug 559791 but so far no one has provided any feedback.
