After updating to kernel 3.3-rc1 I have experienced a lockup of my GPU. I left my KDE desktop running until the screensaver turned off the monitors. But on key presses it would not turn back on. Ctrl+Alt+F1 to switch to another virtual console also did not work. Alt+SysRq magic still worked, so I was able to force the syslog to disk and restart the system.
Can you test if attached patch help your case ?
Of course it would be best if we did not lockup in the first place.
