Kernel log
Sometimes the X server crashes due to a GPU lockup, caused by a page fault. It happens seemingly randomly, at irregular intervals (sometimes it takes several hours, sometimes it crashes in half an hour).
Before that happens, I see a small amount of corruption (noise around the cursor), then everything but the mouse hangs. After a while, the mouse also hangs, the screen becomes black with a "_" symbol in the upper right corner of the screen (but the mouse is still displayed), and after some more time the whole screen becomes corrupt in vertical blocks. If I press Ctrl+Alt+F1 fast enough, I can switch out of X and use the console for a while, otherwise the whole PC hangs and I need to do a hard reboot.
This issue may or may not be related to bug #69029 (the symptoms seem similar, but the errors are different).
I am using a GeForce 660 card on openSUSE 13.1 x86_64 Beta. I also reported the bug downstream.
