Okay, I guess I have to recall my statement, I didn't realize it at first. Due to the i915.enable_hangcheck=0 it seemss that not simply the 3d died and Gnome3 WM died, but with this the screen went black and didn't react on anything. Interestingly there were no messages at all in the log files.
I could SysRq the computer, and the logfiles showed activity, but the screen remain black. I guess that is the sign of a hang.
