[i915gm] GPU lockup (ESR: 0x00000001 IPEHR: 0x7d8e0001)

[Christian Göbel]

Binary package hint: xserver-xorg-video-intel

Testing Xubuntu beta1 plus latest updates on a Laptop with Intel-Centrino plattform.
I was just playing around with the settings of Xfce (not monitor/graphic-related) and this bug hit me (again).

First I god a corrupted screen for aprox. 2 second. Then the screen came back - mouse pointer could still be moved, however the screen was completely unresponsive.
If I try to restart gdm then Ctr-Alt-F8 just shows a black screen. Reboot is required.

This bug hits me roughly once per hour.
