[arrandale] Xorg occasionally freezes during activity

[Janne Moren]

Binary package hint: xorg

Occasionally the display will freeze, and a reboot is necessary. It always seems to happen when I do something graphical; by far most common is when I move between desktops using the pager or key combination, but it has happened once or twice at other times. I can log in using ssh, but killing X is impossible, necessitating a reboot.

All system-related info is hopefully attached to this report.

This is what I find with dmesg:
