Public bug reported:
OS: Ubuntu 11.04
Kernel: Ubuntu 2.6.38-13.54-generic 2.6.38.8
hardware: Fujitsu Lifebook A531 with 1 extra external screen connected
Very frequently (often multiple times a day) the system seems to freeze. The
mouse is still active but I can't select anything. Switching to text console
sometimes works, sometimes switching doesn't work at all anymore. Killing the
X server the hard way doesn't work either.
kern.log shows the following messages after a reboot:
