--- Comment #23 from Arno Wald <arno.wald at netcologne.de> ---
I had the same error message in syslog after my Xorg has frozen. 

What happened:
* Xorg did freeze, only the mouse cuzsor could still be moved.
* I tried to switch to console (ctrl+alt+f1) but it did not work. Only the
mouse cursor did disappear, so I thought I had to reboot. (But I did not)
* After some time (1 minute or so) the switch to the console suprisingly did
happen.
* Switching back to X (ctrl+alt+f7) I have found X unfrozen and everything
working fine again.

In the syslog I have found:
