Bug description:
I am fairly frequently (maybe once every 2 days) seeing screen
lockups. The system is fine, and then screen locks up. mouse is still
movable and even changes icon based on content under it (ie mouse over
link changes to pointing hand). Programs are still running (often
this occurs during a google hangout, and the hangout, audio and mic
seem to work fine).
Today when this happened I had more patience and hit ctrl-alt-f1, and then
subsequently saw that dmesg had:

Normally, I'm generally able to switch consoles in and out of X
without problem. I do not know if the above trace is related to X
being locked or not.
I'll also attach the /var/log/Xorg.0.log.old that had some information
in it also andapparent segfault. That said, I think all log
information is tens of seconds after the lock up and might be a result
of me ctrl-alt-1 <-> ctrl-alt-f7 while system was in a borked state.
