Bug#554145: Happened quite reproducably today

Hallo!

Happened almost everytime when I switched from tty7, display :0, to tty8,
display :1 and then back to tty7, display :0.

I know rebooted the laptop to exclude some old libs still in use effects. I
am using TuxOnIce snapshotting, thus it has not been rebooted before.

I was using tuned CFS -  Completely Fair Scheduling - settings, but I
resetted them to defaults before the last crash happened.

Backtraces look similar if not the same, here another example:

Restore TV PLL
Restore TVHV
Restore TV Restarts
Restore Timing Tables
Restore TV standard
Leaving Restore TV

Please try to get a debugging backtrace with gdb after installing
xserver-xorg-core-dbg and  libpixman-1-0-dbg
