After upgrading my laptop (Dell 600m) yesterday, I have begun to

Killing the X server by Ctrl-Alt-Backspace is a good way to lock the
system. Reboot to get a core dump.

Ok, I'll try to look at this soon... It would be useful if you could
enable hw.dri.0.debug=1 and send me the debug output as well, if you
can get anything useful before it locks up.
I have not had luck reproducing a panic, but I can get the computer to
lock up at startup of the X server (rarely) and shutdown (often).
This may not be accurate, but I think I am able to shutdown safely if I
switch to a tty and wait until this debug line is printed:
[drm:pid13:vblank_disable_fn] vblank_disable_allowed=1
If I start rebooting before it is printed, the system locks up. Of
course, this is only after rebooting several times.
Here is a successful start and shutdown:

http://people.freebsd.org/~scf/Xorg.0.log
Does that help?
