So while the unstable, reverse-engineered ATI drivers were locked up (which is
usual, it happens ~5 times a day on average), I pressed the ATX power button to
initiate a clean shutdown (statistically, this usually succeeds). During the
shutdown procedure, a panic occurred. (As a result, the filesystem wasn't
cleanly unmounted.)
I was doing a ``git pull --rebase'' (which turned out to have succeeded) when
the driver lockup occurred.
The crashinfo output is attached. Note: the kernel used during the panic has no
debugging symbols; a version compiled with debugging symbols was used for
crashinfo.
