2.6.4-rc1-mm2 ieee1394 and/or framebuffer crash

[Torrey Hoffman]

I got this while switching VC consoles during a large, long rsync backup
from my workstation's RAID0 "/home" to an external firewire drive.  I'm
using the Radeon framebuffer, if that matters?  

I doubt it was a coincidence that the crash happened while switching
consoles, since the rsync had been running for a long time before the
crash.

The kernel was compiled with SMP, preempt, HT scheduluer support,
register parameter passing, various kernel debug options.

Copied by hand from a digicam pic of the screen, hopefully accurately.
