I thought I would add another panic report. This seemed to coincide
with an upgrade I made today. So if it is a software problem it
happened between Nov 21 and Dec 5. It happened on two computers that I
upgraded, so I suspect its not a hardware problem. One of the computers
had crash dumps switched on. The panic happened right after I issued a
reboot. The crash dump doesn't look very useful, but here it is anyway.
