panic info

[David Reid]

These are the details of the most recent panic from my desktop amd64
machine. This happens less frequently than it used to (about every 36
hours now compared with every 12 before) and always seems to involve the
same functions.

GDB still doesn't seem to want to play, but I've enclosed the tr output
as was suggested.

Any suggestions about how to get more information next time it happens?
