Please read the original thread:
http://lists.freebsd.org/mailman/htdig/freebsd-stable/2004-November/009307.html

I couldn't get a crashdump on this machine, but I provided a lot of
information (traces) in that thread.

Since no one replied to my last post in that thread, I didn't know
what else to do. But if you tell me what else you want, I'll get it
for you immediately.
