I suppose your kernel is built with "makeoptions DEBUG=-g".
Then enable kernel crash dump:
echo 'dumpdev="AUTO"' >> /etc/rc.conf
/etc/rc.d/dumpon start
After panic, get the baktrace from the dump using instructions from this page:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug-gdb.html
Or just run crashinfo and extract bt from generated core.txt.
Post bt here or to freebsd-hackers.
