To be of any use we need a backtrace.  See=20
http://www.freebsd.org/doc/en/books/developers-handbook/kerneldebug.html
for details.  First you need to configure a dump device then when
the system crashes a crash dump will be written to /var/crash by
default.  You then run kgdb on the file to get the backtrace.
