This report is not very helpful (not helpful at all).  Please obtain at least 
a backtrace: 
http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/advanced.html#KERNEL-PANIC-TROUBLESHOOTING
http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug.html
(build in KDB and DDB and issue a "trace" when the panic shows up)

With what you have posted so far it's impossible to find the culprit.  
Nontheless, you might want to try to update src/sys/contrib/pf to RELENG_5 
(not RELENG_5_3 what you seem to have) to see if that improves the situation.
