Freebsd 6-Stable lockups

well theseare the only additional lines ive added to my kernel
I pretty sure i added crypto support after the problems started
i have  disabled geli support for encrytped swap partitions as i thought 
that may bethe cause

# To make an SMP kernel, the next line is needed
options         SMP                     # Symmetric MultiProcessor Kernel



options         ALTQ
options         ALTQ_CBQ        # Class Bases Queueing

# TCP_DROP_SYNFIN adds support for ignoring TCP packets with SYN+FIN. This
options         TCP_DROP_SYNFIN         #drop TCP packets with SYN+FIN
