Gary:

After it crashes, it locks up and hangs, no keyboard response, etc.  
When I reboot, I go into single user mode and do:

fsck -p
mount -a -t ufs
savecore /var/crash /dev/da0s1b     (which is my swap)

It says no dump available.  These instructions are from the handbook.

I just got sent a patch a little while ago which apparently will help 
the system not lock up.  I'm going to try it later today and see where 
it gets me.

Thanks,

Matt
