We had a panic with a backtrace similar to the loc-up in (2.) today:

panic: sbappendaddr
backtrace:
breakpoint
vpanic
snprintf
sbappendaddrchain
udp4_sendup
udp_input
ipintr
softint_dispatch
DDB lost frame
Xsoftintr

Again, I do have show reg output if that helps.

This is getting scary. About every other time I tcpdump over a ssh connection 
to a 8.1 server, it locks up or panics. I never experienced anything close 
with 6.1.
