ipfw doesn't work well on sparc64. It wasn't written to take architectures
with alignment constraints into account, so it causes these panics. The
author doesn't seem to acknowledge that such architectures exist.
You're probably getting this from the daily periodic scripts listing the
firewall rules, you could just comment that out of the periodic scripts.
I'll try to get this fixed before 5.1-RELEASE unless someone else beats me
to it.
