>Description:
This problem existed in 6.1-RELEASE also.

Tried loading the IPFW module and it causes an immediate panic:

(on serial console)
# kldload ipfw
panic: trap: fast data access mmu miss
cpuid = 0
Uptime: 9m7s
Cannot dump. No dump device defined.
Automatic reboot in 15 seconds - press a key on the console to abort


system is 420R with 2x450MHz UltraSPARC-II processors, 4GB RAM

I can make this system available on the Internet with remote serial console if anyone wants to try it.
