crash with ipfw nat on mips32

[Adrian Chadd]

hi,

I'm updating my freebsd wifi bits in preparation for more work and ... well:

ath1: using multicast key search
random: harvesting attach, 8 bytes (4 bits) from ath1
  .. ipfw
ipfw2 initialized, divert loadable, nat loadable, default to accept,
logging disabled
  .. ipfw_nat
*** Setting kern.random.harvest.mask=511
kern.random.harvest.mask: 2047 -> 511
*** bringing up loopback ..
Trap cause = 2 (TLB miss (load or instr. fetch) - kernel mode)

Has anyone seen this?
