Blows up REAL good on my 6xamd64 box. Within a minute or two.

I put some debug in and pf_scrub() is being passed a NULL 'm' parameter
from pf_test(). Hand transcribed trace:

pf_scrub()+0x12
pf_test()+0x93b
ipv4_input()+0x22a
ipintr()+0x51
netintr()+0xda
softintr_dispatch()+0x5d
Xsoftnet()+0x2d

This box is my nfs server and is using the default pf.conf file as far
as I know. Also blew up on my firewall as soon as traffic started
transitting it. Same trace as far as I can see.
