Hi Dave,
I've not been able to reproduce this yet. The attached pf.conf appears to have
been HTML-mangled, so perhaps I'm missing something in it.
The rule addition code has recently been moved to netlink, so it's not at all
impossible that I missed something there, but it'll be easier to debug if I can
reproduce it.
Failing that, if you can pass it though kgdb on your box and have that identify
the panicing line in pf_ioctl_addrule(), that might give a clue as well.
(Basically, `sudo kgdb /boot/kernel/kernel /var/crash/vmcore.last`, and then
'bt' to get a backtrace, select the pf_ioctl_addrule() frame 'frame X', and 'l'
to get the source line.)
