We need to know the LOR before anyone can tell what is going wrong ;-)
Ask and you will receive:
lock order reversal:
1st 0xc077a440 pf task mtx (pf task mtx) @
/usr/src/sys/contrib/pf/net/pf.c:6331
2nd 0xc07d3fac tcp (tcp) @ /usr/src/sys/contrib/pf/net/pf.c:2719
From pf.conf(5):
BUGS
Due to a lock order reversal (LOR) with the socket layer, the use of the
group and user filter parameter in conjuction with a Giant-free netstack
can result in a deadlock. If you have to use group or user you must set
debug.mpsafenet to ``0'' from the loader(8), for the moment. This work-
around will still produce the LOR, but Giant will protect from the dead-
lock.
though this is known and there are already other similar LORs (like
#17, ...) I added it to the LOR page with ID 191 because it's another
code path in the backtrace. That way people will also find this one.
