--- Comment #2 from Russell Haley <russ.ha...@gmail.com> ---
I've been digging into the code for if_bridge.c, which is found under
sys/net. bridge_broadcast only has one call to m_dup on line 2553.
mc = m_dup(m, M_NOWAIT);
if (mc == NULL) {
if_inc_counter(sc->sc_ifp, IFCOUNTER_OERRORS, 1);
continue;
}
This is just a guess: I'm wondering if the M_NOWAIT is causing the
panic because... er... "someone has a sleep lock they shouldn't"? I
don't really know what I'm talking about though (a little bit of
knowledge...).
I guess I'd have to try and correlate to some sort of lock begin held
in the adapter specific code?
