https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D221845 --- Comment #2 from Russell Haley <russ.haley@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 =3D m_dup(m, M_NOWAIT); if (mc =3D=3D 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? --=20 You are receiving this mail because: You are the assignee for the bug.=
