Now I can reproduce it persistent.
Kernel panic on a network bridge with a msk interface hasn't connection.

Do I need open a new bug? Or it can be fixed easy?
The main reason is:
msk0: watchdog timeout
from source:

void
msk_watchdog(struct ifnet *ifp)
{
[...]
			/* XXX Resets both ports; we shouldn't do that. */
			msk_reset(sc_if->sk_softc);
			msk_init(ifp);
[...]
}
