FreeBSD-current of about a week ago (2.0-BUILT-19950617), with XFree86 3.1.1; kernel ppp driver with pppd 2.1.2; single ppp0 interface (modem on ttyd1), no ethernet interfaces. >Description: I've experienced a system hang (no console response) a couple of times now, and I think the circumstances were the same.
