Re: kern/133902: [tun] Killing tun0 iface ssh tunnel causes Panic String: page fault
This pr is duplicate of kern/116837 so I think we can close it. The problem is fixed in CURRENT and 8-STABLE and there is a patch for 7-STABLE (see kern/116837 for details). -- Mikolaj Golub ___ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to freebsd-net-unsubscr...@freebsd.org
