Date: Wed, 04 May 2011 14:36:09 +0300 From: Denys Fedoryshchenko <denys@...p.net.lb> To: <netdev@...r.kernel.org> Subject: 2.6.38.2, kernel panic, probably related to framentation handling Seems once more, during trying to bring another type of tunnel (this time userspace, working over tun device) and switching routes got one more kernel panic It is vanilla kernel, but many source routing rules, firewall, QoS and etc, including this tunnel now also.
