Send a large UDP packet through the bridge. I believe the problem is the ip_fragment code is not taking into account the VLAN header that needs to be added to the packet when it gets fragmented on the way out. Just send the large UDP packet through the bridge. I use ttcp. If it panics then I can send you the fix. There are further changed to ip_output.c
