(commit : 33eb9873a283a bridge: initialize fake_rtable metrics) Could you try latest linux-2.6 tree ? By the way, if panic stills happen, could you try netconsole ? Here I just add "netconsole=3D4444@192.168.20.108/eth1,4444@192.168.20.112/00:1e:0b:ec:= c3:e4" to my boot param 192.168.20.108 is my ip addr, 192.168.20.112 the ip addr of "remote machine", 00:1e:0b:ec:c3:e4 the mac addr of "remote machine" On "remote machine" I start : netcat -l -u -p 4444
