OK, this sounds like an already fixed bug.

(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=4444@....168.20.108/eth1,4444@....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 </dev/null


Thanks
