2.6.38->2.6.39 regression, appears to be bridge-related. There's a
partial screencap of the oops linked below.
Bernd, it would be helpful if you could set the screen to more rows
(50?) and then retake that photo. Documentation/svga.txt might help
out. Thanks.

The oops happens as soon as I add the lxc veth interface to the bridge, before
everything works as expected.
A new, full screenshot is attached
https://bugzilla.kernel.org/attachment.cgi?id=59732
(For yet unknows reasons I can't access the serial port redirection via ssh and
I won't be able to attach a real serial port cable before Monday, so I'm afraid
you have to work with the screenshot for now.)

(the kernel says that vga=... is deprecated, guess that documentation is outdated?)
Thanks and cheers,

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@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 </dev/null
Thanks
