New: Regression: oops when using a bridge interface with tg3
Subsystems (3)
(switched to email. Please respond via emailed reply-to-all, not via the bugzilla web interface).
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.

backtrace imageUsing a bridge interface with
- eth0 from a Tigeon3 card (Broadcom Corporation NetXtreme BCM5704 Gigabit Ethernet [14e4:1648] (rev 10))
- 3 veth interfaces from LXC
results in a kernel oops on 2.6.39. Up and until 2.6.38.7 I did not run into the issue.Unfortunately I'm only able to provide a screenshot or a part of the backtrace as I don't have a proper serial console available.

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

(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 is deprecated, guess that documentation is outdated?)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,
Bernd

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 "[email protected]/eth1,[email protected]/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
