Subject: Bridged networking panics

Hi all,

i'm attaching 3 panics of a 3.2.X kernel.
The panics were obtained with a 3.2.20 from debian testing and from a 
vanilla compile of 3.2.21.

Those panics have been already posted some months ago [1] but are not fixed.

The problems seems related to bridged networking.
Whenever there is a bridged aliased interface (like br0:1 br0:2 etcc), 
the server will panic after some time. The more the network load, the 
shortest the uptime.
Removing (ifconfig br0:1 down) or adding back an interface seems to help 
the panic to appear.

Any more hints ?

MC
