Hi,

i'm using a vanilla 3.10.43 kernel and netconsole on top of a bridge.

netconsole is used with vmbr0 (bridge) which is on top of bond0.

If i want to add another bridge to vmbr0 is fails as long as netconsole
is in use.

# brctl addif vmbr0 fwpr2004p0
can't add fwpr2004p0 to bridge vmbr0: Unknown error 524

Kernel output:
netpoll: (null): fwpr2004p0 doesn't support polling, aborting

If i do rmmod netconsole - everything is working fine again.

Greets,
Stefan
