[Bug 919068] Re: bridge_ports all doesn't work at boot time

[Stéphane Graber]

I'm starting to run out of idea here...
I just tried with the following configuration Ubuntu 12.04:
 - 6 network cards
 - 3 configured as you do in your /etc/network/interfaces
 - 3 not mentioned at all in /etc/network/interfaces
 - br0 with static IP and bridge-ports all

Can you try your configuration with Ubuntu 12.04 beta1 (or later,
running updates) and ideally in a VM so we can ensure we have the exact
same setup.

I had a very quick look at ebtables, at least in 12.04 it doesn't seem
to contain a postinst, config or a debconf templates, so dpkg-
reconfigure should be a no-op here, however it does contain an init
script that could impact the system.

Result is:
