Comment 1 for bug 1273201

That patch shouldn't be breaking the bridge though, since I'd expect it to match existing configs so as to implicitly exclude only bridges created outside NM, such as for lxc, libvirt, etc. It was definitely required in our testing.

I'd love to see the syslog message for this, and if possible with NM is debug mode. Could you attach the debugging logs for NetworkManager as you bring it up? It might help identifying the issue with this patch and fixing whatever might be wrong with it.

Thanks!
