Sorry, I misunderstood what you were saying before.  Can you try and
see where the packets are getting lost or improperly handled by
running tcpdump on the various interfaces?  For example, check that
packets are coming in with tags on the physical interfaces, have tags
on the bridge interface, no tag on the vlan interface, etc.
