That's the sort of behaviour I would expect if you had duplicate MAC
addresses or other ARP related problems. Does a ping also give you
similar behaviour?
When you do 'brctl showmacs <name of bridge device>' do the MAC
addresses match against the number of the port as listed by 'brctl
show'? (I think port numbers are 1 based).
