[Bridge] STP Loop not blocking

The setup is as follows
ixp4xx #1: br0 (eth0, eth1, ath0, ath1) STP enabled
ixp4xx #2: br0 (eth0, eth1, ath0, ath1) STP enabled
with 2.6.16 one of the interfaces goes to blocking and the other is left to=
forward. In 2.6.18 the interfaces always stay forwarding.

Since you haven't give much detail on your setup (is stp enabled on both =
bridges, for example), I'm not 100% clear what may be happening. But it =
does sound like something I ran into before.
