I can't reproduce this problem here so I'll need your help to
track it down.
Can you see if you can relate the lock-ups to specific events
such as a particular packet being sent through the bridge?
If we can recreate the problem on demand that that helps us to
find the root cause.
You mentioned that you took packet dumps on the system. If you
can show us the packets through the bridge and its ports when
the problem occurs that would be great.
