Not first...but I just recompiled the kernel without BRIDGE_IPF.
Still same result, wm1 seems to seize. Here's a little more console
diagnostics...with mildly sanitized ethernet addresses.

# brconfig -a
bridge0: flags=41<UP,RUNNING>
        Configuration:
                priority 32768 hellotime 2 fwddelay 15 maxage 20

        Interfaces:
                tap0 flags=3<LEARNING,DISCOVER>
                        port 5 priority 128
                wm1 flags=3<LEARNING,DISCOVER>
                        port 2 priority 128
        Address cache (max cache: 100, timeout: 1200):

                xx:e0:18:db:yy:3d wm1 600 flags=0<>
[NOTE: adding and deleting tap0 has no functional effect]

tcpdump on the console shows a fair amount of traffic on wm1 (?!)
I'm not very familiar with tcpdump, but I used:
# tcpdump -i wm1 -lq
Packets seem to be flowing to/from several hosts on my network
UDP packets report lengths != 0
all tcp packet lines end in tcp 0 (means zero length?)

Anything else to try?
