Sorry, don't see those messages.  I guess I'll have to reboot with
'debug' to see that.

Before I do that, I booted this time with the RFKILL switch set to
kill the radio (both BT and WIFI), and reran the above tests.

Here is what 'ip monitor' said:

[root@...ndon ~]# ip monitor

ff02::fb via ff02::fb dev eth0  metric 0
    cache
192.168.2.1 dev eth0 lladdr 00:1c:df:e2:3e:e9 STALE

Here is what 'inotail -f /var/log/messages' said:

Aug  5 06:12:22 tlondon mtp-probe: bus: 3, device: 2 was not an MTP device

So, no WARN_ON messages.

I'd like to conclude that this is due to UDP casting on the wlan.
I'll reboot with the radio on and in debug mode to see what happens.
