Full /var/log/messages from iwm panic.

I tried to attach to an open of several open networks at "BornHack" yesterday
and only managed to panic the iwm driver repeatedly.

I belive the AP's were Ubiquity, and I can probably get hold of the people who
runs them if need be.

I have attached the full /var/log/messages as attachment, but here are what I
guess is the top-level info:
