I am afraid that it seems to be a drivers related error as neither me nor
any program that I am aware of "removes" the interface to cause this
warning. The huge problem that I have is that when I bring the interface up
(or rerun hostapd after the above warning) I usually get a kernel panic,
which strengthens my suspicion that madwifi drivers are the cause of the
trouble. 

I have currently moved to ath5k and hostapd 0.7.2, which seem to behave way
better (but it seems that I am having another problem though.. I'll
investigate and get back to the list if I don't solve it)

Cheers,
Panos
