As the side note -- I have been observing similar behavior with my Atheros card when I have neighboring station with the stronger signal then one from my own. In my case, 80211debug shows that card goes into the loop, scanning all channels, it can think of. Bouncing the card cures it for a while and then it will go back into that mode.
