I suspect the real cause of the issue is something else though, like the probe request not going out properly or the card being in a kind of 'temporary lock-up' state where it's not really doing anything for the time being -- I've never had a problem on any other (than iwlwifi) hardware. Of course, the virtual STA device support stuff potentially has similar issues, especially if it does channel switching like the ath9k virtual wiphy stuff. johannes
