Right. You can't stop the queue for a period longer than the watchdog timeout (default is 5s) on the device. In fact there is a bug here in that neither bcm43xx nor the softmac layer is setting trans_start. Without that the message will trigger any time when you stop the queue and the watchdog timer fires while it's stopped. So I suggest that you first of all make sure that trans_start is set. Then you need to ask yourself is this going to take a longer time than a reasonable TX timeout. If the answer is no then you're fine. Otherwise you need to do something more drastic to stop the traffic.
