Unfortunately, not really. I can see you are hitting PASSIVE_NO_RX,
meaning that the uCode complains that you are trying to Tx on a
passive channel on which it hasn't heard any beacon yet. But then we
finally get a beacon there, and open the queue again.

Anyway, can you try the attached patch ?
Note that I have no real way to test it (I have to admit I haven't
even compiled... I am not in my office).
I hope it might help.
