Maybe it is not related, maybe it is..... I tried to use an Atheros AR938x card in AP mode on FreeBSD 10.3, r302295 and 11.0, r297415 for quite some time now. Of course I got the ``ath0: stuck beacon; resetting (bmiss count 4)`` over and over again. Beside this, I also observed the following messages: Jul 12 11:15:47 kwik kernel: ath0: ath_edma_tx_processq: Q3: empty? Jul 12 11:15:47 kwik kernel: ath0: ath_edma_tx_processq: Q3: empty?
