Looks like ot filed to allocate tx buffer:

static struct ath_tx_buf* ath_tx_buf_alloc(struct ath_softc_tgt *sc)
{
        struct ath_tx_buf *bf = NULL;

        bf = asf_tailq_first(&sc->sc_txbuf);
        if (bf !=  NULL) {
                adf_os_mem_set(&bf->bf_state, 0, sizeof(struct
ath_buf_state));
                asf_tailq_remove(&sc->sc_txbuf, bf, bf_list);
        } else {
                adf_os_assert(0);
		^^^^^^^^^^^^^^
        }

        return  bf;
}


What is your reproduction case? WHat is your AP, wireless mode G/N? How
stable is the connection? Stable transfer rate? How about host usb
controller?

I will need more data to track it down...
