Could the ath driver corrupt memory if the TX DMA cannot be stopped?
Yes, this is why we have had a series of patches to address this upstream,
the latest one was for RX DMA failing to stop but Felix found a fix for that.
Apart from that I am not aware of more issues. Can you please try with
wireless-testing.git ?
