The firmware is open nowadays for AR9271
https://github.com/qca/open-ath9k-htc-firmware/
But this is an interesting issue. I am currently working on one
problem that target becomes unresponsive(as described here
https://github.com/qca/open-ath9k-htc-firmware/issues/25) but i doubt
it's the same issue as yours. Let me see if i can reproduce your
problem. Will come back to you shortly.
