I've sent some fixes for this to linux-wireless on September 20, which
will make it into a new compat-wireless snapshot soon.
If you want to test them manually, look for
"[PATCH 1/5] ath9k: clean up block ack window handling"
and the two following patches on the linux-wireless list and apply those.
