Oh, thanks! Hmm.. There was a ton of changes between 20150424 and 20150511. For one, ath10k started to use chanctx API and FAST_XMIT. But it's not a given these two are to blame. The latter can be easily disabled by removing IEEE80211_HW_SUPPORT_FAST_XMIT from ar->hw->flags in ath10k's mac.c. The former.. not so easy. I'd be awesome if you could do a git bisect. The commit ids are a3da0fb6(good) f17107c(bad) (you need linux-next git repo including its tags for these ids to be resolvable).
