Hi Simon and Sven,

Thank you very much for your help.

I hope I correctly took the deaf state and 0xdeadbeef patches:
[1] https://patchwork.kernel.org/patch/9433619/
[2] https://patchwork.kernel.org/patch/9433621/

Also, I use software encryption, in the hope to avoid key cache corruption.
[3] https://patchwork.kernel.org/patch/9381651/

Are there other patches I need to apply for ar9331?

I use ath_warn() before some cases of ath9k_queue_reset(). For a distant 
node, I saw below. deaf hang comes quite often, did you observe this too?
