Hi John, I merged wireless-testing master with our main development branch and got a hanging system. So I tested your master branch after that and the same result. Given the kernel log it may be the commit mentioned below although I did not bisect it yet. 077a91548 mac80211: support adding IV-room in the skb for CCMP keys Our driver does not do hardware encryption so not sure whether it is related.
