I've yet to see any instability after 45 minutes of exercising it, I do see a couple of messages that came out of the driver: [ 8.963389] ath11k_pci 0000:55:00.0: Unknown eventid: 0x16005 [ 11.342317] ath11k_pci 0000:55:00.0: Unknown eventid: 0x1d00a then when it associates: [ 16.718895] wlp85s0: send auth to ec:08:6b:27:01:ea (try 1/3) [ 16.722636] wlp85s0: authenticated [ 16.724150] wlp85s0: associate with ec:08:6b:27:01:ea (try 1/3) [ 16.726486] wlp85s0: RX AssocResp from ec:08:6b:27:01:ea (capab=0x411 status=0 aid=8) [ 16.738443] wlp85s0: associated [ 16.764966] IPv6: ADDRCONF(NETDEV_CHANGE): wlp85s0: link becomes ready The adapter is achieving around 500 mbps on my gigabit connection, my 2018 mbp sees around 650, so it's doing pretty well so far. Stefani - when you applied the patch that Kalle shared, which branch did you apply it to? I applied it to ath11k-qca6390-bringup and when I revert 7fef431be9c9 there is a small merge conflict I needed to resolve. I wonder if either the starting branch, or your chosen resolution are related to the instability you see (or I'm just lucky so far! :)).
