Reporting a new bug as #196033 is for a different hw revision, and I'm seeing other things in dmesg. After reconnecting from one AP to another and back a couple of times, and a firmware crash on *every* attempt (#195987), the driver gets stuck: sylvester ~ # time iw wlan0 scan command failed: Network is down (-100) real 0m0.759s user 0m0.000s sys 0m0.003s sylvester ~ # time ip link set dev wlan0 up RTNETLINK answers: Resource temporarily unavailable real 0m7.242s user 0m0.000s sys 0m0.003s After unloading and reloading the ath10k_pci module, I am able to scan and associate again.

Can confirm problems with 4.12.8 and that it works with 4.11.8. I have Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter with opensuse Tumbleweed. Workaround is to run nmcli con up <NAME>, but it occurs too often (cca every 10 minutes).
This seems to be a bug with a newer firmware used by 4.12. See this thread for a workaround: https://bbs.archlinux.org/viewtopic.php?id=228793
Apparently nobody gives a damn. The card is where it belongs, in the trash. Together with all other QCA hardware I used to own.
