Description Stijn Tintel 2017-07-14 01:14:45 UTC

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:

Apparently nobody gives a damn. The card is where it belongs, in the trash. Together with all other QCA hardware I used to own.
