Description Joachim Breitner 2022-08-14 16:36:09 UTC

We have started seeing issues with my iwlwifi interface going away after
suspend. We get errors like these in dmesg:

[104393.142264] wlan0: deauthenticating from 4c:60:de:ea:b8:58 by local choice (Reason: 3=DEAUTH_LEAVING)
[104393.347775] iwlmei 0000:00:16.0-13280904-7792-4fcb-a1aa-5e70cbb1e865: Couldn't get ACK from CSME on HOST_GOES_DOWN message
[104393.347876] iwlmei 0000:00:16.0-13280904-7792-4fcb-a1aa-5e70cbb1e865: failed to send the SAP_ME_MSG_CHECK_SHARED_AREA message -19

And when the host comes back up, there is no connectivity. Restarting
iwd fixes the problem.

This is on a 5.17.3 kernel (Arch Linux distribution kernel), and lspci
says the WiFi device is an "Intel Corporation Wi-Fi 6 AX201".

This was originally reported by Toke Høiland-Jørgensen on the mailing list, and reproduced by me. See https://lore.kernel.org/all/f2cb9bd4fc540454ed687822e3a8dc0a5f62b352.camel@intel.com/T/#mc8f3b9652ff934c32e269a2d9e6c046ea778ab18 for the discussion so far.
