I did check other bug with the same message, but they don't seem to be about wlan, while the critical line here is:

CRDA: Error: command ['iw', 'reg', 'get'] failed with exit code 1: nl80211 not found.
I guess. I get the crash every few seconds it seems, but wlan continues to work. Feel free to dupe or close if you consider this invalid.

Hi spaetz,

The warning reported here typically indicates that it took longer for your system to resume from suspend than expected. I believe there is a 5 sec barrier which your system likely exceeded. Based on your dmesg output I see PM: resume devices took 20.110 seconds. I'm setting this to traiged for further investigation. Thanks!
