    Default Kernel 5.2.8 nl80211: Driver does not support authentication/association or connect commands

    After upgrading to 5.2.8 to the following error occurs:

    1566065093.840954: Successfully initialized wpa_supplicant
    1566065093.849877: Could not read interface wlan0 flags: No such device
    1566065093.849909: nl80211: Driver does not support authentication/association or connect commands
    1566065093.849912: nl80211: deinit ifname=wlan0 disabled_11b_rates=0
    1566065093.852333: Could not read interface wlan0 flags: No such device
    Some findings:

    • Starting wpa_supplicant during boot of 5.2.7 works.
    • Starting wpa_supplicant during boot of 5.2.8 fails.
    • Restarting wpa_supplicant under 5.2.8 always succeeds.

    Any idea?

    Digged deeper, but found no obvious reason why wpa_supplicant would die. Added Restart=on-failure to section [Service] :

    Code:
    erlangen:~ # journalctl -b -u wpa_supplicant-lan.service -o short-monotonic
