Public bug reported:
Steps to reproduce below but it doesn't happen all the time:
nmcli set wlan0 managed no
ifconfig wlan0 down
iwconfig wlan0 mode monitor
ifconfig wlan0 up
[packet capture on wlan0]
ifconfig wlan0 down
iwconfig wlan0 mode managed
airmon-ng start wlan0
[packet capture on wlan0mon]
airmon-ng stop wlan0
ifconfig wlan0 down
ifconfig wlan0 mode managed
nmcli set wlan0 managed yes
After that network managed didn't take back the device and iwconfig displayed
something unrealistic hube in txpower - like -13124245424dBm
along with stacktrace in dmesg:
