Title:
ath9k Unable to reset hardware; reset status -22 lead to kernel panic
Status in linux package in Ubuntu:
Incomplete
Bug description:
Trying to put the card in monitor mode on the PCEngines APU on Ubuntu
16.04.2 using Compex WLE200NX (AR9280), using ath9k. The interface is
down. Using airmon-ng to turn on monitor mode like on any mac80211
device, I get the following output (and kernel panic):
root@ubuntu:~# airmon-ng start wlp5s0
Found 1 processes that could cause trouble.
If airodump-ng, aireplay-ng or airtun-ng stops working after
a short period of time, you may want to run 'airmon-ng check kill'
