Hi,
updated the kernel on my test laptop and noticed that now iwlwifi
crashes every time during boot. This is with tag ath-201701271935
ath.git master branch, which essentially is wt-2017-01-27 from
wireless-testing plus latest ath patches.
I tried v4.10-rc5 and iwlwifi didn't crash so my guess is that this is a
regression in the latest iwlwifi pull. Below is the crash log and the
location in source. This is all I got via netconsole.
