kernel 4.8.4 kills Wi-Fi

Not able to connect to Wi-Fi AP after upgrading the kernel to version 4.8.4. Version 4.8.2 is working fine for me.
Please see journalctl logs below.

Re: kernel 4.8.4 kills Wi-Fi

Versions of your driver, NM, wpa_supplicant, etc?

Arch + dwm   •   Mercurial repos  •   Surfraw

Re: kernel 4.8.4 kills Wi-Fi

All components were installed from official repos and are up-to-date: networkmanager 1.4.2-1, wpa_supplicant 1:2.6-1.
How do I know wi-fi driver version? I guess (from the log) it's called iwlwifi and comes with the kernel.
My system is 64-bit.
