Arch Linux

Description: Since I upgraded to version 1:2.6-11 the wpa_supplicant.service failed to start on boot.
The log shows "Start operation timed out. Terminating." (see below)

Steps to reproduce:
1. only boot the system

Only known workaround:
downgrade to version 1:2.6-8

System configuration:
Dell XPS 13 9350
Intel Dual Band Wireless-8260
Cinnamon + Networkmanager Plugin
