I faced the problem via another reported bug for Gajim which tries to read teh
/proc files on startup.
The workaround for the Gajim issue was by restricting access to root as
suggested in above bug description.
My affected system is an Acer One 722 with Ubuntu Mate 16.04.

Reading from /proc/brcm_monitor0 causes lockup of CPU
Status in bcmwl package in Ubuntu:
Steps to reproduce:
Install and use bcmwl-kernel-source
$ cat /proc/brcm_monitor0
Watchdog detected hard LOCKUP on cpu 1
Tested on Trusty and Vivid.
The file is readable by everyone. At least change this to only root.
