Public bug reported:
Per the instructions for activating an interface for use in monitor mode
provided by broadcom
(http://www.broadcom.com/docs/linux_sta/README_6.30.223.271.txt), I
execute:
echo 1 > /proc/brcm_monitor0
Nothing happens, and if I execute it with sudo privileges, the entire
system freezes. Thus, I am unable to activate the prism0 monitor mode
interface.
Research shows that this issue occurs beginning in ubuntu 13.10, but
other sources indicate it has since been patched. I am currently running
16.04 on a mac (version 10.1, Retina MBP mid 2012) with a BCM4331
network card.
