Bug Description
After "waking" (shaking my mouse) to revive the display server my machine was usable for about 1 minute after the wake. Then all of the sudden all of my USB devices lost power completely, my hard drives stopped spinning and the system was at a stand still. Reading into the log files I find that the last thing the system did before it died. It was in the process of a "dhcp4 change". I would also like to mention I was running 3 VNC server sessions at the same time, but none of the viewers were active. I also confirmed that the power supply is defiantly not the reason its a 1000 watt platinum PSU that is under a year old and the system was usable again after a reboot.
I am using Kernel version 4.11.7 built from the mainline with the Ubuntu configuration. There were no custom modules loaded (nothing outside of the 16.04.2 repo)
here is the log /var/log/syslog
