Title:
nm-dispatcher caused kernel crash.
Status in network-manager package in Ubuntu:
Confirmed
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
