Title:
USB unplug crashes system - Assuming host is dying, halting host
Status in linux package in Ubuntu:
Incomplete
Bug description:
Occasionally, when I unplug my Android phone (connected over USB), my machine
crashes.
At first, I presumed the entire machine had halted since the keyboard and
mouse stopped working.
However, I'm still able to SSH in although the screen is completely
non-responsive. Pressing the power button on the CPU seems to bring up a window
with Ubuntu's power options.
My Ubuntu version:
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.4 LTS
Release: 14.04
Codename: trusty
Kernel version:
Linux nixentor 3.13.0-91-generic #138-Ubuntu SMP Fri Jun 24 17:00:34 UTC 2016

I see the following output on dmesg:
