Title:
  Total system lockup on power cable connect/disconnect

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I've had this issue for six months or more, though it is fairly
  infrequent. My laptop (Dell Latitude E4300) will lock up entirely
  (keyboard and mouse not functioning, not responding to pings or sshd,
  I'm left with whatever image was last on the screen, frozen) sometimes
  when the power cable is plugged in or unplugged. I'd say it's maybe 1
  in 15 times, but today it happened twice in a row and so it's finally
  time to try to solve it. I have to hold down the power button to power
  down and reboot when this happens, sometimes losing some work.

  I'm not sure if my kern.log is being uploaded with this (I'll add it
  afterwards if I don't see it) but the last two restarts were both
  manual because of such lockups. I don't see any useful errors before
  the first [0.00000] lines (May 4, 17:25:41 and 17:27:12), though.

  I googled around and one suggestion was to remove the jupiter package.
  That was not installed. I'm not sure where to go from here given that
  there's nothing useful I can find in the error logs.
