Title:
  Computer hangs on reboot or shutdown, typically for >10 mins, Ubuntu
  16.04 and previous versions

Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  I am aware of the thread here:

  https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1464917

  People there are asking that if you have the same/similar bug to
  report it separately, so that's what I'm doing.

  What I've noticed is that my shutdown process hangs as some point,
  usually with the screen being black or with a single cursor.  After
  >10 mins, the computer will finally shut off.  I've had this issue I
  think since 15.04, definitely in 15.10, and now still in 16.04.

  I've tried the fix

  $ sudo systemctl reboot

  which worked one time, but not another time.

  I've also tried

  $ sudo swapoff -a sudo systemctl reboot

  and that appeared to work, but I haven't tested it enough times to say
  it always works.  For what it's worth, turning off the swap probably
  took longer than my typical black screen shutdown so it's really not a
  stopgap fix either way.

  I know this isn't enough information to be sure I'm having the
  swap/systemd failure, so let me know what else you need.  Thanks.
