[Bug 1464917] Re: reboot hangs at 'Reached target Shutdown'

[Mario Limonciello]

I've definitely reproduced this as recently as today on a real machine on
16.04 (fully up to date) with similar symptoms described as reaching the
shutdown target and then just hanging for a while.

I also uses sysrq to recover at that point.

I've also noticed this in Virtualbox, particularly after installation is
complete that it won't reboot.

  reboot hangs at 'Reached target Shutdown'

Bug description:
  I rebooted my 15.04 system, and found it hanging indefinitely at the
  plymouth shutdown screen.  Hitting esc to reveal the console showed a
  normal set of shutdown messages, ending with 'Reached target Shutdown'
  (paraphrased from memory).

  The system never rebooted on its own.  I had to use SysRq to finish
  the shutdown.
