Title:
  Systemd causing shutdown to hang

Status in systemd package in Ubuntu:
  Won't Fix

  I have Ubuntu 17.10 installed on a Dell XPS 15 using Nvidia
  proprietary drivers (384.98). The shutdown process can sometimes take
  up to ten minutes and sometimes not shutdown at all.

  I used a camera to record the shutdown messages as I couldn't see
  anything in the logs:

  wlp2s0: deauthenticating from 90:21:06:96:c2:d1 by local choice (Reason: 3=DEAUTH_LEAVING)
  systemd-shutdow: 33 output lines suppressed due to ratelimiting
  systemd-shutdown[1]: Sending SIGTERM to remaining processes...
  systemd-journald[332]: Received SIGTERM from PID 1 (systemd-shutdow).
  systemd-shutdown[1]: Sending SIGKILL to remaining processes...
  systemd-shutdown[1]: Unmounting file systems.
  systemd-shutdown[1]: Remounting '/' read-only with options 'errors=remount-ro,data=ordered'.

  systemd-shutdown[1]: Remounting '/' read-only with options 'errors=remount-ro,data=ordered'.

  kvm: exiting hardware virtualization
  psmouse serio1: Failed to disable mouse on isa0060/serio1
  reboot: Restarting system
  reboot: machine restart
  ACPI MEMORY or I/O RESET_REG.

  The major hang appears after wlp2s0 deauthenticates, and the first
  systemd-shutdow message takes up to 10 minutes to appear.

  Is this a systemd problem? What could be causing the 33 output lines
  to be suppressed?
