  Shutdown"
I think i have a specification to this issue.

First, my system with the same problem at shutdown/reboot, but only in a
very special case:

Fresh install of Ubuntu Server 16.04.2 LTS
CPU: Intel Xeon E3-1245v6 (Kabylake)
Mainboard: MSI C236A Workstation/Server Mainboard (model: 7998-012R; latest BIOS: v2.7)
RAM: 4x TRANSCEND 8GB DDR4 2133 ECC-DIMM 2Rx8 1Gx72 288P 512Mx8/CL15 (model: TS1GLH72V1H)
SSD: 2x Samsung Basic MZ-7KE256BW 850 Pro interne SSD 256GB
HDD: 2x Western Digital Red 4TB NAS (model: WDBMMA0040HNC-ERSN)

Description of the special case with the shutdown/reboot issue:

The problem only reveals when RAID-Mode auf the MSI Mainboard is
enabled. After resetting to AHCI-Mode, the problem is over an the server
works fine. It seems, that's a problem with the "Intel® C236 Chipset" or
more specific a driver problem with intel based components on the
different systems.

Title:
  [Xenial] shutdown/reboot hangs at "Reached target Shutdown"

Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  I tried getting more information in the debug-shell but I was
  unsuccessful in doing so. I was able to switch to the debug shell via
  ctrl+alt+f9 but I couldn't actually type anything in. I could switch
  back to the stuck shutdown screen via ctrl+alt+f1, and hitting NumLock
  would turn the light on my keyboard on and off, but I couldn't do
  anything else. I captured a journal of the stuck reboot.
  Interestingly, the journal shows a few more lines after "Reached
  target Shutdown", which is as far as I get on my screen.

  This system was installed with Xenial 16.04.1 (never been upgraded)
  and has had this problem since the very first boot.
