Same issue, since upgrade to 16.04 the system has hung during reboot. The network isn't fully shutdown and responds to pings but sshd is stopped, the system reboots successfully if swap is disabled. Attempted to add reboot=force to grub, to no avail; only disabling swap fixed the issue.

I have finally collected shutdown info using vt9. Issues collecting info due to what I believe is a timeout where vt9 is not activated when ctl+alt+F9 is pressed. I was able to collect info in vt9 to file "shutdown.text" I appended outputs to file "shutdown.text" the following commands in this order: systemctl list-jobs >>shutdown.text systemctl --failed >>shutdown.text uname -a >>shutdown.text systemd --version >>shutdown.text lsblk >>shutdown.text blkid >>shutdown.text journalctl -b >>shutdown.text systemctl -all >>shutdown.text journalctl -xe >>shutdown.text After gaining these data I was only able to finish the reboot with the alt+Sysrq and REISUB which forces a reboot even when I just want to shutdown Each output I separated upon next boot by hand with a line ######################### for easier perusing. As a workaround for shutdown/reboot I turn swap off, 'sudo swapoff -a && systemctl poweroff' or 'sudo swapoff -a && reboot' which occasionally fails if SWAP has more data than available RAM. In that latter case I am left waiting for the hang and then using alt+Sysrq+REISUB to reboot then shutdown again immediately upon boot before SWAP has a chance to gain data, then I can use any form of halt, poweroff or menu to shutdown. I have been unable to get answers from AskUbuntu or the above listed bug #1464917 "Reached target Shutdown" I am filing this bug per instructions requested in that bug. Other systemd bugs I have researched #788303 Debian bug reports, #2930 Github and #3087 Github. Thanks for your time and efforts to help with this issue.
