Dear all, turns out, my system was suffering from completely different
bug with similar symptoms. It was a problem with the motherboard BIOS. I
upgraded the BIOS and the bug went away. I'm taking myself off the
mailing list for this bug.
If you're suffering from a similar issue even after the fix in Xenial,
try upgrading your BIOS. If that doesn't help and you're on a desktop,
try clearing CMOS with the jumper (not through the menu) after the
successful BIOS upgrade.

reboot hangs at 'Reached target Shutdown'

This bug is resolved. Do not follow up to this bug. Shutdown bugs
are specific to the software installed and its configuration. If you
are experiencing a shutdown hang, please file a separate bug report
and follow the debugging instructions described in the "Debugging
boot/shutdown problems" section of
/usr/share/doc/systemd/README.Debian.gz to check if there are any
hanging jobs at shutdown. Capturing a screen photo of "journalctl -b"
in the rescue shell might be enlightening.
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
