OK, so grub (believes it) is installed correctly.

So grub-update hung while generating the config file. Let's assume the
worst-case scenario that the config file is partially written and so is

Oh, this is during the shutdown phase? This isn't (necessarily) a
problem. This implies to me that you're using watchdog software
(possibly from the watchdog package). When the watchdog service stops,
it closes the watchdog device. The message above is just a warning
saying "I've noticed that you've closed the watchdog device, but the
countdown timer is still running". Now, if you're restarting the
watchdog service that's not a problem, as you'll write to the device
before the timeout; during normal shutdown it should also not be a
problem as the watchdog should stop close enough to the actual
shutdown/reboot that the watchdog won't fire.

So, in other words, something else is causing you problems. Check your
logs. Watch the console (if you can), for any services which are holding
back the shutdown.

One thing that has struck me as a possible issue. How old was the system
before the update? Is it possible that you've upgraded a stable Wheezy
system to a stable Jessie system? If so, please read the Release Notes
for Jessie for any gotchas.
