This makes me suspect an effect of bug #221631. Although the dbus package
in oneiric includes a fix for this bug, since the dbus service can't be
restarted, the old stop condition is in effect for the job at the time of
the post-upgrade reboot, with the result that dbus shuts down as soon as
'runlevel 6' triggers, and if you use Network Manager, your cifs filesystems
will not cleanly unmount.

However, the behavior seen here is a timeout of the mount after 300 seconds
and a forced unmount, so I don't know why these would have blocked a clean
unmount in your case.

Do you often see errors on this machine at reboot about filesystems not
being cleanly unmounted?

Apologies if I've already asked this question, but is /etc/init.d/umountroot
an unmodified conffile? (i.e., does 'debsums -s -e initscripts' return
warnings, and what does 'ls -l /etc/init.d/umountroot*' show?)

What is the output of ls -l /etc/rc6.d/ on this system?

It may come to this, but that's easier said than done. The risks of doing
it here include hanging the system on boot (potentially very bad if it's
remotely managed), and filesystem corruption due to an unclean shutdown. We
do want to resolve this bug, but we shouldn't be hasty to change things that
might make it worse.
