OK some daemon isn't stopping and is using a filesystem.
Using the message you are giving me, I would do this
as root in console or konsole
# rgrep -i -l -r "unmounting file" /etc/rc.d
And find out which initscripts on shutdown are making that message
Then edit the initscript so you have a chance to see which filesystem it is
hanging on.
Or, alternatively, list out the mount points as in this example added line,
right before the unmount.
fuser -k -9 /home -k -9 /var -k -9 /usr -k -9 /
This will bring down all the processes using any of those filesystems, hard.
It is something of an extreme solution, but it may be necessary for a daemon.
More likely, it is easier to solve. A daemon needing updating or
reconfiguration is probably using /var and it should be possible to update or
reconfigure the daemon to stop gracefully. fuser is also good for listing
processes using files or sockets--man fuser for details.
