umount fails on reboot/shutdown.

On openSUSE 11.1 with KDE 3.5 I noticed that it did not successfully umount /var, /home and /usr upon reboot or shutdown.

I'm getting error such as: umount: /dev/sda9 busy

I edited /etc/rc.d/boot.localfs and entered lsof > /var/log/openfiles.txt after the line "if test "$UMOUNT_FAILED" = true -a -z "$mtab" ; then" to figure out what files were open.

I found that the programs console-kit-daemon, pulseaudio and dcopserve were still running.

I then entered the following before the umount lines:

killall -q -TERM console-kit-daemon
killall -q -TERM pulseaudio
killall -q -TERM dcopserve
sleep 1
killall -q -KILL console-kit-daemon
killall -q -KILL pulseaudio
killall -q -KILL dcopserve

It now successfully umount's all filesystems, but why are these programs still running, is it known problems or something wrong with my configuration?

Here is the disk partitions:

Those processes all look like things that might be started by a local X session. They are daemons in the traditional Unix sense, but on the other hand, they are related to your session.

Exactly how did you perform the shutdown?
Did you use the "shutdown" command from the command line? If so, try using the shutdown button in the KDE logout dialog instead. (If the shutdown button is not displayed by default, adjust the KDE settings in the KDE Control Center).

When you use the shutdown button in the KDE logout dialog, KDE will first log you out, ending all the processes started for your session, and only then initates the shutdown. This should make sure all the "session-specific daemons" are stopped properly.

I used the shutdown from KDE, I've also tried to logout to console and then shutdown. And I've tried to set the runlevel to 3 and not start X at all, atleast one of those programs are running also without starting X/KDE.
