Output of "fuser -m /dev/sda1" along with "ps auxw" taken right before the
unmounting

Version:           unspecified (using KDE 4.5.0) 
OS:                Linux

For the last couple of weeks I have been having problems unmounting the hard
disk during shutdown/reboot of my computers (3 in total). Even though it may
seem impossible to be related to the KDE software, please read below to see why
I believe so.

I am using Kubuntu 10.04.1 64-bit with KDE 4.5.0 -- system is fully up-to-date.
I have disabled plymouth in order to see what is going on during
reboot/shutdown.

Every time I reboot, I get the following messages during the shutdown process:
[...]
Unmounting weak filesystems...
mount :/ is busy
will now reboot
[...]

Upon startup, I get the following:
[...]
[    3.257417] EXT3-fs: INFO: recovery required on readonly filesystem.
[    3.257512] EXT3-fs: write access will be enabled during recovery.
[    4.299039] kjournald starting.  Commit interval 5 seconds
[    4.299140] EXT3-fs: recovery complete.
[    4.303323] EXT3-fs: mounted filesystem with ordered data mode.
[...]

which also implies that the hard disk was not unmounted properly.

After a vane long googling around, I decided to do a fresh install.

I installed from scratch Kubuntu 10.04.1 which comes by default with KDE 4.4.2.
After the installation, I restarted the system plenty of times and unmounting
was successful every single time.

I then updated to KDE 4.5.0 and the problem appeared again! The system is clean
(nothing else installed on it except for what Kubuntu comes with) and it is why
I believe it is related to KDE 4.5.0. Please also note that this problem occurs
all 3 of my computers.

In my opinion, this should be considered a major bug since it can cause data
corruption or loss.

I attach a text file containing the output of "fuser -m /dev/sda1" along with
"ps auxw" taken right before the unmounting takes place. Please let me know if
you need more information.
