[trusty] Frequently no clean shutdown or reboot

Hello,

on all of my installations of Kubuntu 14.04.x (3 PCs), frequently on a shutdown or reboot the PC powers off or reboots without umounting the filesystems and terminating the processes.

There is no message like "Terminating or killing all processes within x seconds, umounting filesystems, etc", but immediately the shutdown (power off) or reboot of the system, all via KDE. => No clean shutdown.
(No network shares are mounted.)

Next boot the fsck is recovering the filesystem/journal, etc

This behaviour occurred after the upgrade from 12.04.x to 14.04.x , this was not in 12.04.

Maybe it is a bug in upstart/systemd init scripts at reboot/shutdown.

- Reproducible with:
Download the iso image kubuntu-14.04.2-desktop-amd64.iso and install it, for instance as a Virtual Machine.

There logon in KDE and use the keyboard shortcut "ctl+alt+shift+pageup" (=Reboot) to reboot the machine several times until you can see that on the reboot/shutdown process there is no clean reboot, but an immediate reboot.

On the next boot you will see that fsck is recovering the journal (inodes cleared/recovered), etc.

Thank you for your support!

Best regards, Bernhard
