I asked a similar question on 11 July in this list, to which there was 
no real answer.

The issue has been in KDE for many years (although I don't know if its 
had the same cause all along). If you google you'll find lots of people 
asking about this.

We have quite a lot of cross-mounted disks so I always have to be 
careful when rebooting an nfs server particularly as systemd often seems 
to find some reason to wait 3 mins in the shutdown phase while a stop 
job is running.
