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.

This is becoming a pretty
serious issue for us. We have more that 15 local servers (both hardware and VM's)
many of which are development machines. Which means they are often rebooted or otherwise
taken off-line.
When that happens to a machine that someone has mounted an NFS share from, those with that
mount get locked up.
Can someone from KDE please chime in on why this has to be so?
We don't use Gnome or any other DE, so I don't know if this is a KDE problem or a
system problem.
