That explains the apt full-upgrade problems but not the KDE/Plasma 
problems. Still, it's a start...

Thanks.

I'd left some processes running on my computer overnight. This morning 
the computer the computer had rebooted or panicked and was locked up 
with a pile of text/command line messages showing.

I reset but this morning Gnome wasn't running very well either. I'm not 
sure what the underlying problem is but after a few restarts, I'm now 
working with kernel 4.16.0-2 and Gnome over Xorg. So far it seems stable.

So perhaps the problem isn't Plasma but Wayland and it just shows a lot 
more with Plasma...
