dmesg-output

About once a day the GUI freezes. Mouse is still moving but further nothing.
Logging in through ssh succeeds, though. (Restarting GDM leads to some
flickering, and then an even more frozen system)

Dmesg-log is attached, it's a Fedora system using Wayland, but it also
occurs
on Xorg.

Nouveau version:
xorg-x11-drv-nouveau-1.0.15-3.fc27.x86_64

BUG in nouveau_mem_host. I think we've seen that before. Not sure at what
point
(and whether) it was fully fixed.

I'm the same problem Nouveau or nVidia divers. Currently, I use Nouveau
because
the freezes are less frequent.

I'm on Kubuntu 18.04 (install by Live CD).
