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