I am running Ubuntu 18.04 on an AMD Phenom(tm) II X4 945 Processor, 8Gig of

There is some sort of bug in the version of KiCaD I have
(4.0.7+dfsg1-1ubuntu2) with its pcbnew program that puts my machine in a state
where I have to use the "magic" SysRq key to forceably reboot it (I can ssh in
from another computer, but /sbin/reboot does not work).
Judging by the messages it looks like a lockup in a video card.
Do other 3d programs run fine ? Try a 3d-game like quake or similar.
Try turning off the compositor. Also keep in eye on the fan and GPU
temperature.
It could be a bug in the driver, but nouveau worked quite well for me on
both 18.04 and 20.04 for many years.

I've included the last of the kernel log. It looks like something is broken
in nouveau, which I am guessing has something to do with the video somehow.
(And no, I am not going to download and install NVIDIA's video driver.)
I don't know if this is a kernel problem (I current have kernel
4.15.0-187-generic), or something in X Server.
