--- Comment #61 from Jan <jv1 at home.nl> ---
Last two days I performed various tests to get a better understanding of the
root-cause. First I kept the machine switched on a full night with the settings
i915.modeset=1, nouveau.modeset=0. Dmesg showed no failed hardware. In the
morning the machine had crashed, ssh-server down. I can't see any errors in
dmesg.

I subsequently repeated with recovery mode. First booting until the login
screen: crashed. Then by booting to the recovery console: crash. 

After every test I reboot by pressing the power-key. The tests show that the
machine crashes within a few minutes when keeping the machine on for a long
time.

I also tested by keeping the machine in the GRUB menu. The machine has not
crashed then. The machine also does nog crash by using Windows 10. Kept the
machine on for a full day.

In my opinion the above rules out any hardware malfunction. The issue occurs by
loading the linux in the current configuration.

Since my machine also has a nvidia 940mx card on board, I am now planning to
install the nvidia driver from the nvidia site :
'NVIDIA-Linux-x86_64-340.96.run'. Wonder what's gonna happen then.

I am also planning to see if I can enhance debugging to see if I can get any
logging on the error.


ps: with all due respect, I am somewhat annoyed that there isn't any response
on my previous posts. Currently I am typing in the void, while many messages on
this topic have been posted in this thread. At least replying would be nice :-)
