In case this helps anyone pulling their hair out with their server or desktop crashing seemingly randomly (with no output to any /var/log files), give this a try:
nano /etc/default/grub
Add intel_idle.max_cstate=1 to the GRUB_CMDLINE_LINUX_DEFAULT line like below:
GRUB_CMDLINE_LINUX_DEFAULT="nomodeset consoleblank=0 intel_idle.max_cstate=1"
Save and exit, now run:
sudo update-grub
Reboot the device and see if it makes a difference. It sure did for me after days of troubleshooting…
