Daily crashes from Linux Server (Proxmox) and Intel CPUs

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…
