Changes

- ** Edit /etc/default/grub as root, for example: sudo nano /etc/default/grub- ** Add intel_idle.max_cstate=4, it should look like this: GRUB_CMDLINE_LINUX="intel_idle.max_cstate=4" - ** Save the file and close the editor- ** Run sudo update-grub2 to regenerate the grub config files

'''Note:''' If you need to boot from LiveUSB you will need to add "intel_idle.max_cstate=4" to the kernel boot line manually.
