--- Comment #3 from Imre Deak <imre.deak at intel.com> ---
Did you try if limiting CPU C states also gets rid of the problem (leaving
graphics power saving enabled)? If using intel_idle you can boot with the

intel_idle.max_cstate=1

kernel parameter to do this.

Could you provide a dmesg log booting with drm.debug=0xe?

Did you try to collect logs after the freeze?:
- via ssh if it still works
- net or serial console if the machine has a serial/ethernet plug (for
netconsole https://wiki.archlinux.org/index.php/Netconsole)
- using pstore, having EFI or RAM based pstore, hard and soft lockup detection
enabled in your kconfig and booting with "nmi_watchdog=panic panic=5" kernel
parameters.
