kernel reboots after a few seconds after `xset dpms force off`

Observed on at least 5.3 - 5.7 vanilla kernel releases. The kernel reboots shortly (so probably kernel panic occurs, but i can't tell since the display is off and there's no reaction to keyboard).

i915.enable_dc=0 prevents such a behavior.

00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 620 (rev 07) on 51nb X210 laptop.

The only display is attached to eDP-1.
