A second, more severe manifestation of what looks like the same broken display/backlight control path was reported as bug #2161271: after resume from S3 on 7.0.0-28 the eDP panel stays completely black (system alive, no i915 re-init messages in the journal, hard reset required). On 6.17.0-40 both brightness control and suspend/resume work fine on the same system. Also filed bug #2161272 (unrelated nvidia module load WARN on the same kernel).
