--- Comment #24 from Adrian Garay adrian.garay@outlook.com --- Since I didn't clearly specify above, my result was with amd-staging-drm-next, but the behavior is identical to the current 5.0 release. When the screen goes blank the machine stops responding, but it appears systemd still periodically logs work such as cron jobs. Laptop has to be hard powered down by holding the power switch.
