DRM - Screen black out

Hey, it's been about ten days now where my screen is going black, and it always happens twice with a few seconds difference. There is not any periodical pattern. I use F26 under Wayland, all default drivers, and the with the same GPU for years now.

Here are the logs right after it happened today again:

Aug 06 20:52:26 192.168.1.2 gnome-shell[1479]: Failed to apply DRM plane transform 0: Invalid argument
Aug 06 20:52:36 192.168.1.2 gnome-shell[1479]: Failed to apply DRM plane transform 0: Invalid argument
Aug 06 20:52:37 192.168.1.2 kernel: [drm:si_dpm_set_power_state [radeon]] *ERROR* si_restrict_performance_levels_before_switch failed

Is there a software issue or could i be facing a hardware failure and i should start looking for a new GPU soon?
