--- Comment #10 from Charles (ylang-ylang@libertysurf.fr) --- Hi team,
same error in journalctl when booting archlinux with 4.15-rc3 on a HP Probook 455 G3 with Carrizo A10-8700p rev c5:
[drm:hwss_wait_for_blank_complete [amdgpu]] *ERROR* DC: failed to blank crtc!
this is not related to X (no X launched).
After a suspend resume in xfce, the sceen is a its max brightness and needs to be adjusted manualy.
(With previous kernels (4.12 4.13 4.14), the screen turned blank during a cold boot (and did not return to a correct state after).
