--- Comment #10 from Charles (ylang-ylang at 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).
