--- Comment #12 from Charly ylang-ylang@libertysurf.fr --- hi team
By installing kerenl 4.15-rc3 the blamk screen related on bug 95306 seems to be fixed, and I'm very happy for that !
the message :
[drm:hwss_wait_for_blank_complete [amdgpu]] *ERROR* DC: failed to blank crtc!
only appers when the laptop is cold (not a reboot, but a boot after it was powered off until it is cold)
The APU is a carrizo A10-8700p rev c5.
Absolutely no issue with X: I can start (xfce4) manually. I guess the error appears during mode setting. Before we got blamk screen... and now we have this message ...
