Comme= nt # 20 on bug 10517= 7 from Reimar Imhof 
I've tried drm-next-4.17-wip.
What I've seen is the same as described with the initial bug description:
When monitor is connected via hdmi I get wrong colors. This appears during =
boot
before the gui (x.org) gets started (frame buffer boot animation). Wrong co=
lors
(sort of violet instead of black) also appear on frame buffer text console =
and
with x.org gui.
This bug appears with "amdgpu.dc=3D1" kernel parameter.
While running x.org I've turned the monitor off and on again. This gives
correct colors but the screen resolution goes to 1024x768. So it's no work
around.

What I've seen is: The colors are correct if I run the monitor with a yuv c=
olor
model instead of rgb.

One thing seems to be better: Every boot manged to get to the graphical log=
in.
I've tried about 10 reboots.
