Julien and Peter,

I got no errors or messages form dmesg saying that some blobs
are missed.
I got some console messsages written in an very big font-
So I compiled the the kernel again with AMDGPU=y this time
and now I got  all the messages of the kernel boot
in normal fonts (my screen is 3840x2160).

The only suspicious lines are

It seems I made a step forward  and I will try to get get X11 up next.

Thanks to all of you for your help
