Just some more information to share here. I gave it another try, and the
console  freezes exactly at the moment when drm enables the kernel modesetting. 
[    6.329371] [drm] amdgpu kernel modesetting enabled.
With nomodesetting it works like it should, the vgaconsole remain active and
useable.
Do we know somebody who has some knowledge to understand the DRM logs?
Otherwise these lines are pretty strange for me:
[    6.330490] amdgpu: Ignoring ACPI CRAT on non-APU system
