I wrote that I do not use grub, right? :)

All right, but when I have "amdgpu" in rc.conf it also doesn't panic, 
error or do anything stupid. I see the console output all the way through.

It's only that afterwards it doesn't work (see below). I think the 
amdgpu module loads but fails to initialize the graphics card since 
after that I don't see any other drm messages. I am getting the same 
message ([drm] amdgpu kernel modesetting enabled.) when I try to load 
amdgpu manually from the command line after the system is fully booted 
("kldload amdgpu").

After EFI loader I see the console output all the time, but after the 
last "drmn0: successfully loaded firmware image with name" I see a 
message, something about switching the framebuffer (not visible in 
dmesg) and then the screen flickers and the resolution changes. After 
that the boot continues and I see the remaining messages copied above, 
up to the login prompt.

The laptop is Dell XPS 15 2-in-1. I didn't look for similar Linux error 
messages as I assumed it's because drm-kmod isn't able to initialize the 
secondary graphics card. BTW Manjaro works fine on this laptop with full 
graphics support.
