--- Comment #3 from Paul K. Gerke (paulkgerke@craftware.nl) ---
Ah, thank you! 

Really quick @Michel Dänzer:"Sounds like maybe some files under
/lib/firmware/amdgpu/ are missing in the initrd":

I thought the same, so I baked the important firmware blobs right into the
kernel, just in case there would be some issues. I will dig up the settings
that I used tonight when I have some more time.



Anyway, the other tip allowed me to extract the (Crash) logs using my serial
console. The machine freezes up just as usual after modprobing. I did the
following:

- Boot with: linux /vmlinuz... root=UUID=xxxx ro debug ignore_loglevel
modprobe.blacklist=amdgpu console=ttyUSB0,115200
- (I disabled all X-server functionality before so that it would not screw with
any graphics settings)
- I logged in and issued "sudo modprobe amdgpu", as suggested.
- I recorded the following logs on my second system.

- I spot a "Something is broken", so something seems fishy.

- Note: I do not have time right now to process the log since I have to go to
work.
