Comment:
You could perhaps search a a `linux5.1-5.1.x` kernel's `dmesg` output for amdgpu command line suggestions:
```
sudo dmesg | grep amdgpu
```
I don't know whether you could or should specify a module option for `amdgpu.si_support` or `amdgpu.cik_support`. Source: [Arch Linux wiki](https://wiki.archlinux.org/index.php/AMDGPU) where some more hints can be found also.
