I did it :

1. some wrong firmware issue message
2. very poor performance (worst than radeon with "low battery" profile),
probably reclocking issue
3. EDID issue (you have to add modeline for your screen resolution by hand)
4. Proprietary advanced stuff based on amdgpu is broken (like OpenCL not
working due to wrong vram size reporting)
5. etc.

The amdgpu driver has a very big problem: it's a driver without user. I mean,
it works almost only on APU because it's the current market for GCN 1.2, it
means it works for people who have a laptop to not do OpenCL nor Vulkan, but
people owning powerful GPU still have GCN 1.1 hardware since it's still the
market for powerful GPU.
