--- Comment #19 from Luya Tshimbalanga <luya at fedoraproject.org> ---
Following up this week with current patched kernel 4.9.11 from Mystro256 COPR
repository based on Alex's branch. 
The South Island part of hybrid GPU.e. Hainan and its derivative (Sun PRO) runs
smoothly without noticeable bug using via Applications "Launch with Dedicated
Graphic Card" on Gnome Shell 3.22.

Looking at the journalctl report sorted by amdgpu:
kernel: [drm:amdgpu_atombios_dp_link_train [amdgpu]] *ERROR* displayport link
status failed
kernel: [drm:amdgpu_atombios_dp_link_train [amdgpu]] *ERROR* clock recovery
failed

Not sure if that part is fixed as it does not appear affect the whole
functionality. If all South Island support works fine with amdgpu module,
perhaps will be time to enable it by default on future kernel release. If Marco
agree, perhaps this report can be closed as fixed.
Thanks for the hard work.
