--- Comment #6 from Paul K. Gerke (paulkgerke@craftware.nl) ---
Success! Everything seems to be fixed... "everything": 

I tried the amdstaging-kernel for 4.11.0+ and it works now! Jippieh!

This is the log for the working driver (I cut away a bit of the beginning which
is the same as for the other kernel logs):

-----------------

For anybody who wants to reproduce what I did, here the instructions which work
for ubuntu 16.04:

- git-clone the kernel at git://people.freedesktop.org/~agd5f/linux
  - checkout the branch amd-staging-4.11 
    - I specifically used commit 3e3a7c55b8de38e0557fe954f236ca8e8e925d85
- Use the config-file attached below for building the kernel
  -  The config files includes rules to bake the polaris-firmware files into
the kernel itself. I do not know if this is good or bad, but it works for me.
- Build the kernel
- install the kernel (dpkg -i)

- Follow the the not-kernel-related instructions on
https://linuxconfig.org/getting-the-rx-480-running-with-amdgpu-on-linux


Reboot, and enjoy.

I am lacking good synthetic tests for the OpenGL capabitlities at the moment,
and just tested it by running some games. glxinfo reports that amdgpu is
working, so all seems fine. I hope that this will not break again! Thanks again
for the suggestions regarding debugging @Michel, I finally chewed through it...
