I got it working on ubuntu by downgrading the OpenCL ICD to version 16.40

Download the 16.40 driver http://support.amd.com/en-us/kb-articles/Pages/AMD-Radeon-GPU-PRO-Linux-Beta-Driver–Release-Notes.aspx
Extract the driver archive with

tar xvJf amdgpu-pro-16.40-348864.tar.xz
cd amdgpu-pro-16.40-348864
dpkg -i opencl-amdgpu-pro-icd_16.40-348864_*.deb

instructions are from here
https://github.com/genesismining/sgminer-gm/wiki/Compile-sgminer-5.5.5-in-Ubuntu-16.04.1-LTS

I think instructions could be added on readme?

It works.
amdgpu-pro-16.40-348864 is the key.
