Note
When using AMDGPU, it is recommended to unset the ATI Radeon option so that the radeon module is not built. Or alternatively, the module can be built and blacklisted (after rebooting check with lsmod | grep radeon to see if the blacklisting worked). The amdgpu and radeon modules are not meant to be loaded simultaneously, unless, for example multiseat, system requires it.
