As stated in <a href="https://wiki.archlinux.org/index.php/AMDGPU#Selecting_the_right_driver">https://wiki.archlinux.org/index.php/AMDGPU#Selecting_the_right_driver</a> The parameters must be added to the kernel but the parameters depend on what cart you have installed in the case the card is Southern Islands **or** Sea Islands. For Southern Islands parameters are: radeon.si_support=0 amdgpu.si_support=1 For Sea Islands parameters are: radeon.cik_support=0 amdgpu.cik_support=1 but not both, or you will end with a frozen display during the boot as in my case. I hope this help others.
