Problem solved :).

As stated in
https://wiki.archlinux.org/index.php/AMDGPU#Selecting_the_right_driver

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.
