Ryzen + RX 580 only one device working

Hi,

with the intent of improving the quality of my hashcat testing I switched to a Ubuntu 18.04 LTS workstation.
Situation hasn't changed.
Fresh OS install/update/upgrade, Installed hashcat (git clone for last version) rocm-dkms and Intel OpenCL runtime.
Hashcat pmkid benchmark is the same: around 220kH/s for the GPU and around 5kH/s for the CPU.
Maybe there's something I should do after installing the Intel runtime (i followed this: https://gist.github.com/Brainiarc7/1d13c...c83cd973d5 )?

hashcat (v5.1.0-42-g471a8ccc) starting in benchmark mode...
