Amdgpu Segmentation fault

I'm struggling to get my fresh Ubuntu installation (16.04.3 LTS) working with amdgpu-pro. I have a NVIDIA gpu installed at PCI port 1 for which I haven't installed any drivers. My screen is connected to that card. Now I've installed an AMD RX 470 card to PCI port 2 and installed the amdgpu package following the installation instructions provided here: Installation Instructions for amdgpu Pro / amdgpu All Open Graphics Stacks .


Sadly after a reboot Xorg doesn't start anymore. I'm getting the following error message:

I've googled a lot and found many similar issues but none of the threads provided an answer on how to fix this. Can someone help me out? Thank you!!!
