Manjaro installation - Ryzen Pro - not still full supported

first a little addition: I tested the two settings for iommu more extensively and cannot see a difference any more as reported in my last post.
So, set to soft shows the same behavior as pt does. pt showed right now a distorted screen / screen tearing and then restarted itself instead of just getting stuck.


Here the report of inxi -Fza

Regarding the hw-probe: I’m just working on it. It’s a bit tricky since I can’t get wifi access any more.
