<pre wrap="">Hi all,
My Ryzen stuff finally arrived, so I can help get GPU Passthrough working.
My CPU is the 1800X and my motherboard is the Asus Prime X370-Pro.
I'm on kernel 4.10.1.
The IOMMU groups are indeed bad:

As you can see, the graphics cards are grouped together.
Alex, I've linked lspci -xxx -vvv and dmesg below. Please let me know if
you see anything, or need any more information.

I hope this is just a bug and that AMD isn't going the intel route
with making ACS a "server" feature.<br>
