So after patching my kernel with ACS and the Agesa patches and using downstream, multifunction setting for the ACS the Designare EX is finally usable for me. I still got some trouble with the reset of the NVMe drive (stubbed via vfio) i pass through to windows (Samsung) when the VM is shut down but thats just annoying and no showstopper. For network i don't pass through the NICs but use an USB network adapter for windows which is just fine. The not so important (latency wise) VMs are bridged to the hosts NIC. For sound i use a Corsair wireless headset with usb dongle which can be passed to the windows VM and gets recognized (back) by the host flawlessly when shutting down the windows vm. So in overall id call it a success story for the Designare EX. Im just a little disappointed about the need for ACS, as this wasn't necessary on my former ASRock X370 Killer SLI AM4 board.

To me it looks more Bios or Hardware-related so i hope to get some answer from users of the same hardware and Bios. However i totally understand that i will not get any help by Unraid staff when not using their software.

Sorry, i am not using unraid. Im using Fedora 31 with ACS patch. Hope thats fine in this forum. Does the distro flavor have any influence to the IOMMU grouping?

First of all, thank you for sharing the information above. I've running F12i Bios with the same board and my non boot NVME drives arent in any IOMMU Groups at all. (im using all 3 M.2 slots) They show up with lspci but not using the script here: https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF#Ensuring_that_the_groups_are_valid When i try to start my VM i get "Fehler: Interner Fehler: Process exited prior to exec: libvirt: Fehler : Interner Fehler: Ungültige Einheit 0000:42:00.0 iommu_group Datei /sys/bus/pci/devices/0000:42:00.0/iommu_group ist kein symlink" (sorry my system is localized to german) Have you encountered such situation too?
