May 15, 20215 yr No idea wtf is going on. My iommu group keeps changing even though nothing has changed. Is this an unraid bug or could it be my motherboard?

[AMD] Starship/Matisse HD Audio Controller My GPU used to be 07:00.1 (This is what it is when i first got this motherboard) then at random times it will change to 09:00.1 then back to 07:00.1. Last week it was 07:00.1 and 2 days ago it changed to 09:00.1 and today it changed to 0a:00.1. My USB controller changed as well. Anyone ever experienced this before? Really annoying!

May 16, 20215 yr X370 ( Asus ) B450 ( Asrock Gigabyte ) X399 ( Gigabyte ) I have a bug report case happen in X399 about IOMMU, pls try setting IOMMU from AUTO to Enable in BIOS and check does this could help. Edited May 16, 20215 yr by Vr2Io
June 20, 20215 yr Author It happened again!!!!! Nothing changed in bios. No hardware changes. Just turned computer on and bam! Iommu group changed!!!
