@chicagomed said in Passthrough Contention Problems with Console and Linux VM: @TeddyAstie great will take a look this weekend. Is there anything in particular you want us to test / check out? What works/doesn't work and overall performance.

Ok just to close the loop here. Problem persisted with Intel Arc (the only thing I forgot to do was disable REBAR, but I don't think this is a related issue). Upon installing Radeon RX 6400, pass through worked without any issue. Of note, on the Arc I got two separately numbered PCI devices 0000:0b and 0000:0a where as with the AMD it was 0000.08.01 and .02. I'm not sure if that helps hint at the issue --something to do with grouping and not grouping? This is way above my head but I noticed the difference. I'm still having issues with pass through into Linux but that is a separate topic. Looks like we have a good discussion of this issue on the other post and so I will stay on that one going forward. Thank you!
