I think the important piece here - and the reason I filed the issue
against edk2 - is the following from the Description:
"Neither issue is reproducible when booting in non-UEFI mode."
Since I can passthrough devices just fine in legacy BIOS mode, I
assume all of my host BIOS/host kernel configuration is OK.
