Comme= nt # 22 on bug 10852= 1 from Robert Strube 
OK! My hunch about the PM was right! The card is fully initial=
ized now, so the
issue doesn't appear to be a PCI resource issue!

I took the brute force approach, compiled my own custom kernel that complet=
ely
disabled the Vega M (by commenting out it's device IDs). I then passed in t=
he
following kernel boot parameters:

acpi=3Doff apm=3Doff amdgpu.dpm=3D0 amdgpu.aspm=3D0 amdgpu.runpm=3D0 amdgpu=
.bapm=3D0

Rebooted the machine and *BAM* the eGPU was initialized!

I'm attaching the new dmesg!

I'm just super excited that I was able to get the eGPU initialized!

xrandr even sees it!
