I don't see any reason not to move that resource into the northbridge to avoid that issue. It's a simple fix. Is there a good reason for having the MMCONF BAR in the APIC cluster?
This is what I was thinking. Build tested only.

Oh, this was very good! Thank you! Now I can load Linux kernel on the M4A78-EM, although it doesn't boot successfully yet.
I'm glad it's getting better. Your e820 doesn't look right, though.

Your devices have resources mapped from c0000000-e0000000 that don't show up. I can't remember where it would get that value from, but I think it is worth looking into.
Thanks, Myles
