I see. Could you try 8.3 or 8-stable and see if that boots. I've
most of the USB changes to 8-stable. If 8.3 boots, I believe it is not
problem, but ACPI or PCI most likely or something else.
just downloading 8.3RC1 now, and will burn and attempt install
8.3RC1 boots all the way to the first install screen. So it appears
to NOT have the problem which 9.0 has.
