Ah yes, the duplicate MADT issue is clearly a BIOS bug.
It is possible that we can tweak our Linux workaround for it to be more
Microsoft Windows Bug Compatbile(TM).

If interrupts fail using the open source nvidia driver, (and using the workaround
from the bug above to use the right MADT, please open a new bug report
as I think it would be an independent issue.
