So you have applied 173c7803592065d27bf2e60d50e08e197a0efa83 and it
causes a regression for you?

As I understand it, before applying 173c780359206 you where capable of
booting the PVH Dom0, albeit with non-working USB?

And after applying 173c780359206 you are no longer able to boot?

At least part of the issue seems to be that the IO-APIC information
provided to Dom0 is wrong (from the attached log):

Can you try to boot with just the staging branch (current commit is
008a8fb249b9d433) and see how that goes?

Thanks, Roger.
