I came on Monday from four week leave and have been basically been
catching up with my emails :-) I'll look into this next week with
time.

The error message is saying that someone else has reserved the resource
(-EBUSY).

This looks odd:

e78bf000-e7bbefff : ACPI Non-volatile Storage
  e7bb6000-e7bb9fff : MSFT0101:00
  e7bba000-e7bbdfff : MSFT0101:00

Why would be TPM registers mapped inside ACPI NV?

I would *guess* that what is happening is that perhaps drivers/acpi/nvs.c
maps the address space. This looks like a firmware bug, and such that we
cannot do anything about it.

I'm having a weird issue with the ACPI tables:

This has not happened to me before.
