Yes that what I suspect too but so far I can't figure out which ACPI
part could be missing. According to my probe, after the page
translation, the guilty address seems to point to valid memory area
(DDR).

When I said I followed ACPI tips I mean I refered to kontron/986lcd-m,
the coreboot acpi page, and also some tricks disccussed on the mailing
list (64-bits alignment, fadt correct size according to version...).

I was hoping someone already met this issue and could give me a clue.
