--- Comment #44 from Christian Hartmann <cornogle at googlemail.com> ---
I have tested with latest 4.3.0-rc1 from torvalds with the SeqV3 patches
applied too.

So far not fixed yet.
What I also noticed a while is the message seen below the ioremap errors

</snip>

It is also a new feature since kernel release 4.2 AFAIK.
But like with the BGRT from the ACPI tables, there seems to be something else
wrong. Do not really know yet, if this is the core of this issue here...
