Sorry, should have said "output in kernel log". Must have been confused.
OK, I found this in kern.log:
Booting with the older version 0902:
---------

Series/Z97-A, BIOS 0902 05/08/2014

No problem, proceeds to load next module.
Then booting with BIOS 1008 (and same for later ones)
---------

So there is a conflict.

That's what I thought. That might be an oversight by ASUS, or the BIOS is
now genuinely accessing the chip. You can boot with acpi_enforce_resources=lax,
on your own risk. You could also try to decode the DSDT to find out what
the BIOS is doing, but that is not easy.
Problem is that ASUS doesn't support Linux on their PC boards, so they won't
help you much.
