Regarding the "ACPI-0438: *** Error" message -- no idea.  That
looks like, possibly, some bad ACPI configuration data.

Regarding the "can't get _ADR" messages: I have Asus AMD-based
boards, Gigabyte Intel-based boards, Tyan boards, Supermicro
boards, and true Intel boards all which do this.  What it means
and why it's printed, I don't know -- thus I've concluded,
generally speaking, it's a harmless kernel message.
