ACPI error message

[Davide Petilli]

During the boot I can see these error mesages related to acpi.
I've built my kernel but the error messages come up on the default kernel too. 
Does anyone know what is it and how to solve this?
I tried to figure it out by myself without succes.

These are the relevant parts of my dmesg:
