ACPI Errors
Hello,
I've been having the following error messages about 'ACPI' in my 'kern.log' and haven't been able to figure out how to resolve them. The system boots successfully after displaying the errors, but any error message is usually a concern of mine.
Is this something I should be worried about? Is there any way I can eliminate these errors?
Regards,
Jonathan
