Just so that we are on the same page: I've backported Nikolaus's patch for upstream here https://github.com/acpica/acpica/pull/506 and Bob has implemented the new API here: https://github.com/acpica/acpica/commit/c69369cd9cf0134e1aac516e97d612947daa8dc2 Once we do a release, I will send Bob's change to the linux ACPI mailing list. Feel free to use this new API where you see fit. Thanks, Erik > > Thanks, > Rafael
