the failure of UUID, \_SB_:_OSC invalid UUID is due to the firmware checking another different UUID(ED855E0C-6C90 -47BF-47A6-2A26DE0FC5AD5C) by method OSCM and WOSC and return invalid UUID before the actual Platform-Wide UUID (0811B06E- 4A27-44F9-8D60-3CBBC22E7B48) defined in the APCI spec and we expected to be checked,
