Symptoms:

	( SR:8606213570 CR:JAGad82762 )
	The system hangs during boot.

Defect Description:
	PHKL_25011:
	( SR:8606213570 CR:JAGad82762 )
	The ACPI code was using the wrong data structure to read the
	global locking rule.  This caused the machine to hang during
	boot as the ACPI code was incorrectly waiting for locks on
	resources that were actually free.

	Resolution:
	The ACPI code was changed to use the correct data structure.
