Browse source 
The following error is observed in Linux:
[   30.255680] ACPI Error: Aborting method \_SB.FUR4.AOAC._OFF due to previous error (AE_AML_LOOP_TIMEOUT)
It caused a boot delay issue in the virtualization case above due to
some mmio regions not being passed through and the acpi interpreter
waiting.

reserve MMIO regions which are used by ACPI code in order to fix this
issue.
