Now we have no idea how the behaviour is changed with the boot option.
In fact the boot option is useful for all the boxes that can't be
resumed unless it is added. 

Although the machine is modern, the ACPI 1.0 is followed on this box.
Without the boot option of "acpi_sleep=old_ordering", it can't be
resumed from S3 correctly. But after adding the boot option, the box can
be resumed.
