    acpi - Implement a hack to recheck whether devices are present a few times.
    
    * This allows various ACPI devices to attach, which depend on another
      device. Often the _STA method declares them absent when the initial ACPI
      namespace walk is done, so we re-check the presence of those devices
      after each global priority round, when probe-/attach-ing children.
