    ahci - Enforce 10-second poll of chipset
    * Enforce a poll every 10-seconds when the chipset is idle to try to
      catch any potential lost interrupts.  We have observed a number of
      'impossible' timeouts where the chipset registers indicate command
      completion, which should only be possible if a completion interrupt
      is lost.
