    AHCI - DHRS interrupt does not stop command processing.
    Not only does the DHRS interrupt not stop command processing (which means
    that ahci_pm_read() needs to be single-threaded by the way, which we only do
    by happenstance atm), but we were stopping and starting the port without
    reloading commands in-progress.
