484 | It is an ongoing process to be certain the hardware in a machine | |
485 | is properly shutdown, so do not be surprised if this code does not | |
486 | initially work for you. It may help to enable device hotplugging | |
487 | support. As of this writing the exact hardware interface is | |
488 | strongly in flux, so no good recommendation can be made. | |
