  1599. kexec is a system call that implements the ability to shutdown your
  1600. current kernel, and to start another kernel. It is like a reboot
  1601. but it is independent of the system firmware. And like a reboot
  1602. you can start any kernel with it, not just Linux.
  1603. The name comes from the similarity to the exec system call.
  1604. It is an ongoing process to be certain the hardware in a machine
  1605. is properly shutdown, so do not be surprised if this code does not
  1606. initially work for you. It may help to enable device hotplugging
