  229. kexec is a system call that implements the ability to shutdown your

  231. but it is independent of the system firmware. And like a reboot
  232. you can start any kernel with it, not just Linux.
  233. The name comes from the similarity to the exec system call.
  234. It is an ongoing process to be certain the hardware in a machine
  235. is properly shutdown, so do not be surprised if this code does not
  236. initially work for you. It may help to enable device hotplugging
