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

  731. but it is indepedent of the system firmware. And like a reboot
  732. you can start any kernel with it, not just Linux.
  733. The name comes from the similiarity to the exec system call.

  735. is properly shutdown, so do not be surprised if this code does not
  736. initially work for you. It may help to enable device hotplugging

  1729. and more information, read <file:Documentation/pm.txt> and the
  1730. Battery Powered Linux mini-HOWTO, available from
