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

  725. but it is indepedent of the system firmware. And like a reboot
  726. you can start any kernel with it, not just Linux.
  727. The name comes from the similiarity to the exec system call.
  728. It is an ongoing process to be certain the hardware in a machine
  729. is properly shutdown, so do not be surprised if this code does not
  730. initially work for you. It may help to enable device hotplugging

  732. strongly in flux, so no good recommendation can be made.

  1723. and more information, read <file:Documentation/pm.txt> and the
  1724. Battery Powered Linux mini-HOWTO, available from

  1731. random kernel OOPSes or reboots that don't seem to be related to
