| | 965 | kexec is a system call that implements the ability to shutdown your |
| | 966 | current kernel, and to start another kernel. It is like a reboot |
| | 967 | but it is independent of the system firmware. And like a reboot |
| | 968 | you can start any kernel with it, not just Linux. |
| | 969 | |
| | 970 | It is an ongoing process to be certain the hardware in a machine |
| | 971 | is properly shutdown, so do not be surprised if this code does not |
| | 972 | initially work for you. It may help to enable device hotplugging |
| | 973 | support. |
