kexec

[leo kirotawa]

Sorry, silly question, but did you try as root? kexec load tries to put the
knew kernel on memory and after that tries a syscall to kexec_load to
finish with a kexec_reboot, since it handles with mem and syscalls maybe
just as a root you will run it properly

 Also have that kexec at lists.infradead.org list.
