I've tried, but no result... Please have a look at the snapshot of boot

I think the kernel is not at all getting initiated to boot up.

Whatever you see in the snapshot,
1. "Modified cmdline:" is from
"kexec-tools-1.101/kexec/arch/ppc64/fs2dt.c" putnode() function,
2. "segment" lines are from
"kexec-tools-1.101/kexec/arch/ppc64/kexec-elf-ppc64.c" elf_ppc64_load()

KEXEC is used by KBOOT to boot the (secondary) linux kernel. But I am
wondering why the kernel is not booting up when I give "crashkernel"

I use kboot latest version (kboot-20080201).
Please refer to
src of kboot.
