I've tried, but no result... Please have a look at the snapshot of boot<br>
process.<br>
<br>
I think the kernel is not at all getting initiated to boot up.<br>
<br>
Whatever you see in the snapshot,<br>
1. "Modified cmdline:" is from<br>
"kexec-tools-1.101/kexec/arch/ppc64/fs2dt.c" putnode() function,<br>
2. "segment" lines are from<br>
"kexec-tools-1.101/kexec/arch/ppc64/kexec-elf-ppc64.c" elf_ppc64_load()<br>
function.<br>
<br>
KEXEC is used by KBOOT to boot the (secondary) linux kernel. But I am<br>
wondering why the kernel is not booting up when I give "crashkernel"<br>
option.<br>
<br>

I use kboot latest version (kboot-20080201).<br>
Please refer to<br>

0080201-ADDON/src/</a> for src of kboot.<br>
