I've tried, but no result... Please have a look at the snapshot of boot process. 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() function. 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" option. > > How do you boot the kernel, by yaboot or kboot? I use kboot latest version (kboot-20080201).
