Just FYI, I tried this and the kernel booted: ./kexec -l -t elf-ppc64 --append='crashkernel=64M at 32M root=/dev/nfs rw ip=dhcp video=wuxga' /boot/vmlinux.strip I saw this output: kexec: waiting for cpu 1 (physical 1) to go down Reserving 64MB of memory at 32MB for crashkernel (System RAM: 128MB) ... Kernel command line: crashkernel=64M at 32M root=/dev/nfs rw ip=dhcp video=wuxga -Geoff
