Just FYI, I tried this and the kernel booted: ./kexec -l -t elf-ppc64 --append=3D'crashkernel=3D64M@32M root=3D/dev/nfs r= w ip=3Ddhcp video=3Dwuxga' /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) ...
