I'm just curious, how does the boot > wrapper run on a different arch than the kernel? The kernel can have a ppc32 boot wrapper for a ppc64 kernel. There's some rationale in the boot wrapper's Makefile: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/powerpc/boot/Makefile#n10 Cheers, Joel
