Hi,
Looks like it fails to boot on a p9 qemu/kvm guest even out of grub: hangs trying to bring up SMP. That's probably what we saw in bare-metal too, the console probably just didn't catch up.
I will continue investigating, but I'm not sure what kernel tree you're using: git://git.
Kind regards,
Daniel
