have you installed multiboot? since it looks like you're using the default kernel maybe you're booting with the wrong one. If is this the case maybe you would like to install the kernel image of powerkernel, and then rerun the configuration of multiboot. This way you should at least boot in kernel power and get rid of errors in kernel-config show.
search the multiboot threads for the precise commands

ps: to see the multiboot menu you should reboot with the keyboard open.
