According tou your log, your kernel image file was found and loaded successifully, so what fails is one of the steps after that. I am fairly sure you are missing your harmattan preinit file, as that is the most common failure after a misplaced kernel image. To make sure, please check that you have /sbin/preinit_harmattan on your root partition. If you are missing it, you can copy your existing preinit file and it should be OK. To do that, enter the collowing command as root: "cp /sbin/preinit /sbin/preinit_harmattan" After that, just reflash your ubiboot kernel and you should be fine.
