Depending on your rootfs (ie, Debian) it can be doing fsck on your ext3
filesystem during initscripts there and seem pretty hung -- you'd be
able to see it with debug board.

What's planned for partition selection is you will in future be able to
press AUX while Qi is pulling in the kernel it selected to abort the
load and move to next usable partition, so I think multiboot will work
out fine if you can remember which "n'th" rootfs it is you want...
hopefully only a problem for people with >2.

It's a nice idea to leverage NOR but I think Qi will take care of it
soon and allow more that one alternative rootfs.
