Boot from usb partition with name rootfs (1 reply)

I have a wheezy installation on an external hdd which I want to use on a pink pogoplug. I labeled the rootpartition rootfs, and now would like to boot from this partition even if the other usb hdd are attached. I don't think they contain bootable structures / files.

I followed

but I get the following:

and there it stops (or do I have to wait a few minutes?).

In contrast, when I switch off the power of the other external hdd (usb connected, power not), I get

Is there any way to tell uBoot to boot from rootfs? I already changed the fstab to use LABEL=rootfs for / but I assume that comes in later?
