Yes, there is another way to get this issue unfortunately too. We moved
~ USB over Ethernet support on the Freerunner into a module. But, it's
commonly written around that folks should update their kernel by DFU.
This was never a good idea for a modular kernel (it does nothing to
update the modules) and now it's a really bad idea.
If you update your kernel by the packaging from inside the Freerunner it
won't make this problem as it updates the modules at the same time (now,
anyway, there were other problems with that method until recently).
If that's what's happened (try the Uboot update first though because
that fits the symptom as well) best plan is nuke these guys on your
device (kernel + matching rootfs) with dfu
and start over.
