Fabian,
That's what I have when booting with the generated uImage-3.10.80, while it boots fine with the uImage (coming from ubuntu, so something we'll never ship, as we'll only build images with packages built on the centos infra, and reproduceable, like I've done for the raspberrypi2 kernels, built through mock in rpm format)
I'll keep this in mind.
Manuel,
I will gladly test on my U3 if an image is made available
The XU3 requires a completely different kernel according to this http://odroid.com/dokuwiki/doku.php?id=en:xu3_building_kernel XU3 requires the branch odroidxu3-3.10.y and the C1 requires the branch odroidc-3.10.y
