Okay... but it does not seem to be present at +16 sectors on the sd image provided by Fedora.

Honestly I would be surprised if it was since it exactly and incompatibly conflicts with the Cubieboard 2 uboot also required at +16 sectors of the sd image.

Sunxi guys need to do something better than that kind of build-time config hack.

Yes, I see the problem on my board with 3 different kernels, the original f21 alpha kernel, the updated kernel from f21 repo and the rawhide kernel.

I'm not sure it's equivalent to dt relationship to kernel, seems to be some nasty pre-uboot state that controls what the pre-uboot bootloader does (which uboot and kernel then rely on / inherit).

It's possible our different experience is related to your fex giving working onboard eth0 and my board (purchased from a subterranean otaku dungeon in Guanghua, Taipei where it may have rested a while first) has something that doesn't lead to a good result there.

I only updated the specifically the kernel with rawhide kernel by hand, by adding the rawhide repo disabled by default.  So it's not related to wrong default repos, the alpha is ok for that, and it hasn't drawn in anything from rawhide except parallel install of rawhide kernel*.
