Weird.

Can you try:

  d690740f22f6 ("powerpc/powernv: Enable LEDS support")

That is the commit before my merge of Scott's tree, which had all the Freescale
& 32-bit stuff.

If that works, it would isolate it to only about 30 commits from Scott's tree.

My theory is it is not a kernel problem at all; instead, uboot overwrites
some little part of the kernel image.

u-boot is just loading a cuImage which is a kernel with appended
device tree. So u-boot is out of the picture, still investigating
(when time allows)
