The initramfs image is correct.

It seems to be an endianness issue, in that it's never show up on any of the little endian configurations. If your board is endianness selectable, I'd suggest trying little endian and seeing if that works. Little endian certainly gets the bulk of the testing, so it's quite possible that there are some things broken on big endian.
