Sorry I do not keep any logs, I'll do next time.

We got this running in a board of ours, it is provided by a script in
the initrd, it loads a kernel from NOR then chain loads into kernel
provided by rootfs. I guess that would be a separated bug report.

Yet another comment, when installing a cross compiled kernel it does
not contain an initramfs, so it would be nice if the hook in
flash-kernel takes care of it too.
