4.6.4 worked for me - it generates output and I need to build an initrd
for it to avoid the panic:

Here it is in action:

My kernel .config file for a minimal 1.8 MB bzImage is attached.

This is just weird. I can easily load a 3.18 kernel and boot it from flash.

4.6.4 with your config won't work at all.

Could you put your kernel somewhere I can try it out? I'm starting to worry
about my toolchain.

Also, do you use the bzimage or vmlinux? I would prefer to use the vmlinux
but have no idea if that would work.
