Since the error occurs at 2M, I am going to guess it is similar to
problem I had. The default link/load address for booting is 0x200000.
Here is a link:

This fix is for the arch/ppc tree. I don't know if the arch/powerpc tree
works the same way.
In the future, you should say what kernel version you are using and what
the error was.
