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: <http://patchwork.ozlabs.org/linuxppc-embedded/patch?id=14717> 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.
