I believe  this has been triggered because you've enabled initrd in the 
kernel, but the MicroBlaze arch is lacking the free_initrd_mem() support 
function.

Can you please apply with attached patch (with "patch -p0" from 
linux-2.4.x directory), and see if it resolves the issue?

If so, I'll commit it to CVS.

Thanks,

John
