Obvious question: is your stack set up properly, and is it big enough? It could be that you haven't set up a bigger kernel stack yet, and have overrun the small boot stack that the processor was running on. Do you know what the stack pointer is? If it is a few bytes below a page boundary, then overrunning the stack is a good guess.
