Well, you have some different problem then. I was assuming you used
-funit-at-a-time because you posted on the unit-at-a-time thread.
I don't know what's wrong with your kernel, sorry.

If it happened to me here I would add printks to the early kernel 
initialisation until I figured out where it hangs.
(it's somewhere after mem_init and before console_init in 
init/main.c:start_kernel). You could try that, together with earlyprintk.
