To start with, I think you should fix the Machine Check
exception in head_8xx.S to get proper error reporting.
I think it should be:
	. = 0x200
MachineCheck:
 	EXCEPTION_PROLOG
 	mfspr	r4,DAR
 	stw	r4,_DAR(r11)
 	mfspr	r5,DSISR
 	stw	r5,_DSISR(r11)
 	addi	r3,r1,STACK_FRAME_OVERHEAD
 	EXC_XFER_EE(0x200, MachineCheckException)

Does init crash or just hang?
If it hangs, it may be a TLB problem.
