Hi, all:
	We are now porting ipipe on mips architecture. There is a
problem, after local_irq_enable() is called in start_kernel(), system
looks hung. We found that this may be related to printk in root domain,
if we use early_printk instead of printk, the system looks normal and
can continue the kernel boot process. Can someone tell me the possible
reason, thanks!
