The wait_init_idle loop is there to protect you from a race condition
between reschedule_idle and init_idle (the boot CPU can call reschedule_idle
before all secondaries have called init_idle, which is bad). You might want 
to take a look at whether the MQ scheduler patch affects this area of the
boot sequence. I'm assuming virgin 2.4.13 boots fine for you?
