ml300 system init very slow

[VanBaren, Gerald (AGRE)]

Just in case nobody answered yet (I didn't see an answer), the problem 99.9999% certainty is that your serial interrupts are not interrupting so the kernel is polling for serial I/O.  This is a fallback operation with REALLY LONG timeouts.  The symptoms are REALLY SLOW console interaction == your symptoms.  Your follow-up message indicates the problem is in your serial driver module.
