that's the interesting part. What happens is that once init is running
and
things get a bit more formal, things start to slow down. There are lots
of
causes we've found for this, but interrupts is typically the big one.
The serial interrupt? Shouldn't it be easy like assigning it an irq? What other causes that you've found out? One possibility I can think of is the cache. It was turned off.

well, that was the other possibility I was going to mention, on our first tries at smp four years ago we'd see things run fast until the other SMP CPU got turned on, then run slow. Turns out the cache was only enabled on one cpu ...
