Seen this when interrupts in irq.c were wrong based on The motherboard. In our case we'd use etherboot to Load the kernel (which doesn't handle interrupts) then Once kernel was loaded we'd see the problem. This Was fixed by fixing the irq table.

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 ...
