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.

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 ...
