We do have the right kernel support for our didsks. But, you do not need a lot of CPU activity to generate noise. Just enough to disrupt the cashe. Does kupdated run every 5 minutes? If so it could still be the culprit.

So, my question is does anyone know of a kernel thread or daemon in the 2.4 kernel that wakes up every 5 minutes?
[kupdated] can cause massive CPU load if your kernel does not have the IDE chipset support for your system. I think it flushed any data in the HD
buffers to disk and if the chipset support isn't there, then the main CPU has
to do this using PIO.
