This has nothing to do with the kernel. I guess, it's a cron job. Do a

$ grep find /etc/crontab /etc/cron*/*

and look wether one of the entries corresponds with the time when your
machine becomes unusable.

Please - can someone explain what happens here once a day when my machine 
becomes completely unusable, a tremendous amount of disk i/o begins to occur, 
and 'top' shows "run-parts" and "find" at > 80% cpu utilization. What are 
they doing?  Are they necessary?  Can they be controlled. In Googling for 
these answers first, all I see are compaints, but no answers. Can someone 
PLEASE either explain what these are doing and how they are controlled, or 
point me in the right direction? Many thanks.

    Your problem has nothing to do with the kernel itself. Your
problem is that you have cron jobs that eat resources. If you don't
want them, just disable cron, or delete the cron jobs, etc...

    Without knowing your distro, your cron config or more details for
you system I cannot tell you more. Just in case, find is a binary
for... finding files; run-parts is for running things in your
/etc/rc* directories and kupdated is the buffer cache manager (well,
more or less...). BTW, googling for 'kupdated' shows a lot of info...

    I don't know of a mailing list related to this kind of questions,
so I think this can be as good as any. If you want more help you will
have to give me more information about your problem.

Look for updatedb in your cron jobs. That's usually what causes a bunch of 
find activity for me. You can either diable them or setup /etc/updatedb.conf 
to prune some fs's/path's that don't need to be slocate'd. HTH
