This could be a BIOS issue. Lots of posts on linux-kernel talking about
something like what you're each reporting. Here's the most useful
More recent ones:
I never noticed a cpu spike on my C610, nor a constant loading - that
might be a sign you're seeing something different. But if you have some
background job running periodically, it could be getting stalled by the
BIOS call, and that could cause your periodic cpu spike.
