Does /var/log/* have any clues?
No.

Hello,
I'm just curious: what is it in the kernel that wakes up about every
minute to do some work even on a completely idle machine? I'm asking
because xload shows some curious looking saw shaped load like this:
http://www.ccis.northeastern.edu/home/meunier/xload.jpg
That's on an idle Thinkpad T43 running OpenBSD 6.0-release. At first
I thought it might be something like cupsd, but even after killing
daemons one by one and going to single user mode these regular peaks
still continue. So I guess it's due to some kernel thread? I tried
to use "top -S" but couldn't figure out the source. Does anyone have
any idea of how to find it?
Thanks,
Philippe
Hi Philippe,
It is most likely the result of running X while idling measuring idling..
Well, it is most interesting what you would be trying to measure with it.
But Philippe is noticing this behavior even in single user mode, right?
In single user, init and a shell should be all that is running in userland.
If in single user, I would suspect hardware interrupting the kernel.
Make sure your monitoring tool isn't the culprit.
