Are you running lmsensors?

If so, remove it and any modules it loads.

It took me a year of intermittent freezes to figure out that that was the
problem on one of my machines.

I have used a KVM switch for years; I've never known it cause a freeze. (I
have, though, occasionally fingered it as responsible for getting a system
into such a confused state that I've ended up rebooting; I've learned now
not to switch amongst my machines [I have four on the switch] when I'm
booting or closing down one of them.)
