Wohoo, you're great, that was it:

root     29547  0.0  0.3   7516   996 ?        D    Nov25   0:00 CROND
root     29548  0.0  0.3   7516   996 ?        Ss   Nov25   0:00 CROND

I stopped it, and loadavg is back to 0.

Now I have to figure out what CROND was doing...

Does ps always show processes in D state in CAPITAL letters?

After cron restart it is "crond", as usual.
