Just dist-upgraded from 12.04 to 12.10 and I have started noticing it here too. Not only the 'chkhkhk' every 10 seconds, verified by iotop, but every now and then there is a high-pitched very soft whine as though it is spinning... i can stop this simply by running 'find /' and hitting ctrl-c. I have tried kernel 3.2 and 3.5, same result.
I shut down firefox - still happens. Used elinks for a while. Still happens.
The noise is unbearable. I am going to have to switch to a different distro or something.
