Comment 33 for bug 1188647

This is not the right bug report, and we need to get off it before others start to complain.
However, it isn't time to open a new one yet, in my opinion, because we don't yet know what to file it against.

Well, a lot of people do just that, but then also wonder why issues don't get solved. Issues don't get solved if people don't investigate.

Myself, and without any proof, I suspect thermald is your root issue. Have a look at this bug: https://bugs.launchpad.net/ubuntu/+source/thermald/+bug/1656528

By the way, a cool trick for some of the stuff you were listing above is to do this instead:
