Hmmm, I have easily around 500-600 wakeups/second. But I do not even see plasma-desktop in the process list on the Overview tab of powertop. No, no plasma-desktop there at all. But stuff like KWin, Dolphin, Kmail, Akregator, some Konquerors which were preloaded - why are these doing anything anyway? -, sometimes Iceweasel, and various Nepomuk stuff like nepomukindexer, nepomukservicestubs and virtuoso-t, as well as postgres for Akonadi, some interrupt threads (I use threadirqs kernel option) and BTRFS. Still fan isn´t even running most of the time. Sandybrdige CPU is in C7 sleep state in 87% of the time. It idles in about 30-35% of the time and is at 800 MHz in about 60% of the time. Rest is distributed among frequencies with the bulk of 2-8% in turbo mode. The machine is basically doing nothing except for those wakeups. Thus is you have plasma-desktop in the first place, I think this is not normal. Unless you do not run anything else at all in the moment. I think I will try with all user applications closed and look again. I would test with a new user with a bog standard KDE configuration first. If that is better I would disable plasmoids one by one starting with those which I added yourself until I find the culprit. Since these are running in the context of plasma-desktop and I am not even sure whether they run as threads there, I do not know any other approach that would work.
