Well after a bit investigating it seems that it has something to do with "cpudyn". After i shut down cpudynd the errors didn't occur anymore.

Is this now a cpudyn or kernel error and does somebody know how to fix it beside not using cpudyn?

bye,
Johannes

Welcome to the forum!

Just to let the developers know, it'd be great if you filed a bug with a full dmesg output on the bug tracker, http://bugs.archlinux.org/ along with the package version involved. Some of us read the forums, but to guarantee a response, the bug tracker is the best place to go.
