My system definitely has a problem with load (and not only with a display/calculation of the load value that is wrong).
Every task I do on the system takes ages. For example, "apt-get upgrade" for linux-* 3.2.0-24.38 took ~35 minutes. In general, disk access seems to be very slow, and if there are multiple processes running (backup, mlocate.updatedb, or other simple but disk IO bound tasks) the system load is easily around 8-10. Like Rafael, I am using an encrypted LVM setup. Maybe the calculation of the load values is not related after all?
