I have been able to confirm this on my System76 Darter. It appears to also have been the problem I've been seeing since feisty where the HD seems to always be in use. By deactivating APM (e.g. hdparm -B 255 /dev/sda ), my always in use issue has been resolved. My current Load Cycle is 333001 on a machine I bought in March. Also to note, that the load cycle increases also on AC Power, although not near as frequently as with laptop mode.
