I think I have found the solution (read it somewhere but forgot where). My laptop seems to have a Hitachi and it doesn't do complete NCQ. Some of their drives seem to be blacklisted, but I guess mine isn't (HTS541010G9AT00).
To solve the problem add this line to your /etc/rc.local sh -c "echo 1 > /sys/block/sda/device/queue_depth" This will disable NCQ.
