I get the same problem.
I just received a SSD Disk, so I did a fresh install of Natty Alpha 3 and get the error since the first boot (2.6.38-5)
Update to be up 2 date change nothing (2.6.38-7 essentially)
I didn't remember getting this issue with my old disk before (I was already in Natty since it was avalaible by updating from 10.10)
