I have this problem several times, always with the same harddrive, a samsung sp2004c. My samsung hd161hj and hd321kj don't seem to suffer from this problem. I do not know when exactly it happened for the first, but it has happened twice on a 2.6.22 kernel.
Is there anything that can be done about this (besides disabling adma for all drives), or any information i can provide to help? Please CC me, as i am not a member of this mailinglist.
