Public bug reported:
Binary package hint: linux-source-2.6.22
I get lots of spurious completions during NCQ on linux-
image-2.6.22-10-generic, 2.6.22-10.30 with the following Hitachi
harddrive. I read that this was fixed and released in another bug, but
obviously it's not for this drive.
hdparm -I /dev/sda
ATA device, with non-removable media
Model Number: Hitachi HTS722016K9A300
