Title:
  spurious completions during NCQ Hitachi
  HTS722016K9A300/HTS722012K9A300/HTS541616J9SA00/HTS542525K9SA00

Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux-source-2.6.22” package in Ubuntu:
  Won't Fix

Bug description:
  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
