Title:
  setting drive speed: bad/missing CDROM/DVD-speed value (0..255)

Status in “hdparm” package in Ubuntu:
  Confirmed

Bug description:
  My DVD drive is disturbingly noisy. Setting its speed to 4x is
  sufficient to watch movies, yet quiet.

  With 3.2.0.41.49 it worked as expected.
  With 3.2.0.43.51 (after upgrade) results are as follows:

    [just as with old kernel]
    root at computer:~# hdparm -E4 /dev/sr0
    /dev/sr0:
    setting cd/dvd speed to 4
   [but now the drive is not slowing down; querying drive speed to check back yields the following: ]
    root at computer:~# hdparm -E /dev/sr0
      -E: bad/missing CDROM/DVD-speed value (0..255)

  dmesg doesn't report anything on the issue.

  I have unattended-updates running and according to the logs,
  3.2.0.41.49 has been the last automatically installed version. I had
  to jolt upgrade to 3.2.0.43.51 by hand (apt-get install linux-generic
  linux-image linux-foo).

  The bug is similiar to
  https://bugs.launchpad.net/ubuntu/+source/hdparm/+bug/538351 in regard
  to what does not work, but different in symptoms on screen (and the
  other bug is three years old, different kernel and hdparm version
  today).
