Title:
  blkid spends long time scanning Audio CD

Status in “udev” package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: udev

  $ lsb_release -rd
  Description:	Ubuntu 10.04 LTS
  Release:	10.04
  $ apt-cache policy udev
  udev:
    Installed: 151-12
    Candidate: 151-12
    Version table:
   *** 151-12 0
          500 http://gb.archive.ubuntu.com/ubuntu/ lucid/main Packages
          100 /var/lib/dpkg/status

  Expected:
  Audio CD to be inserted and to load a audio player.

  Happened:
  Audio CD inserted and drive spent a long time (30 secs-1min) scanning the CD (very loudly).

  Potential fix:

  Although similar to #490925 the problem seems to stem from the rule in
  60-persistent-storage.rules which has:

  # probe filesystem metadata of optical drives which have a media inserted
  KERNEL=="sr*", ENV{ID_CDROM_MEDIA}=="?*", ENV{ID_CDROM_MEDIA_SESSION_LAST_OFFSET}=="?*", IMPORT{program}="/sbin/blkid -o udev -p -u noraid -O $env{ID_CDROM_MEDIA_SESSION_LAST_OFFSET} $tempnode"

  # single-session CDs do not have ID_CDROM_MEDIA_SESSION_LAST_OFFSET
  KERNEL=="sr*", ENV{ID_CDROM_MEDIA}=="?*", ENV{ID_CDROM_MEDIA_SESSION_LAST_OFFSET}=="", , IMPORT{program}="/sbin/blkid -o udev -p -u noraid $tempnode"

  I added ENV{ID_CDROM_MEDIA_TRACK_COUNT_DATA}=="?*" to the list of
  checks and it seems to make blkid behave itself.  I dont know how many
  CDs have a mix of data and audio but hopefully this modification will
  work for now.
