Title:
  /dev/dvd1 etc. disappeared OR: Two optical drives with same name?

Status in “udev” package in Ubuntu:
  New

Bug description:
  Hi
  I have 2 Optiarc DVD Drives (DVD RW AD-7280S) connected to a SiI 3114 controller. At boot they both show op.  When running Mint (Nadia), I can access them as /dev/sr0 and /dev/sr1 respectively.
  But the second drive has no symlinks
  cd /dev
  ll | grep 'sr[01]'
  yields only
  cdrom -> sr0	cdrw -> sr0	dvd -> sr0 and	dvdrw -> sr0
  sr0	sr1

  cd disk/by-id/
  ll | grep 'sr[01]'
  yields
  ata-Optiarc_DVD_RW_AD-7280S -> ../../sr0

  cd disk/by-path/
  ll | grep 'sr[01]'
  yields
  pci-0000:05:00.0-scsi-0:0:0:0 -> ../../sr0

  When I connect one DVD drive to a different SATA controller, this changes to (nearly) what one expects.
  cd /dev
  ll | grep 'sr[01]'
  yields
  cdrom -> sr0	cdrw -> sr0	dvd -> sr0   and	dvdrw -> sr0
  cdrom1 -> sr1	cdrw1 -> sr1	dvd1 -> sr1 and	dvdrw1 -> sr1
  sr0	sr1

  cd disk/by-id/
  ll | grep 'sr[01]'
  still yields only
  ata-Optiarc_DVD_RW_AD-7280S -> ../../sr0

  cd disk/by-path/
  ll | grep 'sr[01]'
  yields
  pci-0000:05:00.0-scsi-0:0:0:0 -> ../../sr0
  pci-0000:04:05.0-scsi-0:0:0:0 -> ../../sr1

  Obviously the 2 DVD drives interfere with each other, when on the same controller.
  Is this caused by 
  1.  ata-Optiarc_DVD_RW_AD-7280S not having something unique (a serialnr) in its name? Like in SAMSUNG_HD103SJS246JD1B2050
  a. would this mean a bug in the (udev?) naming scheme?
  2.  or is the  SiI 3114 controller the culprit?

  I'm running Mint on top of Ubuntu quantal
