Hi I installed the latest 4.6 generic AMD x64 kernel, and tested various
cd-r's and dvd-r's.  The problem is almost entirely fixed in the v4.6
kernel.  CD-R's mount automatically with the exception of certain x32
cd-r like the i686 bootable clonezilla image.  it does not mount, but it
will run if selected via BIOS at boot-up.  This behavior also occurs
with several other older windows disks (CD-R) as well.

Title:
  CD-R's not mounted in latest kernel

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  This bug affects both the X64 and X32 bit versions of the latest
  ubuntu 16.04 it does not occur with ubuntu 15.10 or earlier.  The
  problem is when a known good CD-R is placed in the drive, it is not
  mounted automatically.  However, if it is a bootable CD-R and you
  select the boot option of the BIOS it will function normally.

  Also, When a blank CD-R is inserted into the drive, it is mounted
  automatically, but disk creation software reports an erroneous amount
  of free space available.  Such as 247 MB or 512 MB when the disk is a
  700 MB disk.  However, if you proceed to record to the disk, even with
  an ISO image greater than the supposed available capacity, it records
  just fine.

  Other disk types such as DVD, audio, small cd-r work fine.  This only
  seems to affect the larger, full size cd-r's
