Problem Description: 

Mounting cdrom on sun4 machines gives erroneous error message 
in following situation:

- mount /dev/sr0 when there is no cd in the drive 
  (correct error message is displayed)

- load the cd in the drive and mount /dev/sr0.  cdrom mounts correctly
  but with the following error message on console:

sr0a:  start/stop unit(LoEj) retry
       sense key(0x2): not ready,  error code(0x20): invalid command

This is just a warning message and won't hurt to be disabled.
