[CentOS] Boat loads of: 'localhost kernel: cdrom: open failed.'

Another question: 
How can a supress these messages from filling up my syslog file?

Mar  1 01:31:26 localhost kernel: cdrom: open failed.
Mar  1 01:31:57 localhost last message repeated 15 times
Mar  1 01:31:59 localhost kernel: cdrom: open failed.
Mar  1 01:32:01 localhost kernel: cdrom: open failed.
                                                           
I've got 'noauto' in /etc/fstab.
I've also shut down 'autofs'

So far the only way I can stop them is to put a cd in the drive. 
I'd prefer not not have any kind of auto mount system running if that helps. 

Thanks again.

My fstab entries:
