var/log/messages repeated message question.

5 May 2004

      I'm seeing this sort of thing in my system log:

May  5 16:59:00 linux /USR/SBIN/CRON[18323]: (root) CMD ( rm -f /var/spool/
cron/lastrun/cron.hourly) 
May  5 16:59:02 linux kernel: Device not ready.  Make sure there is a disc in 
the drive.

May  5 17:09:49 linux last message repeated 24 times
May  5 17:10:50 linux last message repeated 24 times

..... and on and on...

How should I proceed?
Is the 'device' my CDROM?
