Problem description:
====================
Getting error messages in /var/log/messages relating to the IDE cdrom
device whenever I eject/load a CD (music/audio or data - doesn't matter
which one). Messages in question are:

The messages only appear in the log file when the CD is ejected from or
loaded into the CD-ROM drive, not when the audio tracks are played or
when the data CD is mounted/unmounted.
Never had this problem with 2.2.15, only with 2.2.16.
Linux System information:
=========================
Debian GNU/Linux 2.3 (woody)
Kernel Version:
===============
@phoenix:[/home/ssahmed] cat /proc/version
Linux version 2.2.16 (root@phoenix) (gcc version 2.95.2 20000313 (Debian GNU/Linux)) #1 Thu Jun 8 20:44:12 EDT 2000
Kernel Patches:
===============
I have patched the kernel with the lm-sensors2 sources.
Hardware:
=========
Intel Celeron 300A overclocked to 450Mhz
128 MB 100MHz RAM
Quantum 10.2 Gb UDMA HD
Creative Labs 52x IDE CD-ROM drive (connected as master on the second
IDE channel/port)
Matrox Millennium G200 8MB Video card
Creative Labs PCI128 sound card
Workaround/Fix:
===============
Switch back to kernel-2.2.15. That lets me play my music/audio CDs
without getting any messages of the above type.
Environment:
============
