OK! I have found a fix for this problem!!! (actually found the fix in one of the fedora forums)
Let me first clearly define the problem that I am fixing: Conditions: 1. CD/DVD/CDR/CDRW disks "unmount" themselves shortly after mounting. 2. dmesg reports the following - VFS: busy inodes on changed media or resized disk sr0 3. I currently have no entries for either drive in /etc/fstab... The problem was exactly the same when I had the "/dev/sr0 /media/cdrom0 udf,iso9660 noauto,users 0 0" or similar lines in /etc/fstab. 4. Once one of the drives "unmounted", only a reboot would allow me to mount again. 5. All other devices and drives mount normally (and stay mounted with no issues).. 6. My relevant hardware is: Asus P5N-e motherboard, cdrom:0 :: description: DVD-RAM writer :: product: CD/DVDW SH-S182D cdrom:1 :: description: DVD-RAM writer :: product: CD/DVDW SH-S182D Both drives are run off the secondary ide channel. 7. The hardware (motherboard and drives) is guranteed to be functional. I could not get either drive to fail in WindowsXP during overnight testing. FIX:: Add "acpi=off" to the kernel load line in /boot/grub/grub.cfg then reboot... For example: linux /boot/vmlinuz-2.6.32-24-generic root=UUID=c82dfc28-0bcf-48a6-995f-b61464bcf056 ro quiet splash acpi=off I have gone through 2 days of stress testing the drives and neither has unmounted AND there are no more errors in dmesg... TO DO: 1. Get more users to confirm this fix. 2. Submit the data to the ACPI team if it looks like the fix is repeatable.
