Red Hat Bugzilla – Bug 18676
Autorun, Auto mount or Cd_ROM errors!!!
Last modified: 2005-10-31 17:00:50 EST
I have two systems the one I recently upgraded from rh6.2 to rh7 and know
I can't read some CD-ROMs on the system. This was not the case with rh6.2
or rh6.1 I take it that this is a bug with your new enhancement that you
don't have to unmount the CDROM to remove it (which by the way is a pretty
And what makes me sure it is a bug is the fact that I made a fresh
installation on my other system a IBM 300PL and I have the same problems.
The errors include:
Not showing al the files on the CD-ROM.
Not displaying the names of the files or directories on the CD-ROM.
Not being able to mount the CD-ROM error bad supperblok.
What is strange is that on my first system I have a HP9300 CD writer on
the secondary IDE as master and a LG 48X8 DVD_ROM on the same IDE Channel
as slave, and I only have this problem on the HP9300.
PS. I was using a GNOME desktop so it could be that but I doubt it.
Just a suggestion, unlikely to be a fix:
The autofs mounts have timeouts associated with them,
and it affects howlong the system takes to unmount a
device (like the cdrom). Only after it has unmounted the
old one, will it mount a new one (even if it has been swaped)
You can look at this in the /etc/auto.mnt file, but I'm not sure if it is
The cds in question might use the joliette extension, and I'll have to ask the
kernel guys if the kernel shiped with 7 reads that. Or, the cds might be
getting marginal, and one drive is better at reading them.
Can you find any pattern in the CD-ROMs that it wont read?

I have some of the same CD-problems with my RH-7.0 systems, and would like to
add a comment.
I have two systems which I upgraded from 6.2 to 7.0. After the upgrade I was no
longer able to mount CD-rom's, got the errormsg:
mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
or too many mounted file systems
(aren't you trying to mount an extended partition,
instead of some logical partition inside?)
No atomount worked.
Then I realised that if I created a new user, this user had no problems.
Automount allso worked fine for users created after the upgrade to 7.0.
Now I have two systems where old (pre 7.0 created) users, including root, are
unable to use CD's, but where the newly created users have no problems.
In his comment, crutcher mentioned a file called /etc/auto.mnt. I am not able to
locate this file on any of my two systems.
Couple of questions:
Are you running autofs?
If so, please post copies of every /etc/auto.*
Do you have a line similar to this in your fstab?
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro 0 0
I don't no, will need to reboot to RH7. But I did found what was causing the
problem: If I press the physical open/close button when a Cd was mounted and
inserted another Cd, I could not read all of it's contents, but if I right
clicked on the CDROM icon and eject the Cd from the desktop and then reinserted
the Cd I could read it fine. So for now I'm staying clear of the open/close
button. Try it on your system and let me know if you can duplicate the error.
PS. With previous versions of RH I could not open the CDROM without unmounting
Hope this helps
sounds like this was an file manager interaction, and not a cdplay problem
