User-Agent: Mozilla/4.5 [es] (WinNT; I)

After successfully installing wolverine from the cdrom drive and rebooting the system, this same cdrom drive cannot be mounted.

Reproducible: Always
Steps to Reproduce:
1.Install Wolverine from cdrom
2.reboot system
3.try to access cdrom

Actual Results:  after rebooting, and trying to mount the cdrom, an error message, saying that no filesystem type is given appears.
The filesystem defined in /etc/fstab for the cdrom is "auto".
After changing this from "auto" to "iso9660", another error message appears, saying that the device could not be accessed and suggesting that 
it maybe is the cdrom drive that should be accessed through the "ide-scsi" module.

The cdrom drive in question is a plain ATAPI 50x cdrom.  It works fine during the install and on other OSes and also had no problems on 
RedHat 6.2

Expected Results:  Drive should be accessible

Comment 1 Geert Dobbels 2001-04-10 09:49:37 UTC
After 1 more unsuccessfull reinstall, the cdrom drive started working on the 3rd trial...... no explanation found.

Comment 2 Geert Dobbels 2001-04-12 14:22:07 UTC
Unfortunately, it only worked once......  after another reboot it could again
not be mounted any more.
New reinstallation of wolverine dit not help.  As a check, I reinstalled Linux
7.0 and there the cdrom worked without any problem........

Comment 3 Arjan van de Ven 2001-04-18 14:44:42 UTC
Could you try booting a recent kernel (2.4.2-0.1.40 or 2.4.2-2) and use
"ide=nodma" to see if that helps ?
(if so, please give the output of "cat /proc/ide/hdc/model" (1))

(1) change "hdc" to the appropriate device of your cdrom drive

Comment 4 Geert Dobbels 2001-05-07 14:50:35 UTC
Since I am not a Linux guru, and have no experience at loading this or that
specific kernel, I decided to give seawolf (redhat 7.1) a try, with the
following (dissapointing) results:
Booting from the CDROM, the typical textscreen appears where one has to choose
between new installation, upgrade, expert mode ..... choosing new installation,
the next screen appears with the pinguin and all the initialisation messages
(apparently without errors in them).  Then the user is asked for the
installation language, the keyboard type and if he installs from cdrom or from
harddisk.  After answering CDROM, I receive a message saying that the system
could not find a Red Hat Linux CDROM in my drive, and I cannot go on with the
installation.  To be sure that the data on my CD was downloaded correctly, I
repeated the download from another site, burned a new CD, but the result was the

Comment 5 Arjan van de Ven 2001-05-07 20:58:15 UTC
Could you please type "linux ide=nodma" on the first syslinux prompt and
tell me if that helps ?

Comment 6 Geert Dobbels 2001-05-08 08:33:43 UTC
I'll try your suggestion as soon as I can, and tell you the results.

What I tried was switching off ide DMA in the Bios configuration, but this didn't help.

In the meantime, allthough the concerned CDrom drive works fine under windows (and worked fine under RedHat 6.2), I started to get suspicious about 
this drive.  After several unsuccessfull attempts to install Redhat 7.1 from it, I disconnected it from the PC and built in another CDrom drive which let me 
install 7.1 without any problem.  After installing 7.1, I again swapped the drives and build in the old one that gave me problems, and now I can startup 
Linux and access this CDrom drive without any problem !!!

(The concerned drive is "Afreey CD-2050R", an 50x atapi CDROM.)

Comment 7 Arjan van de Ven 2001-05-08 08:38:54 UTC
Most "bad" cdromdrives I've seen so far only misbehave under high load;
but you proved it is related to this one drive, which is a good thing.

Comment 8 G. Bersano 2001-05-09 13:15:19 UTC
Same problem here: ... the user is asked for the installation language, the
keyboard type and if he installs from cdrom or from harddisk.  After answering
CDROM, a message says that the system 
could not find a Red Hat Linux CDROM in the drive.
Test machines: COMPAQ PROSIGNIA with hdc Compaq CRD-8402B; COMPAQ ARMADA E500
with hdb CD-224E.
Tried with 'linux ide=nodma' too, same result.
Copied iso images on the hard disk and installation went smooth; after install
CD-ROM works flawlessly.

Comment 9 Bugzilla owner 2004-09-30 15:38:57 UTC
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
