From Bugzilla Helper: 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 As additional information, the contents of several files in the /proc directory and others are included: ------------/proc/cpuinfo-------------------------- processor : 0 vendor_id : AuthenticAMD cpu family : 5 model : 8 model name : AMD-K6(tm) 3D processor stepping : 12 cpu MHz : 451.024 cache size : 64 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr mce cx8 pge mmx syscall 3dnow k6_mtrr bogomips : 897.84 ---------------------------/proc/devices--------------------------------------- Character devices: 1 mem 2 pty 3 ttyp 4 ttyS 5 cua 6 lp 7 vcs 10 misc 14 sound 29 fb 36 netlink 109 lvm 128 ptm 136 pts 162 raw 180 usb Block devices: 1 ramdisk 2 fd 3 ide0 9 md 22 ide1 58 lvm -----------------/proc/ioports------------------------------------------------------------ 0000-001f : dma1 0020-003f : pic1 0040-005f : timer 0060-006f : keyboard 0070-007f : rtc 0080-008f : dma page reg 00a0-00bf : pic2 00c0-00df : dma2 00f0-00ff : fpu 0170-0177 : ide1 01f0-01f7 : ide0 0213-0213 : isapnp read 02f8-02ff : serial(auto) 0376-0376 : ide1 0378-037a : parport0 03c0-03df : vga+ 03f0-03f5 : floppy 03f6-03f6 : ide0 03f7-03f7 : floppy DIR 03f8-03ff : serial(auto) 0778-077a : parport0 0a79-0a79 : isapnp write 0cf8-0cff : PCI conf1 f000-f0ff : Realtek Semiconductor Co., Ltd.

After 1 more unsuccessfull reinstall, the cdrom drive started working on the 3rd trial...... no explanation found.
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........
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
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 same.
Could you please type "linux ide=nodma" on the first syslinux prompt and tell me if that helps ?
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.)
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.
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.
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 persists. 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/
