I would think it's either your CD media or a faulty cdrom drive.

Try mounting the cdrom outside of Gnome. Go to runlevel 3 "telinit 3" to get out of X. If you still have the problem, it is a bad cdrom drive. If you don't it is a bug in your DE.

ok so i went to runlevel3, tried to mount it. and i got a bunch of timeout crap.

hdb: registering filesystem
hdb: timeout waiting for DMA
hdb: timeout waiting for DMA
hdb: ATAPI reset complete
hdb: Drive not ready

so think its mabey.. erm.. a old cd-rom that is just broke? lol or is this fixable.

If it's "suddenly" stopped working (was working before, which I'm assuming was how you got Fedora onto the machine) and you haven't been in there mucking about with the hardware, I can only think of two things:

1) It's a cabling fault (either the cables went bad or you moved the computer and one got dislodged)


2) The CD-ROM just died on you.

Try a couple of different CDs, especially those that come from boxed, professional applications. If you can't mount any of them, then the best soution is to just go buy a new one. They run about $20US and you get the cable, too.

or better yet you can get one from eBay! a used one working in good condition will probably cost you $1.99 + shipping !

good luck!

I have the same problem as sponge:

After I installed Fedora Core 1 I was able for a while to mount /mnt/cdrom and /mnt/cdrom1.

The I installed apt from fedora.us, did some normal work, and after a while mount /mnt/cdrom made my system freeze - no ctrl-alt-del or ctrl-alt-backspace works. The same happens in X and in concole mode.

I tried to install Fedora several times and always had the same problem - but always in different situations. So I can't say it happend after doing something special (installing some piece of software etc.). But the cdrom works for a new install and short after it, and it works fine under win98se. So it is not a hardware fault.

Any help appreciated.

I have the same issue. Rom has worked before in other install of fedora 4. I think it might be an issue fstab. I may just install again?

I had this problem with a homemade DVD. Turns out the DVD was the problem, the drive would mount a regular DVD just fine. I did however notice that my fstab thought my drive was located somewhere it wasnt. :(.

I had this exact problem when I installed FC4 on my wife's computer. I came to the conclusion it was the motherboard, an Asus P4P800S-X. I installed FC2 and it went perfectly. If you have a P4P800xx, search the web for "P4P800 linux"

I ghosted the system back to windows CD burner works fine; I have the same setup in another computer with the same brand (Sony). It works fine! The fstab looks the same the only difference is this is a AMD 64. I have had problem with the first install because the kernel on that cd did not support my system, by doing a text install and running YUM to upgrade the kernel I was able to get the system installed. Now I am wandering if I should recompile the kernel for my computer?

AMD 64 x2 4200
4 GB of ram
I have never done this an am a little reluctant.

The lockup is acting like an irq conflict. Is their a way to see the resource being used on the mother board?

I think it is 'hdc lost interrupt' problem
disable PCI IDE interrupt sharing

When I try /mnt/cdrom the system freeze and I can hear the disc spinning over and over.
I had to install Fedora by hard disk because the installer never could mount hdc.
But in Windows my cdrom drive works perfectly.
What happens??
Thank you.
