When switched to command line, repeats "sr0: CD-ROM device not ready" over and over

paradoxdruid · 10-20-2003, 06:02 PM

Hello all, and thank you in advance for any help.

I got into Debian via Knoppix, but have since upgraded and what-not, so my system is a fairly standard Debian setup, running testing with large chunks of unstable.

I think a recent apt-get upgrade (performed using standard debian.org apt sources) messed up my system though. When in KDE, everything works fine. Konsole also works fine. But when I switch to a command line window, it displays:

sr0: CD-ROM device not ready. Make sure there is a disk in the drive.

Over and over, scrolling up the page slowly. They don't display until I switch over- I can still see, for example, the system start information on the first terminal.

When I put in ANY CD into my CD drive, the errors stop. However, they restart if I subsequently remove the CD.

I have checked- There isn't an error in my fstab file, which is the only thing I could think of off-hand. What else could be causing this strange behavior?

Thank you in advance for any help.

Check and see if you have an automounter running. ( I hate the thing, for exactly the problem you describe, so I've always made a point NOT to install it.) I also have just begun experimenting with Debian (via Libranet), so I'm not sure what the daemon is called in Debian. I'm pretty sure it has "auto" in it, though, so try "ps -ef | grep auto". If you find one, kill it while you're having the problem. If the messages stops, that's your culprit.

What's happening is that its trying every few seconds to mount a CD, so that you don't manually have to enter a mount command. Mandrake has (or had, I know it's been in and out, and I don't know its current status) a thing called "supermount" which made it work a lot like Windows. If the CD is in, its mounted, and if you hit the button, it automatically unmounts it and ejects the CD.

Automount does NOT do that, and it constantly bitches if it can't find a CD, so I shot mine between the eyes.

I think you've nailed the problem...

However, I can't find a process running by grepping for anything like "auto" or "mount".

Any other suggestions on killing this thing? I tried googling for names of automount daemons in debian, but seems like all have mount or auto in their name... hmmm. When I grepped top for "daemon", all it found was atd and portmap.

Thank you in advance for any additional help.

here's the output of a ps -e

It is called autofs4 and it is being loaded from /etc/modules as autofs so you would want to comment that out, it however works perfectly on my machine.

Also I notice in the list of processes you have running that kscd is there I have had nothing but problems with it so much so that I un-installed you may want to see if that is causing this problem, checking my list of processes running you see that automount is running so I doubt if that is your problem it is not even listed in your processes listed.

Thank you very much, Happy Tux!

I commented out the autofs line, rebooted, and it's working like a charm.

Seems strange that it works when there was nothing in the processes list I guess it is time to chalk another up for the computer gremlins. Good to hear you got it going BTW and nice to see that you posted the solution in the Knoppix forum for your question there as well.

paradoxdruid · 10-21-2003, 04:22 PM

Actually, you were right.. it was too strange to be true.

I did comment out autofs, but I might restore that... it seems to have had no effect.

KsCD, however, was the source of my woes. You were right to warn me against it.

That's what I thought I had nothing but problems with it, at least you got the problem tracked down now.
