FC4 hangs when cd rom is inserted

[aribender]

Hi,

My problem is that whenever I insert a cd rom on my recorder, the kernel hangs giving an error, and I have to restart my computer. Same thing happens if I try to restart with a cd inserted.

Please, if you need more info (like some log, or anything), tell me how to get it, as I am a newbie.

Thanks, Aribender

What is the error message?

[aribender]

The last thing I see is the screen full of messages like:

[<c0103c0e>] common_interrupt+0x1a/0x20
(...)
[<c0103a51>] syscall_call+0x7/0xb

If you could tell me where all that is logged, then I could send the whole error, but It's more than one screen (so I cannot see it all).

The error message should be logged in /var/log/messages.
Please also post your type of hardware (mainboard, chipset on it, ...)

[aribender]

There's nothing starnge (from my newbie point of view) on the /var/log/messages
The first few lines with time after the time I put the cd on are:
***************************
Jul 13 15:39:20 localhost syslogd 1.4.1: restart.
Jul 13 15:39:20 localhost kernel: klogd 1.4.1, log source = /proc/kmsg started.
Jul 13 15:39:20 localhost kernel: Linux version 2.6.12-1.1390_FC4 (bhcompile@decompose.build.redhat.com) (gcc version 4.0.0 20050519 (Red Hat 4.0.0-8)) #1 Tue Jul 5 19:58:55 EDT 2005
************************
which I think it's my forced reboot after the hang.

Mi hardware:

Motherboard msi k7n2gl (chipset nforce2). CPU athlon xp 2000. One more thing that may be usefull is that this very same computer (I didn't change any hardware modifications) worked perfect with fc4 a few day ago.

All my problems started after a fresh reinstall (formatting my hd, so it was really a fresh installation). The only few things I did after that were upgrading (via up2date), installing a couple of packages (harmless packages, like kile, octave, and a few other I needed, but nothing hardware related), and following this howto to get mp3 to work:

That's all I did.

More insight into my problem, so maybe someone can help.

If I insert the cdrom without mounting it, it does not crash. Even more, I can go te /dev , do a 'cat hdd' an see the contents of my cdrom. However, when I mount it (no matter if I do it manually or kde does it automatically), that crash I said before happens.

So it has to be something during the mount. Maybe reinstalling some packages, but I don't know what packages...

Thanks again, Aribender

Another thing I just found out. If I mount the cd with:

mount -t iso9660 /dev/hdd /media/cdrecorder

it works great. However, if I mount it with mount /media/cdrecorder it hangs. So it should be something in the fstab, but I'm no sure about what. Here's my fstab for that device:

/dev/hdd /media/cdrecorder auto pamconsole,exec,noauto,managed 0 0

What should I change there?

Thanks, Aribender

Just a quick thought ... does turning off the hal daemon result in any change ? As root try:

/etc/init.d/haldaemon stop
mount /media/cdrecorder

change auto to iso9660

Hi,

Well, the hal daemon had nothing to do. It still hanged upon insert of a cdrom. What did work was to change manually the fstab (as Mat said), and doing " chattr +i /etc/fstab " , so fstab doesn't change every time y reboot.
Anyway, I still don't know why happened that, but It's not urgent anymore.

Thanks to everyone!

That's good to know. I had the same problem on another machine recently. Mysteriously only the dvd drive showed this behavior, the dvd burner was unaffected .

I found someone with a solution, instead of the workaround of mounting as iso9660 (which, as I found out later, doesn't always work).

It worked perfect to me.
