can't open cdrom!

aspartat · 03-15-2005, 10:18 AM

Hallo,
i have installed slackware-10.1 with linux-2.6.11, as far as good! The problem is that if I am in kde (3.3.2), mount a cd and later umount it, I can't open the cdrom!
Also a eject -r does not work.
After giving a eject -r dmesg shows this:

program eject is using a deprecated SCSI ioctl, please convert it to SG_IO

After logging out from KDE, pushing the cdrom-button works like it should and the cdrom opens.
This is realy crazy, so If you have a good hint for me...
Why this does not work in KDE?

regards Thorsten

It almost sounds like something is still holding the lock on the door. Are you certain the umount succeeded?

yes, a mount shows that the cdrom isn't mounted.

If you have the lsof utility, try "lsof | grep /dev/DEVICE" to see if anything else is working with it.

You're right,
I found this with lsof

kio_audiocd 4546 corban 12r BLK 22,0 3787 /dev/hdc

if I made a killall -9 kio_audiocd I can open the drive.

But this nerves a little bit, why this process hangs on an unmounted device??

Is there a workaround for this?

thanks in advance Thorsten

There's a bug in KDE-3.3.2, where a process "kio_audiocd" locks a drive for a few minutes, also if a Data-CD is mounted, so it's not possible to eject it. In that script this process will be killed after 10 seconds. I hope this bug will be removed in the next version of KDE.

thank you very much!

Not sure how helpful it is. But at least you know someone else has seen this. Their solution seems to be much like yours. KILL.
