Bug 135669

Version:            (using KDE KDE 3.5.5)
Installed from:    Gentoo Packages
Compiler:          gcc version 4.1.1 (Gentoo 4.1.1) 
OS:                Linux

When I insert an audio cd on my computer, I get a pop-up notification asking me what to do. When I choose "open in a new window", so I can use the audiocd kioslave to rip the tracks to my hd, after a while I get an error popup[1] telling me it couldn't find any devices and advising me to run the command 'cdparanoia -svQ' to check if any devices are found.

Running the above command returns the following:

$ cdparanoia -svQ

Checking /dev/cdrom for cdrom...
        Testing /dev/cdrom for SCSI interface
Error trying to open /dev/sr0 exclusively (Device or resource busy). retrying in 1 second.

Error trying to open /dev/sr0 exclusively (Device or resource busy). retrying in 1 second.
....

So the problem is cdparanoia needs exclusive access to the device, but it's not being able to have it. Here's lsof output from right after the error is shown:

# lsof /dev/sr0
COMMAND    PID     USER   FD   TYPE DEVICE SIZE NODE NAME
kio_audio 4359 gmichels   15r   BLK   11,0      4362 /dev/sr0
kio_audio 4360 gmichels   14r   BLK   11,0      4362 /dev/sr0

However, after about 5-10 minutes of inactivity, I get another "disc inserted notification", as if I had inserted a new disc, but I haven't removed or inserted any discs or whatever. And now, if I do the "open in a new window" command, it works as expected (the mp3, vorbis, flac, etc folders are shown) and I can succesfully rip the audio cd.

The output of lsof when it succesfully opens the cd:

# lsof /dev/sr0
COMMAND    PID     USER   FD   TYPE DEVICE SIZE NODE NAME
kio_audio 4360 gmichels   14r   BLK   11,0      4362 /dev/sr0

And when the ripping process is ongoing:

# lsof /dev/sr0
COMMAND     PID     USER   FD   TYPE DEVICE SIZE NODE NAME
kio_audio 10025 gmichels   15r   BLK   11,0      4362 /dev/sr0
kio_audio 10061 gmichels   14u   BLK   11,0      4362 /dev/sr0
kio_audio 10061 gmichels   15r   BLK   11,0      4362 /dev/sr0

lame      10206 gmichels   15r   BLK   11,0      4362 /dev/sr0

To be honest, it's the first time I'm trying to use the audiocd ioslave on this computer, so I can't tell if it worked with previous versions.

I'm using cdparanoia-3.9.8 with the SG_IO patches applied, as I'm on 2.6.18. Also, it's a SATA DVD-RW, using libata.

Please ask if you need further information.
