Since the upgrade from 2.6.x+devfs to 2.6.12r10+udev cdparanoia stops working. cdparanoia say that I don't have a CDROM and that's the problem. (I'm talking about a real SCSI device and not some ATAPI emulation.)
I copied the kernelconfigs from the last working release to the current release of my kernel so I don't think I'm missing any modules here. Mounting a data cd is working perfectly:
% df | grep cdrom
/dev/cdrom 699M 699M 0 100% /tmp/cdrom
Reading from the CD is okay too:
% xxd /dev/cdrom
[...]
Using cdparanoia on an audio CD is not working:

The device node is the same:
% dir -al /dev/sr0
brw-rw---- 1 root cdrom 11, 0 Sep 7 2005 /dev/sr0
cdparanoia don't support any use flags so I can't do a wrong thing here!
I've tried all the stuff as root.
What is the problem here? Is this a known issue (https://bugs.gentoo.org says no)? Any alternatives to cdparanoia? |

Thanks for the answer!

1) The kernel has generic SCSI support compiled in (or the generic module available). Generic SCSI support does *not* mean only SCSI or SCSI CDROM.
2) Those using ATAPI CDROM drives with IDE-SCSI emulation must *not* have ATAPI CDROM support included. ATAPI IDE-SCSI emulation users must have all the appropriate SCSI support selected.
3) The generic SCSI devices (/dev/sg*) must exist and be accessible. Check that permissions on the device entries allow user or group read *and* write access (it's safest to grant user or group access only to the device matching the cdrom).

1) I don't know which kernel modules are really necessary. The SCSI-CDROM is working fine with data CDs so I think I the kernel is fine. Are there any extra modules for audio cds?
2) My CD is not an ATAPI CDROM. It's a real scsi device and I'm working as root.
3) /dev/sr0 is in good condition:
% mount /dev/sr0 /tmp/cd
mount: block device /dev/sr0 is write-protected, mounting read-only
Any other hints? |

As far as I understand, even if you've got a genuine SCSI cdrom, you still have to enable "Device Drivers->SCSI device support->SCSI generic support". This will make sure that a /dev/sgX device is created for your cdrom, which is needed for cdparanoia to work.

| '/usr/share/doc/cdparanoia-3.9.8-r2/README.gz' gave me the answer. The not loaded module 'sg' was the solution to the problem. After a 'insmod sg' everything was fine. |

So, different source, same solution.  |
