cdparanoia-3.9.8-r3 works, -r5 doesn't. My system, dmesg: ... libata version 2.00 loaded. ata_piix 0000:00:1f.2: version 2.00 ata_piix 0000:00:1f.2: MAP [ P0 P2 IDE IDE ] ... ata2: PATA max UDMA/100 cmd 0x170 ctl 0x376 bmdma 0x18B8 irq 15 scsi1 : ata_piix ata2.00: ATAPI, max UDMA/33 ata2.00: configured for UDMA/33 Vendor: HL-DT-ST Model: DVDRAM GMA-4082N Rev: HA01 Type: CD-ROM ANSI SCSI revision: 05 ... with /dev/cdrom -> sr0 and no SCSI generic.

Load the sg driver, SG_IO has bad behaviour on real SCSI and some pata drivers, and it's not maintained officially, so it has been removed from -r5.
