[paranoia] cdparanoia 9.7 crash on redhat 6.1

[Ian Collinson]

cdparanoia 9.7 is crashing often (mid rip) on our boxes (RedHat 6.1).  Once
it has crashed, then running it again blocks forerver (strace shows it
blocks on open("/dev/sg0"...)).

See below:

Checking /dev/cdrom for cdrom...
        Testing /dev/cdrom for cooked ioctl() interface
                /dev/scd0 is not a cooked ioctl CDROM.
        Testing /dev/cdrom for SCSI interface
                generic device: /dev/sg0
                ioctl device: /dev/scd0
                CDROM sensed: ASUS CD-S500/A 1.5D 

Checking for SCSI emulation and transport revision...
        Drive is ATAPI (using SCSI host adaptor emulation)

Checking for MMC style command set...
        Drive is MMC style
Verifying CDDA command set...
        Expected command set reads OK.

Looking at revision of the SG interface in use...
        New style SG with scatter/gather memory management
        DMA scatter/gather table entries: 256
        table entry size: 32768 bytes
        maximum theoretical transfer: 3566 sectors
        Setting default read size to 13 sectors (30576 bytes).

Any idea why?
