[Bug 27316] Re: Plextor DVD-RW drives do not detect DVDs properly until an audio CD is inserted

Problem persists with Dapper - on a Shuttle SD11G5 with a PX716SA
(1.09).

Burnt ISO-DVDs are mounted fine, where as UDF DVD-ROM fail:

dmesg:
> ata3: translated ATA stat/err 0x51/54 to SCSI SK/ASC/ASCQ 0xb/0 0/00
> ata3: translated ATA stat/err 0x51/54 to SCSI SK/ASC/ASCQ 0xb/0 0/00
> ata3: translated ATA stat/err 0x51/54 to SCSI SK/ASC/ASCQ 0xb/0 0/00
> sr0: CDROM (ioctl) error, command: <6>Read TOC/PMA/ATIP 43 02 0 0 00 00 00 01 00 0c 00
> sr: Current [descriptor]: sense key: Aborted Command
> Additional sense: No additional sense information
> cdrom: This disc doesn't have any tracks I recognize!

Meanwhile, the consoles are flooded with the status report of the
quality test unit of the drive:

> ata3: translated ATA stat/err 0x51/24 to SCSI SK/ASC/ASCQ 0xb/0 0/00
> ata3: translated ATA stat/err 0x51/24 to SCSI SK/ASC/ASCQ 0xb/0 0/00

Personally, I don't favor the 'firmware bug' theory, as XP reads DVD-ROM
fine and downgrading doesn't make any difference.
