Well it is there:

ATA: abnormal status 0x80 on port 0x000140df
ata1.00: configured for UDMA/33
ata3.01: NODEV after polling detection
ata3.01: revalidation failed (errno=-2)
ata3: failed to recover some devices, retrying in 5 secs
ATA: abnormal status 0x7F on port 0x000140df
ATA: abnormal status 0x7F on port 0x000140df
ata3.01: configured for UDMA/133
SCSI device sda: 234441648 512-byte hdwr sectors (120034 MB)
sda: Write Protect is off
sda: Mode Sense: 00 3a 00 00
SCSI device sda: write cache: enabled, read cache: enabled, doesn't
support DPO or FUA

just FYI a macbook pro has a sata disc + a dvd drive registered
as /dev/sda and /dev/scd0 driven by ata_piix:

dmesg | grep ata_piix 
ata_piix 0000:00:1f.1: version 2.10ac1
scsi0 : ata_piix
scsi1 : ata_piix
ata_piix 0000:00:1f.2: MAP [ P0 P2 XX XX ]
ata_piix 0000:00:1f.2: invalid MAP value 0
scsi2 : ata_piix
scsi3 : ata_piix
