disk controller/device errors?

[Jeffrey Ross]

I've been getting a lot of these errors in my /var/log/messages file:

If I'm reading correctly the two devices its complaining about are the 
CD and DVD drives in the system:

Host: scsi7 Channel: 00 Id: 00 Lun: 00
  Vendor: BENQ     Model: DVD DD DW1620    Rev: B7W9
  Type:   CD-ROM                           ANSI  SCSI revision: 05
Host: scsi7 Channel: 00 Id: 01 Lun: 00
  Vendor: SONY     Model: CD-RW  CRX175E   Rev: 1.0j
  Type:   CD-ROM                           ANSI  SCSI revision: 05

the controller is:

03:00.0 IDE interface: Marvell Technology Group Ltd. 88SE6101 
single-port PATA133 interface (rev b1)
