Default disk controller/device errors?

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

Aug 3 05:13:19 wisdom kernel: ata7.01: exception Emask 0x0 SAct 0x0
SErr 0x0 action 0x2 frozen

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)


TIA

You'll also want to tell the list about things like:

Are those errors happening all the time? i.e. You see them repeatedly
throughout the log, and you can't see any reason why (such as the follow
up questions).

Do they happen at times when there are discs in the drives, or not?

Do they just happen after inserting a disc, and the system is trying to
work out what to do about it?

Do they happen while reading discs?

Do discs apparently behave normally, despite the error warnings?

I realized that after I sent the message...

system is Fedora 9 - x86_64 kernel 2.6.25.10-86.fc9.x86_64.

The errors are pretty regular, almost every 56 minutes and while the DVD
and CD disks are idle. I don't use them (the CD/DVD rom drives) that
often so I don't know for sure if its affecting their use, I'll try
writing some files out and see what happens, I'll try to time it during
the next expected "event."


The system disks are SATA drives and are not associated with those
device numbers.

With discs in the drives, or not?

I see occasional errors when there's discs in the drives (typically
associated with inserting a disc, when it first tries to read it), but
none when there's not.

Drives are currently empty and the errors continue.

Could be power related problems. Is your system heavily loaded with many
hard drives, game card etc. This normally is SMPS related.
