Well, it's good to hear that you don't think my drive is failing (sure
hope it's not failing!)

Yeap, it's your DVD drive.

I posted the full dmesg in reply to Alan in
http://lkml.org/lkml/2008/12/19/30.

Ah.. oops, missed the other messages. Sorry.

Also, more information about my computer can be found at:
http://jdserver.homelinux.org/bugreports/
If you need me to run anything else not found in the above links then
let me know.

Ah.. strange. The command protocol is ATAPI_PROT_NODATA and the drive
should be setting DRQ to receive CDB but it's not doing that.
Strange. It could be that the drive is a little bit tardy with DRQ -
ie. setting DRQ after clearing BUSY and ata_piix is now successfully
hitting the small window for some reason.

Does the attached patch make any difference?

Thanks.

Ok, I applied your patch. Unfortunately, it didn't fix my problem.
I now get a different, but similar message; not sure if it happens less frequently - still often though.

What changes happened between .27 and .28 could've caused this?
Anyways, below is what I get now (with your patch), including the frequency of occurrence.
