Comment:
OK so it looks like Ralph may be on the right track, at least for my
hardware. Here's what I did:

switched inittab to boot at runlevel 1

inserted cdrw into drive. No kernel error messages produced.

Blanked the cdrw with cdrecord as follows:

cdrecord -blank=fast

This worked perfectly as far as I could see (the burn flashing light
operated normally and the command ended normally and no kernel error
messages were produced).

Next I switched the runlevel to 2 and executed /etc/init.d/gdm start
This is a gnome command but probably not important (?). I then logged into a kde session.

I then opened a terminal inserted a cdrw and executed

 cdrecord -blank=fast

Again no kernel error messages were produced and everything appeared to
function normally.

I then tried a full iso burn with

cdrecord -dao -v -data *.iso

(* was some random iso file I had lying around).

No kernel error messages were produced and the burn appeared to work. I
inserted the burnt cdrw into my other cd drive (an ide dvd/cd drive) and
looked at it using konqueror. several kernel error messages were
produced:

[4297863.278000] ide: failed opcode was: unknown
[4297863.278000] end_request: I/O error, dev hda, sector 1418944
[4297863.278000] Buffer I/O error on device hda, logical block 354736
[4297870.386000] hda: media error (bad sector): status=0x51 { DriveReady SeekComplete Error }
[4297870.386000] hda: media error (bad sector): error=0x30 { LastFailedSense=0x03 }
[4297870.386000] ide: failed opcode was: unknown
[4297870.386000] end_request: I/O error, dev hda, sector 1418948
[4297870.386000] Buffer I/O error on device hda, logical block 354737

One html file on the cd was difficult to read during these error
messages.

A cdr version burnt on knoppix appeared fine however with no such error
messages and the html file above was fine.

I then opened k3b and unfortunately it could not find my cd writer and
kernel error messages like in previous posts here were produced.

Next I looged into gnome and retried the terminal command above. Now
unlike a fresh gnome login they both (a blank and a burn) appeared to
work. HOWEVER the following kernel error messages were produced:

[4297939.701000] scsi: unknown opcode 0xe9
[4297939.701000] scsi: unknown opcode 0xed
[4297940.533000] scsi: unknown opcode 0x01
[4298073.702000] scsi: unknown opcode 0xf5
[4299326.968000] scsi: unknown opcode 0xeb


The first three during the blanking and the last two during the burn.
Following the burn I placed the newly burnt cdrw into the other drive and now no kernel error messages were produced and the html file mentioned aboved opened fine. The cdrw did not mount automatically in gnome however this may be another issue.

OK this all looks rather mysterious to me. Any suggestions Ben or Ralph?
