IIRC that's what I've got here, too. 8,8,24 it says on the front, and it's
a yamaha...

Erm, is there any reason why it would be writing multiple tracks? What have
you specified as a set of files to be written?

So it's somewhere between kernel and cd-writer inclusive, excluding the
laser. Sounds like it's in the SCSI neck of the woods.

Weird. What make scsi card do you have, and what version of the kernel are
you using?

Me, I use a powerbook's built-in MESH scsi controller, with kernel 2.4.4
(it's the only one of the 2.4.x series I've managed to make compile on
ppc!). But that works; I've also had success with an Initio/adaptec card on
x86.

He's probably writing an audio CD.

Well I should have posted more details...it was late:-)

My card is Adaptec 29160 with firmware v. 3.10 (Card normally ships
with 2.54, flashed it, it failed, sent card in etc. etc. etc.)

Kernel is 2.4.3-12 Redhat 7.1.  Program is Xcdroast (Front end to the usual
Linux CD writer tools)

On later thaught I think that the kernel shipped with Redhat worked OK
but I am not sure.  It certainly is all a mystery.
