ATAPI drive and libata / 3114 problems

ATAPI drive and libata / 3114 problems

[Tobias Ottmar]

Hi there,
I have a problem and hope that you might have a clue what I could try to
get my setup work. It's like that:

I have a regular PATA LG DVD ROM drive. I want this drive to be
connected to my Silicon Image 3114 PCI Controller and have therefore
bought a SATA/IDE Adapter which I mounted to the CDROM drive.

The 3114 works okay for my two "real"-SATA Maxtor harddisks, but for the
DVD drive it won't work. What troubles me is that the driver finds the
drive but does not attach a device to to it (at least it seems to me to
be like this).

This is the output of dmesg:

And that's it - shouldn't it be assigning /dev/sdc to my DVD drive?

I am running Fedora Core 2 with a self-compiled 2.6.9 kernel, I have
also tried applying the two patches for libata from
/pub/linux/kernel/people/jgarzik/patchkits/2.6/ but the problem is still
there.

I hope I did make myself clear, please ask again if I didn't!

Many thanks in advance
