Bug Description

Binary package hint: linux-source-2.6.20

The latest daily build of ubuntu server (feisty) and Herd 4 of Feisty desktop does not detect the CD drive on an Intel DG965RY motherboard. I've updated the BIOS to Intel Feb. 27 version, tried switching the drive behavior in the bios to Native Sata, Legacy, IDE and AHCI mode -- all with the same result. The CD drive is a straight IDE one taken directly from a working Edgy machine, so it's unlikely to be broken. Just in case, I tried a brand new CD drive with the same result. It's the only IDE in the machine. The three hard drives are SATA.

I've tried the following boot options: all-generic-ide, acpi=off, pci=nommconf -- in different combinations. Neither the desktop nor the server install finds the CD drive (although, obviously, they boot off it OK).

The only clue I've been able to find is in lspci:

02.00.0 IDE interface: Marvell Technology Group Ltd. Unknown device 6181 (rev b)

That's the only "Unknown" in lspci's output.

You appear to be in the same boat (first hit on Google) as a Gentleman who

Some background to how Marvell ended up on an all Intel board:

Further searching:

ICH8 (i965) doesn't have IDE ports, only SATA. Except nobody sells SATA
optical drives; so at the last minute Intel hacked into somebody else's
(Marvell's) legacy IDE controller so that people can still use CD/DVD drives
and the whole setup has ...some issues.

I was able to get this working by putting the IDE CD/DVD drive into a USB enclosure. But this is going to be a common chipset going forward, so it would be good to get this fixed.

Just a note that 2.6.20-11-server appears to have solved this issue for me. The CD/DVD writer is now detected and working for me.
