Laptop SATA CD drive not detected with 2.6.16


Upon compiling the 2.6.16 kernel from kernel.org I lost the ability to mount CDs with the SATA CD drive of my laptop. I get the following error when trying to mount:
Code:
mount: special device /dev/scd1 does not exist
2.6.16.20 also fails the same way.

There's nothing resembling a CD drive entry under /dev. Should I make one with mknod? If so, how? Any other ideas?

(The drive works with the 2.6.15-23 Ubuntu kernel; it's not a compatibility issue.)

You need to enable SCSI in your kernel configuration. This is because SATA and USB require it.

It's enabled in the config I imported from my default kernel with which the drive works, and my SATA HD is working with the new kernel. What should I set CONFIG_SCSI_SATA and CONFIG_BLK_DEV_IDE_SATA to? Right now I have:

Code:
CONFIG_SCSI_SATA=m
# CONFIG_BLK_DEV_IDE_SATA is not set

That's probably because SATA HDs use the SCSI interface.

I can only assume that SATA CD drives require that option to be enabled. I don't know, I've never had to configure a SATA CD drive.
