I have an IBM server with a SATA controller listed as:
0000:00:1f.2 IDE interface: Intel Corp. 6300ESB SATA Storage Controller (rev 02)
Debian's 2.6.8 kernel with libata works fine, except that the CDROM
(which is on a PATA port) does not appear as a SCSI device. It's also
not seen by the regular IDE driver, because ata_piix has already
grabbed the i/o resources--I get:
ide0: I/O resource 0x1F0-0x1F7 not free.
ide0: ports already in use, skipping probe
ide1: I/O resource 0x170-0x177 not free.
ide1: ports already in use, skipping probe
Is there any way to get ata_piix to register my CDROM, or
alternatively to have the regular IDE driver handle it?
This seems to be a known problem (it's filed as a Debian bug)--is it
fixed in 2.6.9-rc4? I had a look at the -rc4 patch but couldn't tell
from the diff whether there's anything CDROM-related in there...
Thanks,
Doug

Well, two things are going on:
You may need to set CONFIG_BLK_DEV_SATA (or unset it) depending on your
configuration.
Once you get past that, you need to apply the latest libata patch to fix
a related combined mode bug.

I will look into this.

I will probably wait until this trickles into a Linus kernel--I don't
have an immediate need for the CDROM (and I can boot 2.4 if I have
to).
Thanks very much for the response!
