Testing the new libata ICH PATA drivers.  There's one PATA port on this
chip, and I've got two optical drives connected to it.  The master drive
fails to detect.  The slave detects and works properly.

Can you test 2.6.20.1 and post full dmesg?

Here's 2.6.20.2...  No ACPI errors, but still doesn't detect both drives.

Please apply the attached patch and see if it works.  If it works,
please post the result of hdparm -I /dev/srX of the optical drive.  Thanks.

Okay, here ya go:
