Hello!

As reported by John Williams and others like in
http://www.mail-archive.com/linux-ide@xxxxxxxxxxxxxxx/msg03088.html
I too have a problem with 2.6.20.1 using ata_piix not detecting the
CD-ROM any more. Applying the patch from
http://lkml.org/lkml/2007/2/12/24 did not help, but additionally
applying
http://readlist.com/lists/vger.kernel.org/linux-kernel/45/228948.html
made it work. Here's the relevant extra debugging output:

Something other I should try to get this fixed for 2.6.20.2+?
