I do not have any idea right now. I recall having had some difficulties some
time ago with ata_piix when piix itself was not disabled, but those were in
the early libata times. I *believe* it's OK now but you might want to check.
Also, is your CDROM driver parallel ATA or SATA ? It is not clear to me from
your logs. Because if it is ATA, you should need to run with piix enabled just
for it, and, if my memory serves me correctly, to start piix before ata_piix.
I have CCed Jeff who's the libata author, just in case he has an opinion or
even a good advice on the subject. But please don't harrass him since he told
us a long time ago that he did not want to spend much time on 2.4's libata.
BTW, what motherboard is it ? And provided that the CDROM drive finally works,
or that we find a valid reason for it not to work, are you implicitly asking
for mainline inclusion of your patch (or a fixed one) or is it here just for
explanation purposes ?
