I tried (again) to convert an Intel i815EP-chipset
machine from IDE to libata, but libata still fails
to initialise the CDROM on the machine.
With 2.6.22-rc5, IDE says:
Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
ICH2: IDE controller at PCI slot 0000:00:1f.1

hda: cache flushes supported
hda: hda1 hda2 hda3 hda4 < hda5 hda6 >
Switching to libata (ata_piix) results in:
