I've been working on a problem with Promise 20269 PATA adapter under LibATA
that if I attach a CDROM drive, I can not see the drive. The message log
reports that the driver sees the device, but when I'm fully booted, there's
no device available. If I attach it to the motherboard IDE bus, I can
access it just fine. I've attached a copy of the boot log and you'll see
the motherboard CD/DVD and the one attached to the Promise. I suspect the
PDC driver isn't handling the CDrom. I'm currently running 2.6.15.
Best wishes,

Sounds like your problem there.. need to enable ATAPI in your
libata/PATA kernel configuration?

Please don't drop cc's etc. Just use reply-to-all.
For John: this means that you need to load libata with this option:
atapi_enabled=1
So if you build it into the kernel image, add this to the boot option:
libata.atapi_enabled=1
or if you load it as a module, just add: atapi_enabled=1
or you can edit the source file and change the variable to 1,
but that's the least preferable way IMO.
