Hello.
I didn't get a chance to try that release, but since then many of the
libata patches have been merged into Linus's post-2.6.19 tree, which
I'm now running. The CD-ROM drive is still not being found,
unfortunately. Trimmed 'dmesg' output below:

Although the CD-ROM wasn't found, the bootup was speedier than it had
been with the libata code from the 2.6.19-pre releases. I notice that
the 'revalidation failed' value is different that what I had been
seeing, also. Here is trimmed 'dmesg' output from when I first tried out
the new libata code:

In better news, I'm running Linus' current tree on a SMP PIII machine
which also uses the piix motherboard. This machine previous would
also not find the CD-ROM and had long delays probing the disks during
bootup. I'm pleased to report both problems are solved!
Please let me know what other info I can pass along to help identify
the problem, and I'll be glad to test patches.
My thanks to everyone working on Linux and the new libata code.
