That is true. Still there are close analogies. Not sure but
that timeout could be an effect of BIOS (possibly indirectly).
Or maybe this is another surprise from libata.

So you are using ata_piix. Does not change the general issue.

I think that you are right. A picture you attached may suggest
initrd, as this is only a small fragment, but dmesg you posted from
2.6.25-0.90.rc3.git5.fc9 shows that
.....
ata1: SATA link down (SStatus 221 SControl 300) <----!!!
ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
ata2.00: ATAPI: PIONEER DVD-RW DVR-212, 1.21, max UDMA/66
ata2.00: configured for UDMA/66
scsi 1:0:0:0: CD-ROM PIONEER DVD-RW DVR-212 1.21 PQ: 0 ANSI: 5
.....
So your CD-ROM is identified but you have no disk. If you are not
booting from somewhere else into a ramdisk it is hard to expect for
this to work.
"Lost disks" is what basically happened in bugzilla 436591.
I got around, but not without other side-effects, by replacing
BIOS; but I mention in comments other reports of the same sort.
