Hi Andrew,
since 2.6.14-rc4-mm1, my second ata_piix (SATA) controller does not
show up in dmesg, effectively hiding /dev/sdb. 2.6.14-rc2-mm2 and
older (with the same kernel config) were ok, the same for Linus'
kernels: 2.6.14-rc5 without -mm1 has /dev/sdb, too.

This PCI device (on-board on an Asus P4 mainboard) has two SATA
connectors, showing up as ata1/sda and ata2/sdb.

Need more information? I could try to disable a few patches from your
-mm series if you name some.. it's too hard for me to guess which one
could be responsible for the breakage.

Thanks. It'd be useful if you could test just 2.6.14-rc5+git-acpi.patch,
see if that does the same thing.

results:
2.6.14-rc5 + git-acpi.patch + git-acpi-build-fix-2.patch:
ata2 and /dev/sdb are fine.
... + git-libata-all.patch
ata2 and /dev/sdb disappeared.
Tell me when you need further testing.

Thanks for this report. Would it be possible for you to test 2.6.14
(release) and 2.6.14-git1, as additional data points?
Once its out, I might ask you to try 2.6.14-git2 (tonight's upcoming
snapshot) as well.
Regards,
Jeff

I can confirm that. 2.6.14-rc5-mm1 plus your patch fixed my problem,
ata2 and /dev/sdb are available.
