But, if I set .config with just AHCI, the kernel will not
load libata at all. dmesg jsut goes from the Uniform CD-ROM
driver revision to usbmon. And I get a kernel panic because
sda doesn't exist.
I've seen some posts about needing to turn AHCI on in the
BIOS. I didn't see anything, so I asked gigabyte:

Question : How do I turn on AHCI for SATA drives? I see no
option in the BIOS. I'd like to use NCQ.

Answer : hello,
By default it's automatically enabled and there are no
options to enable it.
If your hdd supports it there should be a utility to check
whether if it's enabled or not.
Thank you
Any good ideas?

Plain vanilla ICH6 does not support AHCI, but other ICH6 variants such
as ICH6-R do. If your chip does support AHCI, then your BIOS is not
enabling it.
AHCI support is clearly indicated by Region 5, a memory (MMIO) region:

Thanks for the quick response. I've sent another request to
gigabyte for a BIOS update. Fat chance.

Hi Sean,
I also have a 915G based system (AOpen EZ915) and I'm interested to try the
AHCI support. So I checked whether AHCI could be used on my 915G box.
The PCI device ID for my ICH6 is 0x2651.
=> So, no AHCI support. :(
(Only ICH6-R 0x2652 and ICH6-M 0x2653 have AHCI support. Not plain ICH6.
http://download.intel.com/design/chipsets/specupdt/30147411.pdf )
From your previous post
"00:1f.2 IDE interface: Intel Corp. 82801FB/FW (ICH6/ICH6W) "
I guess your box is the same as mine, plain ICH6 without AHCI support.
(You can check the PCI device ID by "lspci -n".)
If so, update BIOS won't help since there is no AHCI support on the hardware.
Albert

Mine is also 0x2651.
But I must be blind, but I don't see any statement that only -R and
-M have AHCI support.

In fact, look at 12.1.15 in
http://developer.intel.com/design/chipsets/datashts/30147302.pdf.
Maybe the driver ( BIOS? ) is not setting the SCRAE bit, whatever the
hxxx that is!
