As long as you get this error you miss HDD controller support.

Edit: Boot up with some good LiveCD, run lspci -v, write down all drivers in use, enable the very same drivers in your kernel, doesn't sound impossible, does it?

Edit 2: My first kernel build took 14 hrs, today's machines are not that slow, it takes less than 4 min now. Meaning start with lean kernel, disable all bells and whistles, ACPI and APM, things like that. And if you need help describe exactly to what point it boots, plus error messages.

Checklist:
1. HDD controller
2. MS partition table support
3. Root filesystem

This would suffice for IDE drives using PATA drivers.

With libata you need also SCSI and SCSI disk support.

These is the drivers I couldnt find in the kernel, perhaps someone could identify some of the drivers for me?
However, I suspect that the IDE controller is "Intel PIIXn" (according to gentoo forums) but I'm not sure. Also the PCI Bridge (i guess) is CONFIG_PCI, but also here, not sure (do you have to select a specific PCI bridge btw?) but the rest I have no clue about.
Also, I added support for all "normal" fs available (except like minix and the misc ones), but still not able to read the drive.
Any new suggestions? :S

That's funny, my lspci output is different:
Code:
03:00.0 SCSI storage controller: Adaptec AHA-2940U/UW / AHA-39xx / AIC-7895 (rev 03)
        Subsystem: Adaptec AHA-2940U/2940UW Dual

        Expansion ROM at feb00000 [disabled] [size=64K]
        Kernel driver in use: aic7xxx
See that kernel driver line?
Try with lspci -vv or -vvv.
Intel Corporation 82801AA IDE Controller is your controller indeed, PIIX driver is probably the correct one. What's the PCI-ID of it? Where your boot stops now? Still the same error?

Yeah I see that now. According to gentoo portage I'm running 2.2.10.
However I cant find any modules/drivers in the very verbose version either. Maybe you got another mod of pciutils? Or maybe it just dont work, cause I tried -k aswell without result, just acts as a normal lspci. :s

This is the ouput i get from lspci -vvv:

This is the PCI_ID, right?

The boots stops at the very same place as before. Still same error. :/

OK, did you run lspci with -nv option as I suggested and checked it at http://kmuto.jp/debian/hcl/

Ok, now I've checked against the database (and finally i did find the 82801aa support unde I2C! ) but I still get the same error msg when I'm trying to boot.
I have to say that all the drivers wasnt name exact as they where in the database in the kernel but I added those that looked logic for the specific device, so I dont think I screw up there.

Might be wrong in my grub.conf anyway? :S

I2C?
Database tells 8086:2411 works with PIIX. You built in PIIX and still get "unknown-block(0,0)" message? grub.conf you posted earlier is correct.

You have enabled both, not a good idea. Don't know, your HDD may be recognized as sda as a result, meaning the line root=/dev/hda3 in the grub.conf becomes wrong.

Edit: Remember, if you choose to use libata then you must enable SCSI and SCSI disk.

Finally! Thx alot
Removed the ATA_PIIX and it works fine now=)
Or well, not fine cause there was some other problem with the filesystem but atleast it boots now. The other is a different problem and I wont bother anymore. Once again, thx alot.
