You can't compile SATA as a module if you're going to be booting from a SATA drive. Compile them into your kernel and try again. If that doesn't solve your problem, search the forums. There's tons of people (myself included) who had this exact problem.....

Your grub config is fine. The only thing you need to add is 'udev' to the end of the kernel line, but that won't solve the problems that you're having right now.

1) Are you sure that you're using the right SATA drivers? The ones under the IDE section are deprecated, you must use the ones in the SCSI section.

2) Are you sure you are using the right SATA drivers for your motherboard? Check the output of 'lspci' and compare that to the choices in the kernel config. Post the output here if you're not sure.

3) Are you sure that SCSI support itself is built into the kernel? At a very minimum, you need SCSI support, and support for SCSI drives. It's late here, so I could be missing something. When in doubt, include it.

Did you do as I said and search the forums? There's tons of people a lot smarter and more experienced than I am that have already answered this question.

I feel your pain. I was about to toss the Gentoo install cd out the window after spending hours trying to get my SATA drivers to work.

I had the identical problem when I first installed using genkernel, but it magically disappeared when i entirely removed the "ramdisk=8192" arugment.

"invalid" is not "could not find", so it's probably not a problem with your ide controller modules or anything.

It can find the device, it just can't mount it...

Have you got reiserfs compiled into your kernel (not a module)?

Have you tried running fsck.reiserfs /dev/sda3? maybe your filesystem is corupted, although I can hardly believe it would be corupted already

did all by handbook .. the filesystems were ok .. the drivers were as modules not built-in that's why it didn't work .. heh
