2.6.12-rc5-git6 mis-counted ide interfaces

Hi,
  I get the following when I boot my PIIX computer (Asus P4C800E-Deluxe):


Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2

I believe these two lines from .config are related:

Yes, I do, I was just fooled why I see twice probe for ide1. So you say the "extra"
probe for ide1 is because of CONFIG_IDE_GENERIC=y?

The next ide port are two SATA port and two SATA-RAID ports, btw.

It works fine, just the *extra* "Probing IDE interface ide1..." line made me
worry about.

                         ^^^^ Here's ide0

Does the kernel boot and run OK, or does something actually go wrong?

Why?

I fail to see the problem -- the kernel probes ide0 once, and ide1 once.
I'd assume that that is what's supposed to happen ..?

I't be more worried if it decided to check ide0 again.
