Problem: RAID auto-detect on my promise PC20378 doesn't seem to work -
but works with other controllers.

First of all - thanks to Mark Hahn for emailing me off list and helping
me out a bit.

I think it's time to bring this back to the list. It seems that, at
least in my configuration, kernel raid auto-detection runs before the
kernel has detected partitions on the SATA Promise driver (note: pata
chain on the SATA controller).

Dmesg showing this below.

I have a RAID-1 array between partitions on a disk on a 82801EB/ER
(ICH5/ICH5R) IDE Controller and my SATA Promise PDC20378 controller.

I have all the required parts BUILT IN to the kernel (kernel config below).

My 82801EB/ER (ICH5/ICH5R) IDE Controller seems to be run by the general
IDE layer - I have no particular drivers enabled.

My Promise PDC20378 is controlled by CONFIG_SCSI_SATA_PROMISE with the
libata1.patch from Jeff in order to support the PATA part of the
controller. Again, built in, NOT a module.

RAID1 support is also built in.

What happens is:

Recongize ICH5/ICH5R
Initialize partitions on ICH5/ICH5R
Recognize PDC20378
Raid auto-detect
Recognize partitions on PDC20378

Kernel is a kernel.org 2.6.15 with SMP support and Jeff's libata1.patch.

Any help would be greatly appreciated. I'm happy to try patches, provide
any details I've left out, etc.
