More ATAng probing issues

[Steve Ames]

sos,

I had the misfortune of swapping motherboards recently to an Asus
MB with a nVidia controller. Suddenly my drives don't show up on
any recent kernels. They do on a 8/28 kernel. in ata-lowleve.c I
switched the '#if 0' to an '#if 1' and rebooted and now my ad0
(primary controller master drive) is found but my ad1 (primary
controller slave drive) is still missing.

This is what I'm seeing now (with #if 1):

atapci0: <nVidia nForce UDMA100 controller> port 0xb800-0xb80f at device 9.0 on
pci0
ata0: at 0x1f0 irq 14 on atapci0
ata0: [MPSAFE]
ata1: simplex device, DMA on primary only
ata1: at 0x170 irq 15 on atapci0
ata1: [MPSAFE]
ad0: 19541MB <Maxtor 52049H4> [39703/16/63] at ata0-master UDMA100

On the August 28 kernel I have:

atapci0: <nVidia nForce UDMA100 controller> port 0xb800-0xb80f at device 9.0 on pci0
ata0: at 0x1f0 irq 14 on atapci0
ata1: simplex device, DMA on primary only
ata1: at 0x170 irq 15 on atapci0
ad0: 19541MB <Maxtor 52049H4> [39703/16/63] at ata0-master UDMA100
ad1: 39266MB <IC35L040AVER07-0> [79780/16/63] at ata0-slave UDMA100

Thoughts?
