Description of Problem:
kernel hangs while detecting disks connected to the Promise 20265 onboard ATA100
controller (board is Asus A7V).

Version-Release number of selected component (if applicable):
kernel-2.4.18-10 (rh-7.3) and kernel-2.4.18-14 (rh-8.0). Older kernels before
2.4.18-10 works good.


How Reproducible:
I'm using these kernel parameters for Promise controller: ide2=0x8800,0x7802.
Kernel changes these parameters to "ide2 at 0x8800-0x8807,0x8402 on irq 10" and
then hangs.


Steps to Reproduce:
1. Connect a harddisk to the ATA100 interface on an Asus A7V motherboard
2. try boot Red Hat Linux 7.3 (kernel-2.4.18-10) or Red Hat Linux 8.0
(kernel-2.4.18-24) from this disk
3. boot is unsuccessful (kernel hangs)

Actual Results:
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
ide2 at 0x8800-0x8807,0x8402 on irq 10

Expected Results:
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
ide2 at 0x8800-0x8807,0x7802 on irq 10

Additional Information:
This simple patch for drivers/ide/ide-pci.c fixes my problem:
