Intel ICH4 ide not working for 2.4.19 and 2.4.20

I have a machine with a Gigabyte 8IEX motherboard. This MB uses an Intel 845E
chipset with an Intel ICH4. I'm using a 2.4 GHz P4 with it, and 1 GByte of

I have been using RedHat kernels, initially 2.4.18-14 from RedHat 8.0, which
works o.k.

Then I tried some kernels from rawhide, first 2.4.19-0.pp18, then
2.4.19.pp.20, and finally 2.4.20-0.pp.3. These all failed to identify
anything attached to the ide ports.

Finally, I grabbed a copy of the original 2.4.20 kernel sources, applied the
2.4.20-ac2 patches, and compiled these with a similar config to that used by
the RedHat kernels. This failed in a similar way to the redhat kernels.

I don't have another machine hooked up to the serial port at the moment, but a
hand copied version of the on-screen messages leading up the point of failure

Uniform Multi-Platform E-IDE driver Revision: 7.00beta-2.4
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
ICH4: IDE controller at PCI slot 00:1f.1
PCI: Found IRQ 5 for device 00:1f.1
ICH4: chipset revision 1
ICH4: not 100% native mode: will probe irqs later
    ide0: BM-DMA at 0xcc00-0xcc07, BIOS settings: hda:DMA, hdb:DMA
    ide1: BM-DMA at 0xcc08-0xcc0f, BIOS settings: hdc:DMA, hdd:DMA

There is a delay of a second or two here while the ide devices are failed to
be detected. The boot process then continues until it fails because it
cannot open the root device.

I've looked through the archives and there doesn't appear to be anyone else
with this particular problem. Does anyone have an idea about what I should
do to fix my problem?
