2.4.20-pre2-ac4 oops at boot

[Samuel Flory]

  I've been having problem with the ac kernels, and tyan 2720. (Dual
xeon E7500 chipset.) Under 2.4.20-pre2-ac4 it spews a bunch of "Trying
to free nonexistent resource" when initializing the ide interface, and
dies.  Under 2.4.19-ac4 the system netboots, but oops when I attempt to
create a filesystem on a 3ware controller.  Under 2.4.19 the system
boot, and seems to function fine. (No dma support on the ide interface,
however.)

I believe the ide chipset is a ICH3.

ICH3: IDE controller on PCI bus 00 dev f9
PCI: Device 00:1f.1 not available because of resource collisions
ICH3: (ide_setup_pci_device:) Could not enable device.

2.4.20-pre2-ac4:
