Hi,
when running 2.4.19-pre7 + ide-2.4.19-p7.all.convert.8.patch i get
a crash on booting while detection of the onboard IDE controller.

00:1f.1 IDE interface: Intel Corp. 82820 820 (Camino 2) Chipset IDE U100 (r=
ev 11) (prog-if 80 [Master])
	Subsystem: Siemens Nixdorf AG: Unknown device 0055
	Flags: bus master, medium devsel, latency 0
	I/O ports at 2400 [size=3D16]

Oops is a "Null pointer dereference at 00000040"
EIP is "ide_dmaproc" + 1e
Call trace "piix_dmaproc" "ide_register_subdriver" "idedisk_init"=20

Decoded by hand. I tried with and with taskfile ..

Config snippet:

CONFIG_BLK_DEV_IDEDISK=3Dy
CONFIG_IDEDISK_MULTI_MODE=3Dy
CONFIG_BLK_DEV_IDECD=3Dm
CONFIG_IDE_TASKFILE_IO=3Dy
CONFIG_BLK_DEV_IDEPCI=3Dy
CONFIG_IDEPCI_SHARE_IRQ=3Dy
CONFIG_BLK_DEV_IDEDMA_PCI=3Dy
CONFIG_IDEDMA_PCI_AUTO=3Dy
CONFIG_BLK_DEV_IDEDMA=3Dy
CONFIG_BLK_DEV_ADMA=3Dy
CONFIG_BLK_DEV_PIIX=3Dy
CONFIG_PIIX_TUNING=3Dy
CONFIG_IDEDMA_AUTO=3Dy
CONFIG_BLK_DEV_IDE_MODES=3Dy

BTW: It seems linux/ide.h misses an include of linux/pci.h
