Problem with HPT370/372 and kernel 2.6.6-1.435.2.3

[Ulisses]

Hi,

	I have a soyo kt400 dragon ultra motherboard with a hpt370/372 raid
controller. The problem is that booting kernel 2.6.6-1.435.2.3 always
ends up with an oops in init_setup_hpt366().

CPU:    0
EIP:    0060:[<0232d6eb>]    Not tainted
EFLAGS: 00010246   (2.6.6-1.435.2.3)

	I can boot with kernel 2.6.5-1.358, but the file /proc/ide/hpt366 shows
garbage in the place of the chipset and the output of the hpt366
initialization code in dmesg is all messed up. I've already booted with
'pci=noacpi', 'noapic' and 'acpi=off', but had the same results with
both kernels. Any ideas?
