[CC to linux-smp because of the 'unexpected IO-APIC']

Hi,

Linux detects the two HPT374 controllers, but not the attached drives.

The Mainboard is an EPOX EP-8K5A3+ with 2 VIA vt8235 ide controllers
and 4 Highpoint 374.

I increased the channels: limit for the HPT374 in drivers/ide/pci/hpt366.h
to 4.

So how do I get Linux to detect the ide2,3,4,5 "devices" and the
attached drives?
