RAID card shows SCSI and unwanted IDE devices

[Keith Goettert]

I am using a Hipoint IDE RAID card.  The driver that Hipoint has created makes the card appear to be a scsi device.  This all works fine and I can access the array as though it was a single SCSI drive.  Unfortunately, the kernel also detects the hpt370 ide controller chips and attempts to configure an hd"x" device for each drive in the array.  This fails during boot with "interrupt lost" errors and greatly lengthens the boot cycle.  The system runs fine except for disk utilities like Mondo that attempt to catalog the phantom drives and end up locking up the system. How can I tell the kernel not to detect these ide devices but still detect the other valid ide devices (like the CDROM and some non-RAID drives)? Boot messages follow... . . .
