Both controllers were never enabled at the same time. Since I only got
one IDE drive in the system and that one's connected to the Highpoint
controller. I always disabled the PIIX4 IDE controller.

And so does the Highpoint controller. You can hook up to eight IDE
drives onto an Abit BP6 mainboard.

On the UDMA33 I can enable/disable individual channels, on the Highpoint
everything is "automatic" and the Highpoint BIOS autodetects the drives
on it's controller. I believe in later revisions of the BP6 BIOS you can
enter a separate menu to tune the Highpoint controller, but I never did
a bios upgrade.

They weren't.

No. I've attached two dmesg's (from /var/log/messages). One including
the ata driver in the kernel and with the Highpoint IDE controller
enabled and the other with all IDE disabled (the current configuration).
Please pay no attention to the unconfigured USB hardware about which the
kernel complains. I didn't get around to configuring that yet. The USB
has it's irq disabled in the BIOS. I don't think it's causing the stray
irq7's however, because it's configuration hasn't changed between the
dmesgs and the stray irq7's went away anyway. Also, no usb devices are
attached.
Regards,
Dave.
