Wierd ATA-Detection on MIATA (Beta4 and 5.2.1)

[Lukas Kaminski]

Hi,

on my Miata ( PWS 500au ) the cypress ide controller is somehow detected
twice, or not correctly.

(Generic-kernel 5.2.1)

... isa0: <ISA bus> on isab0
atapci0: <Cypress 82C693 ATA controller> port
0x90a0-0x90af,0x3f4-0x3f7,0x1f0-0x1f7 irq 254 at device 7.1 on pci0
ata0: at 0x1f0 irq 14 on atapci0
ata0: interrupting at ISA irq 14
ata0: [MPSAFE]
ata1: at 0x170 irq 15 on atapci0
ata1: interrupting at ISA irq 15
ata1: [MPSAFE]
atapci1: <GENERIC ATA controller> port 0x374-0x377,0x170-0x177 mem
0x81170000-0x8117ffff at device 7.2 on pci0
atapci1: unable to map interrupt
ohci0: <OHCI (generic) USB con ...

and then

GEOM: create disk ad0 dp=0xfffffc00173bc4a0

acd0: DVDR <HL-DT-ST DVDRAM GSA-4040B> at ata1-master BIOSPIO
Waiting 15 seconds for SCSI devices to settle
...

This happens on FreeBSD 5.2.1 (generic kernel) and on Beta 4.
Is there a way to disable the detection of a "GENERIC ATA controller"?
The drive is working, but only in PIO mode. (it supports DMA).
If DMA is enabled, the system locks up if the hd is accessed.


I've managed to upgrade to Beta 4 (only a custom kernel works, generic
won't boot), but the problem still persists.
