IDE: pdc202xx_new on Asus A7V333?

[Mårten Berggren]

Hi,

I have been trying to get pdc202xx_new working (in 2.4.27) on my
Asus A7V333 motherboard (with VIA KT333 and a PDC20276). Loading
it as a module with modprobe gives me the following entires in the
syslog:

Sep 18 12:27:25 r2d2 kernel: PDC20276: IDE controller at PCI slot
00:06.0 
Sep 18 12:27:25 r2d2 kernel: PCI: Found IRQ 5 for device 00:06.0 
Sep 18 12:27:25 r2d2 kernel: PCI: Sharing IRQ 5 with 00:09.0 
Sep 18 12:27:25 r2d2 kernel: PCI: Sharing IRQ 5 with 00:10.0 
Sep 18 12:27:25 r2d2 kernel: PDC20276: chipset revision 1 
Sep 18 12:27:25 r2d2 kernel: PDC20276: not 100%% native mode: will probe
irqs later
Sep 18 12:27:25 r2d2 kernel:     ide2: BM-DMA at 0xb000-0xb007, BIOS
settings: hde:pio, hdf:pio
Sep 18 12:27:25 r2d2 kernel:     ide3: BM-DMA at 0xb008-0xb00f, BIOS
settings: hdg:pio, hdh:pio

which gives me the impression that the module has loaded ok, but there
is no matching entries in /proc/ide and pdcraid does not find it.
So is there any way to tell if it is working or not? (Should there
be an entry in /proc/ide?)

If it is not working, can it be because it shares IRQ 5 with my USB
and network card?

(Part of) /proc/pci:

  Bus  0, device   6, function  0:
    RAID bus controller: Promise Technology, Inc. PDC20276 IDE (rev 1).
      IRQ 5.

(Part of) /proc/interrupts:
  5:       2175          XT-PIC  usb-uhci, eth0

Please help; I have spent quite some time on this. I'm not afraid
of printk debugging, but I have no idea how the system should work.

If it's a so-called "raid" version of the PDC, you may need to enable 
CONFIG_PDC202XX_FORCE, as the firmware "hides" the drives.

Good point. I forgot to mention that it is indeed sold as a RAID
system (and it seems to work under XP Pro) and that I have selected
"Ignore BIOS port disabled setting on FastTrak" and "Use PCI DMA by
default when available".

(I also tried to switch PCI-slot for my networking card, but the
effect was that the PDC now shares interrupts with more on-board
USB devices instead of the network card.)
