    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.

          I/O at 0xa000 [0xa0ff].
          Non-prefetchable 32 bit memory at 0xd3800000 [0xd3800fff].

    (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.

    Regards
