ide_dmaproc - YaBoot

[Henning Loeser]

Hi,
ok I applied your 2.3.99-pre9 patches to 2.4.0.test1-ac4 sources and at
least the drive is recognized again. dmesg reads:
ide: Assuming 33MHz system bus speed for PIO modes; override with
idebus=xx
AEC6260R: IDE controller on PCI bus 00 dev 68
AEC6260R: chipset revision 1
AEC6260R: not 100% native mode: will probe irqs later
AEC6260R: ROM enabled at 0x80810000
AEC6260: reg49h=0x00 ATA-66 Cable Port0
    ide0: BM-DMA at 0xf2000800-0xf2000807, BIOS settings: hda:pio, hdb:pio
AEC6260: reg49h=0x00 ATA-66 Cable Port1
    ide1: BM-DMA at 0xf2000808-0xf200080f, BIOS settings: hdc:pio, hdd:pio
hda: IBM-DJNA-352030, ATA DISK drive

hda: 39876480 sectors (20417 MB) w/1966KiB Cache, CHS=39560/16/63,
UDMA(66)

but I'm back at the lost interrupt :-(

Partition check:
 hda:hda: lost interrupt

I was wondering after Ben's commend if OF sets the bummaster correct for
the card. Or if I should do something like:
      pci_read_config_word( pdev, PCI_COMMAND, &cmd );
      cmd |= (PCI_COMMAND_MEMORY | PCI_COMMAND_IO);
      pci_write_config_word( pdev, PCI_COMMAND, cmd );

How do I verify the busmaster operation is set up cerrectly ?
