I'm trying to use a SIIG  UDMA/66 board I pulled from a netbsd/i386
box in my macppc box running 1.6_RC2:

pciide0 at pci0 dev 15 function 0: Triones/Highpoint HPT366 IDE Controller
pciide0: bus-master DMA support present                                   
pciide0: primary channel wired to native-PCI mode
pciide0: using irq 25 for native-PCI interrupt   
wd0 at pciide0 channel 0 drive 0: <IC35L120AVVA07-0>
wd0: drive supports 16-sector PIO transfers, LBA addressing
wd0: 115 GB, 16383 cyl, 16 head, 63 sec, 512 bytes/sect x 241254720 sectors
wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 5 (Ultra/100)   
wd0(pciide0:0:0): using PIO mode 4, Ultra-DMA mode 4 (Ultra/66) (using DMA data transfers)
pciide1 at pci0 dev 15 function 1: Triones/Highpoint HPT366 IDE Controller
pciide1: bus-master DMA support present                                   
pciide1: primary channel wired to native-PCI mode
pciide1: using irq 25 for native-PCI interrupt   

When I try to access it, though, the whole system hangs:

mac# disklabel wd0
pciide0:0:0: lost interrupt
        type: ata tc_bcount: 512 tc_skip: 0
pciide0:0:0: bus-master DMA error: missing interrupt, status=0x21

[dead from here out... network doesn't work, have to crash the
machine ]

Has anybody else had any success with this controller on a mac?

Thanks! (full dmesg follows)
