>Description:

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: bus-master DMA error: missing interrupt, status=0x21               
                                                                                
[dead from here out... network doesn't work, have to crash the                  
machine ]                                                                       

>How-To-Repeat:
	try to use a drive connected to a HPT controller on a macppc
machine.
