>Description:
My PCI cmdide0: Silicon Image 0680 based card appears to work as advertised in an UltraSPARC 30 system, but is completely ignored by an UltraSPARC 10 system.  Could be due to the built-in IDE bus in the UltraSPARC 10.

relevant dmesg from UltraSPARC 30:
cmdide0 at pci0 dev 2 function 0
cmdide0: Silicon Image 0680 (rev. 0x02)
cmdide0: bus-master DMA support present
cmdide0: primary channel configured to native-PCI mode
OF_mapintr failed
cmdide0: using ivec 7d0 for native-PCI interrupt
atabus0 at cmdide0 channel 0
cmdide0: secondary channel configured to native-PCI mode
atabus1 at cmdide0 channel 1
[...]
wd0 at atabus0 drive 0: <WDC AC33100H>
wd0: drive supports 16-sector PIO transfers, LBA addressing
wd0: 3020 MB, 6136 cyl, 16 head, 63 sec, 512 bytes/sect x 6185088 sectors
wd0: drive supports PIO mode 4, DMA mode 2
wd0(cmdide0:0:0): using PIO mode 4, DMA mode 2 (using DMA data transfers)

Relevant dmesg from UltraSPARC 10 (i.e. built-in IDE bus):
cmdide0 at pci1 dev 3 function 0
cmdide0: CMD Technology PCI0646 (rev. 0x03)
cmdide0: bus-master DMA support present
cmdide0: primary channel configured to native-PCI mode
cmdide0: using ivec 1820 for native-PCI interrupt
atabus0 at cmdide0 channel 0
cmdide0: secondary channel configured to native-PCI mode
atabus1 at cmdide0 channel 1

This might be a hardware issue as well, since an Open Firmware "show-devs" command gives different results.

From UltraSPARC 30:
/pci@1f,4000/raid@2

From UltraSPARC 10:
no equivalent device
