I've (finally) gotten my 9600MP up and running.  Thanks to the list
for the help.  Turns out that you really shouldn't accidentally boot
into MacOS and think that SystemDisk fixes are still applied, just as
it says in the install notes.  Go figure.

Any-way, I've moved over a bunch of hardware goodies from my old 7300
into this new beast, and one of them is not working.  I wonder whether
the problem is a toasted disk, or a hardware incompatibility, who
knows.

The controller and disk are identified OK during boot up:

  pciide0 at pci0 dev 14 function 0: Promise Ultra66/ATA Bus Master IDE Accelerator (rev. 0x01)
  pciide0: bus-master DMA support present
  pciide0: primary channel configured to native-PCI mode
  pciide0: using irq 24 for native-PCI interrupt
  wd0 at pciide0 channel 0 drive 0: <WDC WD1600BB-00DAA0>
  wd0: drive supports 16-sector PIO transfers, LBA48 addressing
  wd0: 149 GB, 16383 cyl, 16 head, 63 sec, 512 bytes/sect x 312581808 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)
  pciide0: secondary channel configured to native-PCI mode
  pciide0: disabling secondary channel (no drives)

But when I try to mount a filesystem on the sucker, I get this
horrible sequence of messages:

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

  wd0(pciide0:0:0): using PIO mode 4
  wd0c: DMA error reading fsbn 0 (wd0 bn 0; cn 0 tn 0 sn 0), retrying
  wd0: soft error (corrected)


At that point, the drive appears inoperable, for example one can start
an fsck_ffs on it, but it does not appear to make progress.  Any ideas
about what might be wrong?  I've included a full dmesg output to
provide any necessary context...
