  The amiga/dev/sd.c (and st.c) is no longer being used.

  Hmmm.  I'm not sure where that routine is supposed to be, but it
certain shouldn't be in the driver file that may not be included.

  Maybe you are the first on to test the A3000 driver code?  I don't
know if Chris Hopps had anyone try out the A3000 or A2091 driver.
Neither he nor I have an A3000 to test A3000-specific things on.

  Oh oh - I found what may be the problem:  a3000dmaintr() calls
sbicintr, but passes the controller number instead of the sbic_softc
pointer.  Try changing "sbicintr(i)" to "sbicintr(dev)".  The A2091
driver has the same bug (atzsc.c).

  The panic is probably caused by a bug when a keyboard interrupt
is generated before the console device has been opened.

  I doubt it.

  SCSI2 is the value the drive reports in the inquiry data.  It has 
nothing to do with the host adapter.
