'fraid so.  It's a newer CMD this time, a 223, and trying to use it in
the 4000/500 is just a total no-go, just like with the 220 that I've
got in the KA650-based box that now runs 4.3BSD-Reno.

These controllers work with Ultrix, Reno, 2.11BSD (on PDP-11), VMS,
and, until somewhere in the vicinity of a year ago, NetBSD.  I've
studied the code, looking for changes between code I know worked and
the current state of the drivers, and I can't see anything that should
be able to cause the problems.

NetBSD can't even boot properly from CMD controllers, and the code
involved in *that* is simple enough that I really thought I should be
able to find something, but no...  Can it be a compiler problem?  A
bug related to __volatile__ in the newer GCC, perhaps?  (Just a wild
guess, of course, but it's the time of wild guesses by now.)
