  Sorry for the incredible delay in answering.  Things have really been
piling up here.

  The generic kernel won't recognize your DH11's because it wasn't
compiler with DH11 support.  The generic kernels are only intended to be
used long enough for you to configure and compile your own kernel.

  The hanging that you describe sounds like you haven't defined the
ROOTDEV, PIPEDEV, SWAPDEV, and/or NSWAP correctly.  Check those
definitions carefully in your configuration file.  The generic kernel's
values for these are edited in by the script /GENALLSYS.  When you just
compile the GENERIC kernel and try to run it you get some random set of
values for these.
