Well, the most obvious thing is that they changed the memory allocation
routines around. This is described in section 2.5.3 of the Ultrix 3.0
release notes.
There's no reason to believe that any piece of kernel level object
code will be compatible between releases.
It would really be nice if DEC included a cumulative "incompatibilities
with BSD 4.2/Ultrix 1.0/Ultrix..." section in the release notes. Not
everybody has/keeps the whole set.
