There is a company which frequently advertises in _EDN_ magazine which has
a hardware fix for your problem (if indeed it is errata 21).  For example,
see _EDN_, March 15, 1990, p. 217:

  " The FIX-80386 solves the Errata 21 problem that is showing up on
    many PC's.  If your PC locks up when running UNIX or memory
    extenders in MS-DOS you will need this part.  The part is placed
    between the 80386 and its socket... "

The company is Ironwood Electronics, P.O. Box 21151, St. Paul, MN 55121.
Phone number 612-431-7025.

I neither work for Ironwood Electronics, nor have I had occasion to use
their products.  

Hope this helps.
