Check the list archives and the linux-mac68k@mac-linux-m68k.org mailing
list for a list of the LC040 chips that have a bad mask revision.  There
were some LC040 chips that were bad and will not work properly even with
an FPU emulator.  Apple seems to have used a large number of these chips
in Macintoshes.  What you are experiencing are the exact symptoms of an
LC040 with a bad mask revision.  The solution is to replace with a 68040
or an LC040 with a known good mask revision.
