Problem Description:

It has been reported that large applications that run fine under SunOS
4.1.1 on the SS-1  / SS-1+ and other SUN4 machines, crash the SS-2 machine
running SunOS 4.1.1. 

The symptoms are:

	screen goes black
	cpu light goes out
	L1-A does not work
	user typically has to power the machine off and restart machine again

INSTALL:
   as root install the  sun4c patches as follows:

      #  mv /sys/sun4c/OBJ/machdep.o /sys/sun4c/OBJ/machdep.o.orig
      #  mv /sys/sun4c/OBJ/locore.o /sys/sun4c/OBJ/locore.o.orig
      #  cp sun4c/machdep.o /sys/sun4c/OBJ/machdep.o
      #  cp sun4c/locore.o /sys/sun4c/OBJ/locore.o
      #  chmod 444 /sys/sun4c/OBJ/machdep.o
      #  chmod 444 /sys/sun4c/OBJ/locore.o


Then a new kernel will need to be made and installed.  Please refer to the
System and Network Administration manual for installing a custom kernel
