These are very similar to the messages I got from an 53c810a when I
tried to upgrade from 1.3.3 to 1.4.1 in an i386:

	CACHE TEST FAILURE: host wrote 1, ncr read 3827772
	CACHE TEST FAILURE: ncr wrote 2, host read 0
	CACHE INCORRECTLY CONFIGURED

That was on an overclock amd586 and it was suggested that I drop the
clock rate, but I never got to try that.  Is there any analogy to
overclocking in the CATS world?
