I had an article on this somewhere, but I don't know where I've put it.
I'll look around tonight.  Anyway, from what I remember, it only affected
certain CPU modules with fairly large amounts of cache.  I never saw anybody
from any of the SPARC related mailing lists that I'm on mention it, but I'm
missing a couple of the big ones.  I know of 1 customer who was having that
problem on an E10000 (and BOY were they pissed).  I seem to recall that Sun
has identified the affected CPUs, and the cause of the problem, so it should
be healthy/safe.  At least as much so as any computer hardware is.  :-)  I'm
sure others will know something about this as well.  Later,
