Altered /etc/rc to set -noecc on the SMC11, and ssm(1) and sm(4) to
match, as a result of info from Terabit:  MCT now admits that the
ECC circuits in the SMC11 are buggy and should not be used.  It's a
bit academic here, since some experience with spurious ECCs early
in bringing V7 up led me to fix the driver so it retries before trying
an ECC correction;  this, plus avoiding bad blocks on the disk, has
kept us from ever having a real ECC correction.
