I am definitely avoiding any of the Cxxxx CPU's now when I am doing hardware selection. If this same bug happened on Intel's server or desktop CPU's, yes it will definitely be a big deal. Just look at AMD's ryzen issue, and that only effected very edge cases.
I wonder if I actually received the same hardware as what I sent in. On one of my other SG-2440 replacements, I got someone else's system w/ a different serial # and config. Granted that system had no functional issues after a config reset. May be it was luck to have gotten someone else's box??
