See Bugzilla 219399 and 221029 : https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219399 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D221029 I'm not sure how much stable/11 and the like have been tracking things that were done in head (12) during this. My use has only been via versions of head. My 1800X use was basically after head was updated to deal with what 219399 eventually was isolated to. (221029 is from splitting off problems that were not originally known to be separate.) While I had problems for 1800X that are what the 221029 bugzilla above is about, I've not had such with a 1950X in the same sorts of contexts as I had been using the 1800X. But this was under Hyper-V for both processor variants (with matching boards). I've only tried the 1950X with a native FreeBSD boot once (a fair time ago). It showed a lockup problem fairly quickly (power switch/plug time). I've never seen such (or anything analogous) under Hyper-V with extensive use. It does not look like I'll be investigating native FreeBSD on the 1950X anytime soon. (I no longer have access to the 1800X.) =3D=3D=3D Mark Millard marklmi26-fbsd at yahoo.com ( markmi at dsl-only.net is going away in 2018-Feb, late)=
