So, in other words, this problem will likely come and go, due to the Macintosh "inner nature"?? Still, the intermittent behavior is irritating . . . . I believe that in some of my opensuse installs, "we" (at yr suggestion) did lock shim at some point, maybe a year ago?? Not sure if I did that in this install of Leap . . . . Back into the monitoring of it.
