Hi, I release cocalc-docker ([1], [2]) a few days ago with sage-9.4, and had people reporting back "illegal instruction" issues. Sage is built there with SAGE_FAT_BINARY="yes", using this script [3]. One person who reported a problem had a "Dell PowerEdge R710." and I built on an intel Dell PowerEdge R630, for what it is worth. They got the error "An illegal instructor occurred" when computing "5+2" in Sage.
My solution for now is to keep cocalc-docker at sage-9.3 for the time being, and suggest that people build sage from source on their own machine if necessary. I'll let you know if I have any further information, but I just wanted to add this data point.
