Well, it was actually disconnected by the 221869 commit, before being removed via 221870. Both were on 20150514. So you need to go back before 221869. I just put some notes into the wiki page: https://wiki.freebsd.org/FreeBSD/sun4v Personally I would start with 221124 which involved the last previous commit to GENERIC on 20110427: https://svnweb.freebsd.org/base/head/sys/sun4v/conf/GENERIC?r1=220982&r2=221124&pathrev=221124 It's not that much farther back, and maybe one could speculate that that change had been build-tested. Perhaps not, but from there you could start walking back through the changes in sys/sun4v to find the last buildable point. Having looked at this, I now think it's a harder problem than I first suspected. It would be fun to work on, though. mcl
