I had a recurrence this morninig, after the update from: FreeBSD g1-55.catwhisker.org 13.0-CURRENT FreeBSD 13.0-CURRENT #120 main-c2= 55894-g8b1839548750-dirty: Tue Jan 12 05:23:50 PST 2021 root@g1-55.catw= hisker.org:/common/S4/obj/usr/src/amd64.amd64/sys/CANARY amd64 1300134 130= 0134 to: FreeBSD g1-55.catwhisker.org 13.0-CURRENT FreeBSD 13.0-CURRENT #121 main-c2= 55921-gec2700e01532-dirty: Wed Jan 13 05:06:22 PST 2021 root@g1-55.catw= hisker.org:/common/S4/obj/usr/src/amd64.amd64/sys/CANARY amd64 1300135 130= 0135 New swcreenshot is in https://www.catwhisker.org/~david/FreeBSD/head/c25592= 1; the previous one is in https://www.catwhisker.org/~david/FreeBSD/head/c2558= 50. They look quite similar to me. After grabbing the screenshot, I rebooted again, but the poweroff just worked normally on re-try. I believe that this is evidence in favor of a "race condition" diagnosis. (In precisely what, I don't know,) Peace, david --=20 David H.
