My addition is going to lack even worse, I have been seeing very long periods of lag, on this 40 second order, when a bhyve instance is started. The interactive response for this time is 0, not even ^t produces any output. The prompt comes back almost immediatly after typing the bhyve command, but that prompt is dead for a very long time. I am running 12.0-RELEASE, and see this issue on multiple machines. > > Information, including verbose dmesg.boot copies and a log of uname > outputs, may be found from the page at > . > > Here's a list of the uname outputs for head over the last several days: > > FreeBSD 13.0-CURRENT #245 r343551M/343551: Tue Jan 29 03:54:46 PST 2019 root@g1-49.catwhisker.org:/common/S4/obj/usr/src/amd64.amd64/sys/CANARY amd64 1300010 > FreeBSD 13.0-CURRENT #246 r343572M/343572: Wed Jan 30 05:14:44 PST 2019 root@g1-49.catwhisker.org:/common/S4/obj/usr/src/amd64.amd64/sys/CANARY amd64 1300010 > FreeBSD 13.0-CURRENT #247 r343604M/343604: Thu Jan 31 03:53:37 PST 2019 root@g1-49.catwhisker.org:/common/S4/obj/usr/src/amd64.amd64/sys/CANARY amd64 1300010 > FreeBSD 13.0-CURRENT #248 r343646M/343658: Fri Feb 1 04:05:45 PST 2019 root@g1-49.catwhisker.org:/common/S4/obj/usr/src/amd64.amd64/sys/CANARY amd64 1300010 > FreeBSD 13.0-CURRENT #249 r343678M/343678: Sat Feb 2 03:55:23 PST 2019 root@g1-49.catwhisker.org:/common/S4/obj/usr/src/amd64.amd64/sys/CANARY amd64 1300010 > FreeBSD 13.0-CURRENT #250 r343707M/343711: Sun Feb 3 04:06:08 PST 2019 root@g1-49.catwhisker.org:/common/S4/obj/usr/src/amd64.amd64/sys/CANARY amd64 1300010 > FreeBSD 13.0-CURRENT #251 r343732M/343741: Mon Feb 4 04:24:07 PST 2019 root@g1-49.catwhisker.org:/common/S4/obj/usr/src/amd64.amd64/sys/CANARY amd64 1300010 > FreeBSD 13.0-CURRENT #252 r343770M/343771: Tue Feb 5 04:27:38 PST 2019 root@g1-49.catwhisker.org:/common/S4/obj/usr/src/amd64.amd64/sys/CANARY amd64 1300010 > FreeBSD 13.0-CURRENT #253 r343828M/343834: Wed Feb 6 03:59:36 PST 2019 root@g1-49.catwhisker.org:/common/S4/obj/usr/src/amd64.amd64/sys/CANARY amd64 1300010 > FreeBSD 13.0-CURRENT #254 r343867M/343867: Thu Feb 7 04:52:38 PST 2019 root@g1-49.catwhisker.org:/common/S4/obj/usr/src/amd64.amd64/sys/CANARY amd64 1300010 > > Peace, > david > -- > David H.
