I am running 14.0-CURRENT using the snapshot from 2021-08-05.  It looks as if setting dumpdev="AUTO" in /etc/rc.conf has no effect on enabling kernel crash dumps. FreeBSD callisto 14.0-CURRENT FreeBSD 14.0-CURRENT #0 main-n248478-f3a3b061216: Thu Aug  5 06:03:20 UTC 2021 root@releng 1.nyi.freebsd.org:/usr/obj/usr/src/arm64.aarch64/sys/GENERIC arm64 I have to manually enable it via dumpon even though it's set to AUTO in  rc.conf
