I can crash mine with "sysctl -a" as well. I seeded my bhyve with: FreeBSD-15.0-CURRENT-amd64-20231228-fb03f7f8e30d-267242-disc1.iso Rebuilt the kernel (so now at main-n267320-4d08b569a01) and started crunching through poudriere package builds. Sorta stock install of encrypted ZFS. I didn't get it to crash with poudriere (yet). Mine lives in bhyve, so maybe less possible destruction via crashes.
