            Bug ID: 277450
           Summary: "poweroff" does not power off the system when EFI is
                    used
           Product: Base System
           Version: 14.0-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: thomas.dreibholz@gmail.com

"poweroff" does not automatically power off the system when EFI is used.
Instead, the machine just halts buts remains running. I tested this with
VirtualBox EFI guests (FreeBSD 14.0-RELEASE) using ICH9 chipset; the issue =
is
reproducible and occurs always.

https://forums.freebsd.org/threads/efi-virtualbox-computer-non-stop-after-s=
uccessful-shutdown-of-freebsd.84856/
suggests to change sysctl hw.efi.poweroff=3D0, which is 1 by default. This =
indeed
fixes the issue.
