I have VirtualBox VM running 13-CURRENT. In order to switch from

`shutdow -p now` (or select 'ACPI shutdown' in VM menu) fails to power
off. Shutdown itself completes successfully. But power off never
happens and CPU usage keeps high until either closing or resetting VM.

I reinstalled OS by using
FreeBSD-13.0-CURRENT-amd64-20200618-r362292-disc1.iso but the problem
still happens. If I switch back to legacy BIOS then the problem
disappears. And it doesn't happen with either 11.4-RELEASE and
12.1-RELEASE.


Hi,

Same problem using FreeBSD current UEFI guests with bhyve, so it should
happen in any kind of hypervisor.
It is an old regression (in the sense of -current, so older than 6 months).
My idea was to generate very light UEFI VM images (because the snapshot VM
images are BIOS based) and scripting a bisector tool, but I never took the
time to do it.

FWIW, shutdown works for me in VMware Workstation (Windows) and ESXi VMs, UEFI boot.
