Bug ID: 247474
Summary: `shutdown -p now` fails to power off with VirtualBox
UEFI boot
Product: Base System
Version: CURRENT
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: b...@freebsd.org
Reporter: y...@utahime.org
I have VirtualBox VM running 13-CURRENT. Environments are
Host: 64bit Windows 10 ver. 1909
VirtualBox: 6.1.10
VM: 4CPU, 8GB Memory, 100GB Disk, Audio disabled. Bridged NIC
In order to switch from legacy BIOS to UEFI I enabled UEFI on VM settings and
reinstalled OS by using FreeBSD-13.0-CURRENT-amd64-20200611-r362037-disc1.iso.
After that `shutdown -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. If I switch back
to legacy BIOS and reinstall OS then the problem disappears. And it doesn't
happen with either 11.4-RELEASE or 12.1-RELEASE.
I tried bisect and found this problem happens with base r342108 and
after. Commit message of base r342108 says as following.
