Summary: ACPI S3 doesn't resume on a MateBook X Pro 2021

Status: New

dmesg.boot
I have a MateBook X Pro 2021 with FreeBSD installed, ACPI S3 doesn't work, when
I run
acpiconf -s 3
the laptop appears to suspend fine, however it will not resume. When I press
the power button to resume the screen stays blank and eventually (after a
couple of minutes) the machine just reboots normally.
After booting back to FreeBSD the last entry in /var/log/messages is the
suspend message.
The laptop suspends and resumes fine on linux.
I tried building a minimal test kernel (MINIMAL config with NO_MODULES and nvme
and nvd devices added). I used FreeBSD 13 stable (commit
bb8e1dfbff30e5df97fa31c88f8218af054fe166). The test kernel had the same issues.
Debugging with:
sysctl debug.bootverbose=1
sysctl debug.acpi.suspend_bounce=1
acpiconf -s 3
worked fine.
I have attached the dmesg.boot, and the /var/log/messages for the
suspend/resume trial (messages.on.suspend) and for when I tried debugging
(messages.on.suspend.test). All theses were taken with the minimal test kernel.
