--- Comment #20 from Graham Perrin <grahamperrin@freebsd.org> ---
With bug 261773 fixed in February 2022, I wonder whether what remains here =
is a
mixture of reports =E2=80=A6


(In reply to Peter Much from comment #19)

> =E2=80=A6 no further interaction is possible,=20

If things seem stuck at ttyv0, then does e.g. Alt-F3 followed by Alt-F2 have
any effect?


> hard poweroff necessary, =E2=80=A6

Try this in your /etc/sysctl.conf

hw.acpi.power_button_state=3D"S5"

=E2=80=93 then restart the computer, and next time things seem stuck: try a=
 _short_
press on the power button (not so hard).
