--- Comment #1 from Aeryn <[email protected]> ---
Also, this problem occurs on the ThinkPad T480 with libreboot installed. In
addition, another FreeBSD user I've encountered had the same issue on his
ThinkPad T420 with libreboot installed.

The problem occurs regardless of the payload, graphics initialization metho=
d,
and the presence or absence of VBIOS.
