I have been unable to boot FreeBSD 13.0-RELEASE installation media on a Lenovo
ThinkCentre 91p.  The boot process displays EFI framebuffer information and
then hangs.  I have tried this with standard boot, "safe mode" boot, boot to
single user, and it always hangs in the same place.  The -v option doesn't
produce any additional information. I have tried this with the memstick image
(https://download.freebsd.org/releases/amd64/amd64/ISO-IMAGES/13.0/FreeBSD-13.0-RELEASE-amd64-memstick.img)
and the DVD image
(https://download.freebsd.org/releases/amd64/amd64/ISO-IMAGES/13.0/FreeBSD-13.0-RELEASE-amd64-dvd1.iso)
with the same results.

This is not a general ThinkCentre issue.  The same media boot fine on a
ThinkCentre M93p.  It is also not an obvious hardware defect; disks with older
versions of FreeBSD also work fine.
