hangup screen

FreeBSD 11.0-RELEASE-p2, generic kernel, Supermicro server (X9SCL-F MB) with a
recent BIOS (v2.2). See the attached screen for details. 100% reproducible.
Boots fine from GPT/MBR. Isn't affected by the hw.vga.textmode.

Furthermore, I cannot make it boot automatically, see my message in the stable@
for details -
https://lists.freebsd.org/pipermail/freebsd-stable/2016-August/085280.html:

"Recently I've installed FreeBSD 10.3 as an experiment to get the 
UEFI-enabled system, on one of mine Supermicro servers. The installer 
worked just fine, but after insttallation I got myself a problem: it 
cannot boot. If I select to boot the old way, froma disk, BIOS says 
there's no valid boot device, and I guess i'ts as intended. When I 
select to boot to the UEFI shell, I got a listing of valid boot deviced 
identificators, and then an error:

===Cut===

'f??('is not recognized as an internal or external command, operable 
program or batch file

Exit status code: Invalid parameter

===Cut===

and the booting process bails to the shell itself.

When I enter

===Cut===

fs0:

EFI\BOOT\BOOTX64.EFI

===Cut===

FreeBSD boots just fine, but I would rather see it boots automatically."

as the final attempt to resolve this I've upgraded the installed system to
11.0-p2 (nothing changed) and upgraded it's BIOS from 2.0b to 2.2 (got this
hangup problem). I'm not entirely sure who's problem is that, but FreeBSD
totally lacks any documentation about installing UEFI loaders, so at least this
is worth attention. Still both problems can be caused by the FreeBSD UEFI
support.

Workaround: change to the legacy GPT/MBR bootstrap scheme.
