Yes, I believe the issue is caused by the patch, which is supposed to PR 211746:
Sorry for causing the issue to you, but I suspect the patch reveals a bug in
host's firmware: the memory map reported by the host's firmware may be
Can you please try the patch to dump the memory map?

Note: there is a 10-second pause every time 5 lines are printed. This is to make

About how to apply the patch and build/install it:
'wget' the above patch, and 'cd' into your FREEBSD_SOURCE_ROOT/sys/boot/ and run
"patch -p3 < the_patch_name". If you have run 'make buildworld", just run
'make' in the
sys/boot/ directory and copy the new loader.efi into the boot folder, e.g. in
my side, I
cp -iv /usr/obj/root/bsd.git/sys/boot/efi/loader/loader.efi /boot/loader.efi
