I attempted to jump from head -r334014 to -r339076
on a threadripper 1950X board and the native
FreeBSD boot failed very early. (Hyper-V use of
the same media did not have this issue.)
But copying over an older /boot/loader from another
storage device with a FreeBSD head version that has
not been updated yet got past the problem being
reported here. (For other reasons, the kernel has
been moved back to -r338804 --and with that,
and the older /boot/loader, the 1950X native-boots
FreeBSD all the way just fine.)
For the BTX failure the display ends up with
(hand transcribed, ". . ." for an omission):
BTX loader 1.00 BTX version is 1.02
Console: internal video/keyboard
BIOS drive C: is disk0
. . .
BIOS drive P: is disk13

The board is a GIGABYTE X399 AORUS Gaming 7 (rev 1.0).
It has 96 GiBytes of ECC RAM, just 6 DIMMs installed.
