(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.)
