The problem on FreeBSD CURRENT at least is caused by the bhyve UEFI 
firmware that's running: I've committed a fix upstream to fix it 
(https://github.com/tianocore/edk2/commit/f159102a130fac9b416418eb9b6fa35b63426ca5), 
but still need to get CSM support working again before we can switch 
everyone over from the UDK2014.SP1 build to the newer code.
