boot_verbose=yes in loader.conf.

debug.bootverbose can be set at runtime with sysctl (I should make that a
tuneable as well, but it isn't today). I should also add it to
loader.conf(5). It's way more important than verbose_loading which is
limited to being verbose around loading klds.

It's obscurely documented in loader.efi(8):
           boot flag        loader variable        Kernel RB_ flag
           -a               boot_askme             RB_ASKNAME
           -c               boot_cdrom             RB_CDROM
           -d               boot_ddb               RB_KDB
           -r               boot_dfltroot          RB_DFLTROOT
           -D               boot_multiple          RB_MULTIPLE
           -m               boot_mute              RB_MUTE
           -g               boot_gdb               RB_GDB
           -h               boot_serial            RB_SERIAL
           -p               boot_pause             RB_PAUSE
           -P               boot_probe             RB_PROBE
           -s               boot_single            RB_SINGLE
           -v               boot_verbose           RB_VERBOSE
but it also works for BIOS booting. The loader man pages are a mess. A lot
of that is my fault. You can set any of the above to "yes" or "no".
