DF-0622: ng_car.ko CANNOT be loaded on this kernel
(struct bintime / getbinuptime / bintime_sub are unported
 FreeBSD-isms; the module is not built, not in the SUBDIR
 Makefile, and not in /boot/kernel/). The bug pattern is
 confirmed in the source (see VERDICT.md). The runtime trigger
 requires a ported ng_car.ko.

See ng_car_trigger.sh for the ngctl sequence that would fire
the panic on a kernel with a working ng_car module.
