As far as I can tell, FreeBSD doesn't support suspend to disk on all
architectures. On amd64 the necessary infrastructure doesn't exist, and on
i386 FPU state is lost, there is no multiprocessor support and some MSRs are
not restored [1].


And even suspend to RAM doesn't work on every machine [2].
