--- Comment #9 from Conrad Meyer <cem@freebsd.org> ---
> Indeed, network domains initialization happens at level SI_SUB_PROTO_DOMAINS, whereas the "random_harvestq" thread is launched later (level SI_SUB_KICK_SCHEDULER). 

Yeah, that's unfortunate.  I don't think domain registration actually needs
random?  But there is a lot of crap in SI_SUB_PROTO_DOMAIN that isn't
DOMAIN_SET().  If you want to pursue it, identifying the stack(s) blocking on
random and moving them after KICK_SCHEDULER would be a valuable contribution to
FreeBSD.
