By rules it's capped to exhausted. I was about to say 'dead' also, but (to my understanding) exhaustion remains active after death. Nonlethal damage and the unconscious status are thematically related, but a different subsystem.
Pathfinder could use some streamlining here, for instance DSA5 has more consistant statuses handling - hence it's way easier to learn.
