Hmm, this is strange. I build the same kernel with:
makeoptions	DEBUG=-g
options         DDB                     #Enable the kernel debugger
options         INVARIANTS              #Enable calls of extra sanity
checking
options         INVARIANT_SUPPORT       #Extra sanity checks of internal
structures, required by INVARIANTS
options         WITNESS                 #Enable checks to detect
deadlocks and cycles
options         MAC
options         MAC_DEBUG

Now it doesn't hang and there is nothing in the logs.

Btw here is some info:
security.mac.debug.label_fallback: 0
security.mac.debug.counters.mbufs: 0
security.mac.debug.counters.creds: 17
security.mac.debug.counters.ifnets: 3
security.mac.debug.counters.ipqs: 0
security.mac.debug.counters.bpfdescs: 0
security.mac.debug.counters.sockets: 7
security.mac.debug.counters.pipes: 2
security.mac.debug.counters.procs: 63
security.mac.debug.counters.mounts: 6
security.mac.debug.counters.temp: 0
security.mac.debug.counters.vnodes: 429
security.mac.debug.counters.devfsdirents: 96

Again I am not running anything but the base system and ssh.
