Lousy OCR of the picture:
...
nic: nutex mrsas_sin_lock not ouned at /usr/src/sys/kern/kern_nutex.c:284

This looks like a fallout from r342064.
cm_callout is initialized like this:
	callout_init_mtx(&cmd->cm_callout, &sc->sim_lock, 0);
but in mrsas_complete_cmd() it's stopped without holding the lock.
