Me too.

166 static void
167 roundrobin(arg)
168         void *arg;
169 {
170 #ifndef SMP
171         struct proc *p = curproc; /* XXX */
172 #endif
173 
174 #ifdef SMP
175         need_resched();
176         forward_roundrobin();
177 #else
178         if (p == PCPU_GET(idleproc) || RTP_PRIO_NEED_RR(p->p_rtprio.type)
    )       
179                 need_resched();
180 #endif
181 
182         callout_reset(&roundrobin_callout, sched_quantum, roundrobin, NUL
    L);
183 }

Should it become:

#ifdef SMP
	mtx_lock_spin(&sched_lock);
	need_resched();
	forward_roundrobin();
	mtx_unlock_spin(&sched_lock);
#else

?

I cannot test it yet, need to reanimate my testbox first.
