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.
