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.

I tried the above and the machine just hangs when it comes to: SMP: AP CPU # 1 Launched! :( Manfred ================================== || nu@pozo.com || || Ph. (415) 681-6235 || ==================================
