为什么在k210上使用多核smp总是会卡死

#ifdef RT_USING_SMP
rt_base_t rt_hw_local_irq_disable();
void rt_hw_local_irq_enable(rt_base_t level);
#define rt_hw_interrupt_disable rt_cpus_lock
#define rt_hw_interrupt_enable rt_cpus_unlock
#else
rt_base_t rt_hw_interrupt_disable(void);
void rt_hw_interrupt_enable(rt_base_t level);
#endif /*RT_USING_SMP*/

rt_base_t rt_cpus_lock(void)
{
    rt_base_t level;
    struct rt_cpu* pcpu;
    level = rt_hw_local_irq_disable();
    pcpu = rt_cpu_self();
    if (pcpu->current_thread != RT_NULL)
    {
        register rt_uint16_t lock_nest = pcpu->current_thread->cpus_lock_nest;
        pcpu->current_thread->cpus_lock_nest++;
        if (lock_nest == 0)
        {
            pcpu->current_thread->scheduler_lock_nest++;
            rt_hw_spin_lock(&_cpus_lock);
        }
    }
    return level;
}
RTM_EXPORT(rt_cpus_lock);
