大家好，我的程序之前还挺好的，后来不知道动了什么，就一直停在主核向从核发message那里， 困扰了我好几天了，现把截图贴到这里，请大神么给看看，谢谢了！

从核提示hwi堆栈溢出了，主核提示cache_wbInv那里出错，但是我的cache_wbInv操作都删掉了，还是会出错！

    补充：主核运行到   if (MessageQ_put(queue_id[i], (MessageQ_Msg)p_msg) < 0)就崩溃了，暂停之后弹出TransportShm.c文件指向

    Bool TransportShm_put(TransportShm_Object *obj, Ptr msg)函数里面的这条语句

    /* make sure ListMP_put and sendEvent are done before remote executes */
    key = GateMP_enter((GateMP_Handle)obj->gate);

    还有Cache.c里面的

    Void Cache_wait()
    {
    /* wait for L2 word count to be zero */
    while (*L2WWC != 0) {
    ;
    }

    /*
    * Stall CPU while memory system is busy.
    */
    _mfence();
    }

    停在while语句那里，请问我到底错在哪了？
