请教一个系统启动时rfs解压缩crc错误的问题（怪异）

Atlantiscw

各位：
      最近遇到一个怪异的问题，设备插着网线启动时（网络上有通讯数据），在解压缩RFS时总报CRC错误，有时会导致文件系统加载失败
      具体描述如下：
      只有设备网线与公司外网连接、或者与电脑直连且网络有数据通信时（如ping命令测试），才会出现故障；
      如果重新刷新较小的RFS文件系统，没有该故障；
      启动时，在板子的debug口进行监控，故障现象都是RFS解压提示crc error；
      怀疑是设备网络的内存地址与内存中rfs的存储区交叠导致数据被改写了，但检查网络驱动，在rfs加载前接收中断是被关闭的，也就是说应该没有任何数据被写入内存；
      但如果去掉网络模块中的TCP/IP协议栈，重新编译内核并更新后进行测试，可以正常启动。

      查了好久没有什么头绪，望各位能给些建议，多谢了！

以下是系统的启动信息：
