通过Buildroot创建东山派D1s的镜像后，通过网络接口写入文件出现死机情况

[story_xjj]

根据网上的buildroot创建了一个D1s的镜像，启动和运行都是比较正常的，由于东山派D1s没有网络接口，所以我利用RNDIS虚拟了一个网络，SSH可以正常登录，执行命令和查看修改系统的信息没有任何问题。在通过SFTP方式上传是出现了死机的情况，于是采用nfs链接windows的nfs服务器，可以正确链接，向windows的nfs服务器创建文件没有任何问题，但是向linux系统拷贝文件同样会出现死机的情况。

下面是系统打印的日志，请各位看看是什么原因导致的。

我还发现了一个怪现象，因为创建的SD卡镜像中，boot分区时fat格式的，如果用读卡器把文件复制到boot分区中，然后重新引导系统，挂载boot分区，再把文件复制到或移动到根分区中，就不会出现死机的情况。一切正常。
而且编译的文件可以正确执行。

问题有新的进展了，因为boot分区时fat格式的，我将boot分区挂载到root分区的目录下，然后通过sftp将文件传送到boot分区中，传送成功了，系统并没有死机。似乎这个文件复制过程死机和ext4文件系统有关系。原来传输的文件大小为5k左右，我把文件调大到10k，传输同样会失败。我现在也不清楚时文件系统格式的问题还是文件大小的问题，有没有大神可以出来指导一下。
