TI中文支持网大家好，我定制了linux内核，发现启动最后显示如下错误，但是系统是可以起来的只是每次都会有一下错误信息：
UBIFS: completing deferred recovery

Steven Liu1：
UBIFS做的有问题。你是用UBIFS来做的文件系统尝试启动的吗？
还是用其他的方式，如果是用UBIFS做的文件系统来启动，应该就是在这里出了问题。对应着这个来做问题配置确认吧：

可以参考下面的ubifs wiki网站。http://processors.wiki.ti.com/index.php/UBIFS_Support#Creating_UBIFS_file_system
