按照手册配置内核不能运行 有错误提示

我不知道TQ2440提供的linux2.6.30内核镜像文件中 在配置内核时有没有加上对V4L和usb摄像头的支持 如下：
Device drivers-->multimedia devices-->
Video capture adapters-->V4L USB devices-->
<*> USB OV511 Camera support

所以我就在内核源码中重新自己配置内核
但是按照手册上配置后 下载到开发板运行后出现如下错误：

希望朋友们能告诉一下  并且如果有配置好带V4l内核文件 请提供一下 谢谢了

看打印信息，你是nfs挂载的文件系统么？
可能跟挂载有关。
