freescale的usb驱动启动的时候出问题，你可以把这个usb驱动先拿掉看看。

把出问题的内核模块干掉试试。

    谢谢，以下算是初始化完内存和中断了，那接下去的oops是什么，是网络部分吗？

现在问题出在topology_init。 系统在初始化系统多cpu拓扑结构时出问题。
你这样一步一步向前推很花时间。一般的做法是，下载一个能工作的版本， 尽量不做任何改动让这个版本先运行起来。从这个版本开始，逐步加上自己的模块。

    我这个板子也是自己做的，官方开发板是DDR2内存条的，我改成DDR3的了，现在不加模块驱动还好，一打开一个就出现如下一大堆内存初始化的问题，感觉无从下手啊
