我用gdb调试，出错行是在函数__list_del()函数里面。

是在88行。next->prev = prev;

还有几个其它的oops信息，但是出错行都是在__list_del里面！！！！

请大家帮看一下是什么问题，应该从哪里入手。。

声明对ARM不太熟悉

这个内核是你们改动过的内核吧？是不是只是操作与某个驱动相关的资源才会出现这个问题？

机器放久了，会出现oops出错死机问题。

Unable to handle kernel NULL pointer dereference at virtual  ...

遇到过几次，但尚未找到比较好的高效定位方法，多半是内存越界导致页表损坏，但是如果是越界的话，比较难捕捉到越界的时机。
建议先去掉内核中的三方模块，或者恢复成标准内核观察是否还会出现，依次排查是否是三方模块或者自己修改内核导致的，逐步排查。
另外，有vmcore的话，可以看看被损坏页表地址范围附近的内存分布情况，如果是内存越界导致的话，罪魁祸首使用的内存通常就在附近~

是改动过的，开机放在那里，时间久了就会出现oops死机。时间不太确定，大概4-5小时吧。

如果能够定位到某个驱动，那就好办一些了。

从出错的PC值来看，是__list_del()函数出错。但是不知道是在哪里触发的！！

建议搜集vmcore尝试分析一下，主要关注被修改页表内存附近的内存分布情况(看什么模块占用了附近的内存)。

samyoju

比较奇怪的是，每次出现的oops信息不一样，但出错的PC值用gdb定位到的函数就是__list_del()函数。
如果硬件上面ddr有问题，比如某一时候出现干扰，会导致这些问题吗？

   我的环境是 linux2.6.37 + android2.3.4
