一个WIFI驱动引起的内核错误oops请教

只看该作者 · 2015-12-3 22:36

最近在PC和S3C6410下调RT3070的驱动，想用一下ad hoc功能；
先采用了官方提供的V2.5.0.2版本，infrastructure模式，没什么问题，用ad hoc发现不断地断线；
换了一个新的版本V2.6.1.3，infrastructure模式正常；
Ad hoc可以稳定连接，但是我用ping进行长时间测试时，一直发ping包，发了2000个左右时，开发板的内核崩溃；
或者在Ad hoc网络中再加一个节点进来，一开始ping，那个新加入开发板内核的就崩了；
或者驱动运行在PC上，几乎是一ping就崩（当然驱动是分平台编译好的）；
自己也看了一下查找oops错误的方法，http://blog.csdn.net/heqiuya/article/details/7762482
但是没找到一个准确定位的方法。
有人能指导一下这个不，或者有经验分享一下？
