移植rtl8188到210，已成功，能够搜索热点并连接到网络，但是如果我在机器上面打开很多应用（各种耗内存的应用，比如Google map（卫星视图），微信）然后打开音乐播放，此时，如果打开wifi，有时候会出现死机现象，说内存分配失败。但是wifi驱动里面对申请内存如果失败都有错误处理的，我觉得不是wifi驱动着方面的问题，因为我移植另外一款wifi（rt3070）也出现这种问题，打开wifi，加载驱动后运行驱动的probe，然后就出现内核奔溃失败，接着就直接死机，rt3070的代码我也查看了，内存分配失败的时候是由出错处理的，会返回错误信息。曾经以为会不会是因为wifi关闭的时候，申请的内存没有释放，但是经过确认，每次关闭的时候，都将申请的资源释放了，所以我认为死机和三星平台向相关，而不是wifi驱动的问题。请问大家有没有遇到类似内存不足导致分配失败的问题？（wifi分配的内存属于DMA类型的）下面是有关死机时候的内核log信息：
