播放普通视频没有问题，当播放高清视频时出现内核崩溃，但是能播放几十秒，每次必然崩溃。
应用程序没有任何错误信息，以下信息全部是内核打印的，每次栈的深度不一定一样：

Kernel panic - not syncing: Fatal exception in interrupt

请问各位知道该从何入手？谢谢。

看起来应该跟网络有关，估计在本地播放不会有问题

nfs_pageio_doio与__netdev_alloc_skb这两个函数值得跟踪调试下，跟内存相关。

估计是内存溢出问题，具体不清楚。

好好看看这个原因

楼主，对于kernel panic的信息，每次都不同，比较难定位问题。
换了新CPU出现的(同时文件系统和各种库也换了)。从新cpu, 文件系统，库方面着手吧。
