我的三星Galaxy Note 2 LTE上出现this问题，随机重启并在内核日志中重新启动（没有oops / panic，即使有些usb错误），现在我遇到内核恐慌last_kmsg日志。在这个日志中，我认识到10次尝试启动调制解调器，所有这些都失败了，之后内核发生了恐慌，因为重启超时了。
5.5秒间隔重复调制解调器启动序列：

如何在我的Android上使用crash或bt分析内存转储（根据我从阅读有关桌面Linux内核调试的内容中所需的内容）来分析内存转储的确切原因设备还是他们解决回溯的另一种方式？
或者我是否应该做一些不同的事情来确定这是硬件问题还是单独从当前日志中说出哪些软件错误？
非常感谢任何帮助！
