我在我的三星 Galaxy Note 2 LTE 上遇到了这个问题，随机重启和内核日志中的某种干净重启（没有 oops / 恐慌，即使有一些 USB 错误），现在我在 last_kmsg 日志中遇到了内核恐慌。在这个日志中，我发现了 10 次启动调制解调器的尝试，但都失败了，之后内核出现了恐慌，因为重新启动超时。
5.5 秒间隔重复调制解调器启动序列：

之后，引导加载程序启动。
这是完整的 last_kmsg 日志。
我怎样才能获得内存转储（据我了解，从阅读有关桌面 linux 内核调试的信息来看，这是需要的）来分析我的 Android 设备上crash或bt在我的 Android 设备上出现恐慌的确切原因，或者他们是解决回溯的另一种方法吗？
或者我什至应该做一些不同的事情来确定这是硬件问题还是仅从当前日志中说明的软件部分有什么问题？
任何帮助深表感谢！
