惊慌失措；Oops:0000[#1]"；（查看日志了解详细信息）-更新的内核测试

我试图解释一个可重复的系统崩溃，但不是经常发生。我相信这与第三方驱动程序和光学扫描设备有关。我不确定扫描设备的驱动程序是否导致了挂起，如果它在USB驱动程序中带来了导致挂起的东西，或者是完全不同的东西

我不是一个驱动程序开发人员，所以我在这里阅读Linux内核崩溃手册的时候，在崩溃转储中摸索

我能够使用kexec工具设置调试内核以生成vmcore。在崩溃时，可以看到恐慌：“Oops:0000[#1]”（查看日志了解详细信息），在日志中可以看到错误：无法处理虚拟地址00100处的内核分页请求

你能帮我解释更多的转储，这样我就可以回到驱动程序的开发人员那里，告诉他们结果吗？或者你能告诉我根本不是驱动程序吗

这里有更多的垃圾。非常感谢

Oops:0000表示找不到页面。处理中断时，故障处于内核模式。堆栈上有几个函数，但崩溃发生在hiddev_report_event（）中的某个地方——可能是在处理一个包含伪成员的链接列表。这是我看帖子时的感受。谢谢你，彼得。正如您可能已经看到的，我们有一个带有第三方驱动程序的受污染内核。崩溃就发生在我们试图读取扫描时，所以你认为这是第三方驱动程序的问题，还是我们暴露了内核USB驱动程序中的某些内容？我知道这些都是模糊的问题。如果你能给我一个小方向，让我深入挖掘，我将非常感激你好，安东尼奥不会太关注那个“受污染”的司机。这意味着，除其他外，它可能不是内置在股票内核中的开源软件。许多/大多数受污染的驾驶人功能正常。其他一些东西可能会污染内核。我猜这个错误是由于内存缓冲区管理不善造成的。你好，Peter L。如果你在那里的话。你能看看我原始问题中编辑的信息吗？我已经更新到最新发布的CentOS 5.5内核（2.6.18-371.6.1），但仍然出现了内核恐慌。然而，这次死机发生在命令“khubd”上，而不是“swapper”上。我能够捕获垃圾场，并提供了我希望的相关信息，以查明这个问题。它是内核中的bug还是驱动程序中的什么？谢谢，Antoniokhubd是USB集线器守护进程。它可能不是崩溃的根源，很可能是一个有缺陷的USB驱动程序。顺便说一句，“swapper”是一个始终在运行的进程，它经常以当前状态出现在崩溃转储中，但也几乎从不出错。看起来设备可能在崩溃时已断开连接。信息不足
