了解 dmesg 警告

  • 772

任何人都可以在下面的 dmesg 日志中对这些警告的含义提供一些见解吗？他们的意思是 atl1c 模块无法完全加载还是只是一个警告？

任何有助于更好地理解日志的信息将不胜感激。

谢谢你。

    该日志是来自内核的警告，表明内核代码中的某处可能存在错误。

    它告诉你有东西试图释放 IRQ 18，即使它之前已经被释放了。当你反复出现这种情况时，它表明某些东西正试图一次又一次地释放它。

    Comm: 字段显示它在运行ifconfig命令时，即配置网络接口。

    调用堆栈还表明部分代码在atl1c内核模块中，我相信它用于 Atheros L1C 千兆以太网，这是一个网络适配器。

    所以那里似乎有足够的相关性来暗示该设备驱动程序中某处的错误。

    另一方面，内核消息只是一个“警告”，因此它可能不是真正的错误（或会导致问题的严重错误），而是驱动程序设计的更多问题（也许它正在释放由于某种原因反复IRQ...）

    在 Google 中搜索其中一些术语并没有真正出现太多......所以不确定这是否是一个已知问题。

    内核 3.10 已经很老了……可能这个问题已经被修复了，所以也许尝试一个更新的内核（如果你可以选择的话）可能是个好主意。
