mt7921e 探测失败，错误为 -110

我有 Ubuntu 21.10，并且我设法让它与联发科 MT7921 无线适配器配合使用。但是，最近在重新启动我的机器后，我无法再使用该适配器，它就消失了。我不确定，也许是由某些更新引起的。我已经确认适配器在 Windows 11（双启动）中正常工作，因此问题出在 Linux 系统上。

这是什么原因造成的？我很乐意在第一次请求时提供更多详细信息。

答案1

联发科针对重启问题的补丁

这适用于我的华硕 zephyrus，希望能够很快成为主流。

答案2

mt7921e 探测失败，错误为 -110

这里可以观察到的错误消息dmesg是关键：

mt7921e: probe of 0000:05:00.0 failed with error -110。

一个非常类似的问题是之前曾报告为了iwlwifi。

看起来与 Windows 的双重启动会导致出现此问题。Windows 可能会将网络适配器置于某种状态，而 Linux 内核驱动程序无法恢复该状态并导致超时错误。

许多人报告说可以通过禁用 Windows 中的快速启动来解决此问题，但就我而言，这没有帮助。

解决方案

我发现让适配器工作的唯一方法是完全关闭电源Windows，而不是使用重启. 当冷启动开始时，适配器能够被Linux内核正确初始化。

如果您知道此问题的更持久的解决方案，也请分享您的想法。
