我在戴尔 Latitude 7490 上安装了 Ubuntu 16.04，遇到了硬件问题，所以戴尔更换了主板。之后，Ubuntu 无法启动，所以我不得不将 SATA 配置更改为 AHCI，而不是默认的 RAID。现在 Ubuntu 可以正常启动，但我遇到了另一个问题：它在从睡眠状态恢复后崩溃。这是 kern.log：

有人知道什么会导致崩溃/冻结吗？ 似乎 ACPI 有很多异常和错误，但我真的不知道这意味着什么。

我现在已经更新到 Ubuntu 20.04，希望它能解决这个问题，但......它没有！更糟糕的是，现在 kern.log 中什么都没有出现，最后一条消息是它进入了“挂起”模式：

我真的迷路了，不知道如何进一步调试。有人能帮帮我吗？
答案1
好吧，这可能不是适合所有人的解决方案，但这是我的解决方案。我降级到 Linux 内核 5.4，现在我不再遇到睡眠后冻结的问题，而且我也遇到了很多 Wifi 问题，现在这些问题已经不再存在了！所以对于未来的读者来说，这是一个坏消息，我没有解决 16.04 中 AHCI 问题的方法。这可能也与内核错误有关。
由此讨论，似乎很多人在全新安装 Ubuntu 20.04 时自动安装了内核 5.8，这给不同的人带来了各种问题。所以我想说我属于这一类。
为了完整起见，我降级到了，5.4.101因为讨论说 5.4 是服务器应该使用的 GA（通用可用性）版本（即它更稳定）。
顺便说一句，我发现了非常有用的 GUIUbuntu 主线内核安装程序（mainline包裹）。
