这个周末我甚至尝试过全新安装 Ubuntu，但崩溃仍然发生。我正在使用tlp，但我不认为这是导致问题的原因。
我使用的是内核版本5.3.0-26-generic。这是最新内核版本中已知的问题吗？有什么解决方法吗？
谢谢您的帮助

这附加驱动程序Ubuntu 中的窗口显示以下信息：

按照指示，我安装了backport-iwlwifi-dkms。安装输出如下：

我现在backport-iwlwifi-dkms使用以下命令删除了该包：
sudo apt-get purge backport-iwlwifi-dkms
编辑5
我还使用以下命令将内核升级到最新版本：
sudo apt-get dist-upgrade
我现在在内核5.3.0-29-generic。
最近几天我没有遇到崩溃。所以也许这有帮助。

答案1
我不知道 OP 最终是如何解决这个问题的，但我遇到了完全相同的问题。似乎发生在非常特定的硬件/软件组合上。我有：上周从头开始安装的 Ubuntu 19.10（之前从 19.04 等升级，也许这就是我现在遇到这个问题的原因），内核为 5.3.0-46-generic，戴尔 XPS 9570 中的英特尔 9260 Wi-Fi 芯片。如果我在启动 Ubuntu 之前启动了 Windows，似乎就会出现问题。
我读过错误https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1848921这似乎恰好可以解决这个问题。
短期对我来说，解决方案是上一条评论中提到的荒谬但有效解决方案：如果在 Windows 之后启动，请关闭机器，断开电源适配器，然后打开 Ubuntu。
长期对我来说，解决方案是升级到 Ubuntu 20.04 (LTS)，因为它将在几周后发布，并且似乎解决了这个问题（大约内核 5.4.16）。
如果这对于读者来说不可能（尽管在这种情况下您在运行 Ubuntu 时应该已经避免使用非 LTS 版本），您可以尝试错误讨论中提到的其他解决方案，例如：
- 确保 Windows 已禁用快速启动
- 为 iwlwifi 手动安装不同的固件：下载“-34”（
iwlwifi-9260-th-b0-jf-b0-34.XXXXX.X.tgz），“手动将包含的固件复制到 /lib/firmware，删除所有其他版本，并链接到内核需要加载的 iwlwifi-9260-th-b0-jf-46.ucode。”（参见错误描述） - 尝试配置
/etc/modprobe.d/wifi.conf上述选项这里 - 尝试不同的网络芯片（9260 除外）
- 升级或降级到不同的内核版本（AskUbuntu 有其他相关答案）。你可能已经安装了不同的内核，在这种情况下，你可以尝试启动它，看看问题是否仍然存在
