最近升级到内核 5.13.0-28-generic 后，我的系统仍然无法在没有“nomodeset”的情况下启动。我附上了 journalctl 的输出，希望有人能帮助我。我正在使用板载英特尔 WiFi 和图形硬件。我的系统有 iwlwifi 问题，我解决了这个问题
sudo mv /lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm /lib/firmware/iwlwifi-ty-a0-gf-a0.bak
如此处所示：
https://bugzilla.kernel.org/show_bug.cgi?id=212371#c13
以下是内核 5.13.0-28-generic 的启动日志，其中最先出现问题。请注意 CPU#14 的软锁定

Feb 04 11:00:42 europa kernel: watchdog: BUG: soft lockup - CPU#14 stuck for 53s! [systemd-udevd:590]
最近升级到 Ubuntu 内核 5.13.0-27-generic 后，我的系统在启动时挂在启动画面。我只能通过在 grub BOOT_IMAGE 命令行中添加 nomodeset 来启动它。我使用的是主板的板载英特尔视频支持，即没有视频显示卡。使用 nomodeset 启动后，我的两个显示屏卡在 1024x768 分辨率，两个显示器显示相同的视频。在桌面的“显示设置”下没有用于更改显示的选项。
我目前的解决方法是恢复到 5.11.0-27-generic 内核，一切正常。我有两个连接的显示器，分辨率为 1920x1080。
我希望能够修复此问题，以便能够升级到 Ubuntu 提供的新内核。
以下是我的系统的具体情况：

我认为最近的内核升级在某种程度上没有正确配置我的视频。
如果我可以提供任何进一步的信息，请告诉我。
感谢您提供的任何帮助和指导。

我的系统现在启动正常，甚至 WiFi 也正常工作！我决定尝试在系统中添加 GPU，并安装了 MSI RX6800。有趣的是，在我重置 CMOS 内存之前，计算机无法使用新 GPU 完成 POST。之后一切正常，我现在运行的是 5.13.0-37 内核。我怀疑，但尚未确认，需要重置 CMOS 内存一直是问题所在；特别是因为我在故障排除时升级了 BIOS。只是没有意识到这是必要的。所以就我而言，这个问题已经解决了。
