首先，在我的台式机上运行 Ubuntu 22.04（内核 6.5.0-14）和 VirtualBox 7.0.14，一切正常。没有错误消息。但如果我在笔记本电脑 ThinkPad T450s 上尝试相同的组合，我会在系统日志中收到以下消息以及数百条类似的消息，一个接一个：

答案1
“解决方案”是重新启动回到 6.2.0-39 内核，一切运行正常。
只是这个解决方案只适用于笔记本电脑。在台式机上它不起作用，因为我有多个显示器，而最近（几天前）升级到 Ubuntu 22.04 破坏了 X11 支持中的某些功能，因此即使我在 /etc/gdm3/custom.conf 中禁用 Xwayland，我仍然无法使用 6.2.0-39 启动并使用多个显示器，而且只能使用 1024x768 分辨率，而不是原生 4K。因此在台式机上我必须使用 6.5.0-14 启动并忽略系统日志中的错误消息。虚拟机似乎运行良好。
