自过去几天以来，Xorg 大约每天崩溃一次，完全是随机的。当它崩溃时，我的显示器变黑，几秒钟后 LightDM 的登录管理器弹出。
我使用的是 Arch 5.15.2、bspwm、nvidia 专有驱动程序版本495.44-9。内核和 nvidia 驱动程序最近都已更新，因此它们可能是原因。我的系统是 Lenovo Legion 5 Pro，带有Ryzen 7 5800H、RTX 3070 Mobile和16GB RAM。我使用两台外部显示器：一台连接到 HDMI，一台连接到 USB-C 输出。
奇怪的是，其中两次崩溃是在 Reddit 上观看视频时发生的，都是在突然发生非常响亮和高音调的事情时发生的。崩溃要么发生在巨响发生时，要么发生在我使用鼠标按钮快速降低音量时。我总是使用连接到 3.5 毫米端口的耳机（拜亚动力 DT 770 Pro 80 欧姆）。其他崩溃似乎是随机的。当显示器未插入时，我没有发生过任何崩溃，但我最近很少这样使用我的笔记本电脑。
查看journalctl，崩溃总是发生在这些 ACPI 插孔/视频输出和插孔/线路输出线之后：

完整输出journalctl -b：https://pastebin.com/aqevKaSV
这些 ACPI 视频输出和线路输出线似乎经常出现，但它们并不总是会导致崩溃。我想直到本周我才见过它们，而且我从七月份就拥有了这台笔记本电脑。
jack/lineout和ACPI 错误的含义是什么jack/videoout？我知道它们没有在 中定义/etc/acpi/handler.sh，但是是什么导致了它们呢？由于某些崩溃是在发生非常大声的事情时发生的，因此该问题是否与突然的大功率消耗有关？不过，压力测试似乎效果很好。
查看 Xorg 堆栈跟踪，崩溃似乎是在调用该
__restore_rt函数后发生的。这意味着什么？
答案1
我在 Arch Linux bugtracker 上创建了一个错误报告：https://bugs.archlinux.org/task/72799
现在似乎已修复。
