最近更新后，我的笔记本电脑在启动后几个小时内开始随机崩溃。当它崩溃时，最后一个图像保留在我的显示器上，但机器完全没有响应（数字锁定灯不更新）。我使用 Opensuse Tumbleweed，内核 5.12.2-1，Nvidia 驱动程序 460.73.01，Thinkpad P71 配备 Quadro M620 移动 GPU 和 i7-7700HQ。
在一个可能不相关的问题上，网络接口每隔几秒就会不断地启动和关闭。在崩溃的启动中，除了与网络接口异常相关的条目外，崩溃前的许多分钟内都没有 jourenctl 条目。我通过官方扩展坞使用内部以太网卡，由 NetworkManager 管理。这是崩溃前的一个journalctl示例，注意到同样的东西在日志中重复了几个小时：

请让我知道我是否应该去其他地方询问。我已经做了 RAM 测试，我不认为这是具有已知 cstate 问题的 CPU 之一，因为我已经使用这台机器一年多了。故障排除很痛苦，因为崩溃需要两到二十个小时，但我知道是否还有其他我应该尝试的事情。
答案1
在过去的一周里，我看到了类似的事情。这可能是从 kernel-default-5.12.13-1 和 Nvidia 驱动程序 460.84 开始的，但不是在安装后立即出现的，因此它可能与其他更新（plasma、chrome 等）有关。它在内核默认 5.13.0-1.1 上继续发生。在已经稳定运行相当长一段时间的桌面上，这种情况发生了三次。
几年前，Chrome 就为我引发了类似的事情。我已经关闭了 Google chrome-beta 92.0.4515.80-1 GPU 加速的高级选项。到目前为止，我还没有看到另一个锁定。但我现在也使用内核默认 5.13.0-1.2 和 chrome beta 92.0.4515.93-1，因此它们可能会改变情况。
我通常会在 nvidia 论坛中提出这个问题（我发现他们的支持人员过去非常有帮助）。但我会犹豫是否这样做，直到我在日志或 /var/log/Xorg.0.log 中看到模式或有趣的东西。如果您有最近崩溃中的 /var/log/Xorg.0.log，也许其中可能包含一些线索。
