所以我刚刚安装了 CentOS 8，但我总是遇到随机冻结/崩溃的情况。我尝试查看我的/var/log/messages，但找不到任何有用的东西。崩溃的发生不一致，我无法通过执行特定过程来复制它。当我查看 dmesg 时，我经常看到某些内容，但我不确定实际问题是什么以及如何解决它，即使在 Google 和 Stack Exchange 搜索之后也是如此。这是我的 dmesg 转储，因此如果有什么我应该深入研究的内容，请告诉我，或者是否有其他地方我应该查看。我应该提到的一件事是，在过去的 dmesg 转储中，我看到 PulseAudio 遇到了麻烦，但我不确定这是否重要。如果有用的话我可以找到并复制到这里。
