我有一台 f23 linux 机器作为开发服务器运行，过去几周我多次登录时发现它已被重置。有一次它就在我面前重新启动，似乎重置为 BIOS，然后再次开机。
这似乎每 2 或 3 天发生一次。服务器日志仅显示正常操作、cron 等，直到重置并重新启动；

然而日志中似乎有很多这样的消息；

我检查了 BIOS smbios 事件日志，其中只有重启代码 0x17 显示机器在重置后启动，并且没有像我预期的那样注册任何内存重置。
不幸的是，该机器不支持IPMI，因为主板是超微X9DAi
我不确定如何解释该硬件错误消息中的错误代码，但似乎 0000:80:02 对应的是；
[root@pc03 ~]# lspci -s 0000:80:02
80:02.0 PCI bridge: Intel Corporation Xeon E5/Core i7 IIO PCI Express Root Port 2a (rev 07)
我目前正在监控服务器的温度/CPU，因此下次服务器崩溃时，我会对传感器的状态有一个很好的了解。我还可以采取其他步骤来确定此次崩溃的根本原因吗？
