我已经在arch linux上运行了一个全新的系统大约3个星期,昨晚它自动重启.

在重新启动时,在journalctl中没有关闭/暂停,所以我很确定这是与硬件相关的,而不是用户空间程序或acpi.

journalctl
Jul 01 06:21:15 euclid sshd[25731]: ...
-- Reboot --
Jul 01 06:24:46 euclid systemd-journald[305]: Time spent on flushing to /var is 547us for 0 entries.

然后,在开机期间,

Jul 01 06:24:46 euclid kernel: .... node  #0,cpus:        #1  #2  #3

Jul 01 06:24:46 euclid kernel:   #4  #5  #6  #7  #8  #9 #10 #11 #12 #13 #14 #15

当我尝试运行mcelog时,我明白了

0 % mcelog
mcelog: ERROR: AMD Processor family 23: mcelog does not support this processor.  Please use the edac_mce_amd module instead.
cpu is unsupported

我怀疑要么1)我为这个系统缩小了PSU,或者2)在某个地方过热.

我运行的所有PSU计算器给了我750W的推荐值,所以我使用了850W的PSU.不过,现在我正在考虑升级到1000W的PSU.

我的问题是,如何解释机器检查事件？我想这是我的cpu特有的？ AMD是否提供了任何可以解码该错误的信息？而且,我怎么知道我是否因为过热而重新启动？我无法在BIOS(华硕)中找到任何事件日志.

没有超频.库存BIOS设置.

它稳定运行了几个星期.事件发生前几天我确实增加了3倍硬盘.

编辑：同样的崩溃似乎再次发生
