log 不是查 bug 的？看看硬盘空间，内存占用？

老电脑的问题比较复杂，建议烤机+u 盘启动 memtest 看看有没有硬件或者散热方面的问题

@everyx 显然这台不是，查型号应该是 3 代 i5

发现很多人确实不会看日志啊，kern 报的日志全都来自 Ath 网卡，目标明确还有啥好猜的

同样的问题，最开始是大概 6 天左右就死机，后来升级了内核，好了一些，最多坚持到了 19 天，现在写了脚本检测挂了自动重启

mingl0280

2023-04-23 15:28:27 +08:00 via Android

dmesg 看看呢？

flush9f

2023-04-23 15:34:17 +08:00

开 kdump 或者用 usb 采集卡抓屏幕录像来看 backtrace ，看日志就纯纯靠猜了

2023-04-23 16:32:23 +08:00 via Android

之前有个联想小主机，经常死机还查不到日志，后来有一次屏幕显示 CPU 没响应，更新了一下 TPM 就好了

我有台 Acer 老笔记本装 Ubuntu/Win10 都会经常死机。看上去是散热的问题。也没办法搞定。只能装自带的 Win7.

@chionetw5 8G 内存，常年空闲 6G ，硬盘也是 320G SSD 应该不可能这方面有问题 ...

我的一样,不过是 i7 6700K 台式机，连装系统都报错装不上，还是把硬盘装在其它电脑上才装上的系统，也是动不动就死机了.现在改用 WSL 2 了

/tmp 目录会不会满了？重启 /tmp 为空就不会死机
