我在联想 ThinkPad P52s 上运行 Ubuntu 18.04.4 LTS。由于日志文件（syslog 和 kern.log）太大，系统空间不足后会崩溃，这些日志文件会反复显示相同的消息。发生这种情况时我可以恢复，但这种情况大约每两天发生一次。
下面是一些系统信息和重复的日志消息。我见过类似的邮政但使固定似乎具体涉及 PCI 问题。

kern.log 中的消息类似。
在日志中搜索 AER。
grep -i AER /var/log/syslog*
/var/log/syslog.1:Jun 23 09:26:36 torres kernel: [ 0.595197] acpi PNP0A08:00: _OSC: platform does not support [AER]

答案1
BIOS
您的 BIOS 版本为 N27ET35W (1.21 )，发布日期为 2019 年 4 月 30 日
有较新的 BIOS 可用，版本 (1.24)，日期为 2019 年 12 月 19 日，可以下载这里。
注意：请确保我有您型号的正确网页。
注意：更新 BIOS 之前请做好备份。
注意：不能保证这一定能解决您的问题，但这是第一步。
