操作系统：Ubuntu 19.10
核心：5.3.0-26-通用
机器：戴尔 7590
BIOS 信息：版本：1.5.0，发布日期：2019/12/25
侏儒：3.34.2
描述：从 2020 年 1 月 15 日开始，我正在更新 OLED 屏幕亮度脚本，然后在凌晨 1:50 进行了更新，需要重新启动，BIOS 运行更新实用程序，几个小时后或更短时间后，机器开始出现随机冻结，需要硬关机。下面你会发现syslog最后一次发生在 2020 年 1 月 19 日下午 4:00 的事件的前后情况。也检查过了dmsg，但没有发现任何错误（除了常见的东西）。
尝试过的解决方案（没有成功）：
- 使用旧内核版本登录。
- 删除我的脚本。
- 阅读日志文件（syslog、dmsg、apt）寻找任何线索。
- 搜索类似问题，发现这个，但这并不是完全相同的问题。
更新 1： 我相信这个问题与最近的 Ubuntu 软件中心 BIOS 更新有关，因为我的 BIOS 发布日期是 2019 年 12 月 25 日。但是戴尔网站显示当前可用的 BIOS 是 2020 年 1 月 14 日。发布了另一个关于如何检查 Ubuntu 软件中心 BIOS 日志的[问题][3]。
更新 2：
一条评论提到其他用户也遇到了这个问题，怀疑是 的案例kernel 5.3.0-26。我检查了一下，发现 是kernel 5.3.0-26在问题发生的前一天（2020 年 1 月 14 日）安装的。
更新 3：
2020 年 1 月 28 日，新内核5.3.0-29-generic已经可用，但机器再次冻结。
更新 4： 找到了这个[answer][4]，但似乎只是滞后几秒钟，而不是整个系统冻结。
更新 5：BIOS经过几次更新后，问题已经消失，将检查原因并添加。但这肯定不是问题，可能是内核问题，我的是5.3.0-40-generic现在的版本。
更新 6：问题仍然存在，但是当我连接到雷电 3 基座时它就消失了。无论如何，现在我有一个全新安装的 ubuntu 20.04，它看起来很稳定。
