Ubuntu 22.04 上的分段错误

  • 772

我在 Ubuntu 22.04 上遇到了分段错误，想寻求帮助进行调试。

我有一些运行sudo apt-get update：Segmentation faultsts... 52%

运行软件更新程序我得到：update-manager crashed with SIGSEV

另一个例子是删除 conda 环境。

有时在spyder中运行python脚本：

/home/max/anaconda3/envs/spyder-env/lib/python3.11/site-packages/spyder/plugins/ipythonconsole/scripts/conda-activate.sh: line 18: 1216748 Segmentation fault      (core dumped) $CONDA_ENV_PYTHON -m spyder_kernels.console -f $SPYDER_KERNEL_SPEC


Fatal Python error: Segmentation fault

Restarting kernel...

此外，其他程序（如 Visual Studio 或 Google Chrome）崩溃时没有出现错误。

我试过：

  • 重新安装 spyder
  • 创建了一个新的 conda 环境并重新安装我使用的所有包。
  • 冉conda clean -a
  • 使用 apt-get 运行更新和升级
  • 运行 memtest，没有出现任何错误
  • 对 CPU 进行压力测试
  • 尝试在恢复模式下修复导致分段错误的损坏包。
  • 更新 BIOS
  • 升级到 Ubuntu 24.04

以下是删除 conda 环境时发生分段错误后出现的日志（journalctl）的摘录：

有人对如何找到这个问题的根源有什么建议吗？我也可以重新安装 Ubuntu，但我想了解发生了什么。

    这似乎是 CPU 的一个错误。

    如上所述，journalctl --since "10 minutes ago" -k显示了每个分段错误的错误。错误始终指向同一个 CPU：CPU 4 (core 8, socket 0)

    通过lscpu --all --extended，我发现这对应于核心 2（https://stackoverflow.com/questions/71122837/how-to-detect-e-cores-and-p-cores-in-linux-alder-lake-system）。

    然后我就能够在 BIOS 中关闭这个核心。

    对于 CPU（第 13 代 Intel Core i9-13900KF），核心 2 对应于 P 核心 2。在 BIOS（主板华硕 ROG STRIX Z690-E GAMING WIFI）中，我更改了：

    高级 -> CPU 配置 -> 每个 P 核控制 -> 已启用

    然后

    高级 -> CPU 配置 -> P-Core 2 -> 已禁用。

    系统目前运行正常，没有分段错误。
