系统日志中每天有 35 GB 的“PCIe 总线错误：严重性=已更正，类型=数据链路层...”
  • Ubuntu 20.04.4 LTS
  • 戴尔 XPS 8940
  • 最新 BIOS 2.4.0

新安装，系统似乎运行良好，但我每天收到 35 GB 的系统日志错误消息，例如：

看起来您的 Nvidia 卡导致了系统日志问题。

尝试 Nvidia 510.54。如果您可以使用其他显卡，请尝试使用其他显卡。

要消除系统日志噪音，请执行以下操作...

sudo -H gedit /etc/default/grub# 编辑此文件

寻找：

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

更改为：

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=noaer"

保存文件。

sudo update-grub# 更新 GRUB

reboot# 重启计算机

更新＃1：

通过关闭 ASPM 修复：pcie_aspm=off
