PCIe总线错误严重性=已更正

问题描述

我有一个新的HP Pavilion游戏笔记本和一个新的Ubuntu 16.04安装。当我按下Ctrl + Alt + F1时,我开始看到下图中显示的错误,它不允许我与控制台交互:

16.04,ubuntu

我每次启动时都会看到这些错误一段时间。我需要按Ctrl + Alt + F1来访问非图形终端以安装一些Nvidia驱动程序。这是怎么回事?

导致该问题的原因似乎是:00:1c.5 PCI桥接器[0604]:Intel Corporation Sunrise Point-H PCI Express根端口#6 [8086:a115](rev f1)

最佳解决方法

试试这个,

使用此链接(about the adding paramter to kernel here)了解临时添加内核引导参数并使其永久化。然后,

添加参数pci=nomsi

然后重启。

如果问题得到解决,则将更改永久化。如果不起作用然后尝试,

pci=noaer

同样的方式,如果这有效,使其永久化。

(*外观原因与最近的英特尔Skylake架构CPU和Realtek rtl8723be无线适配器有关。

ubuntu团队了解它。点击此处了解更多信息Bug_track_ubuntu_PCIe bus error)

次佳解决方法

这里已经提供了答案,这也给了我很多帮助。我使用ubuntu 16.04的文本模式等等

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi"

没帮我我改变的是 – (在/etc/default/grub中)

GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
#GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi"
GRUB_CMDLINE_LINUX="text pci=nomsi"

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

# Uncomment to disable graphical terminal (grub-pc only)
GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480

这解决了我的错误(注意 – 我只使用了pci=nomsi,如果它不起作用,其他选项是pci=noaer),这可能有助于解决任何面临同样错误的人。
