PCIe 总线错误严重性=已更正

Question

我有一个新的 HP Pavilion 游戏笔记本和一个新安装的 Ubuntu 16.04。当我按 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进行交互：

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

导致问题的原因似乎是：00:1c.5 PCI 桥 [0604]: Intel Corporation Sunrise Point-H PCI Express Root Port #6 [8086:a115] (rev f1)

Answer 1

尝试这个，

使用此链接（关于在此处向内核添加参数）了解如何临时添加内核引导参数并使其永久化。然后，

添加参数， pci=nomsi

并重新启动。

如果问题得到解决，则使更改永久化。如果不起作用，请尝试，

pci=noaer

以同样的方式并使其永久有效。

（*出现原因与最近的 Intel Skylake 架构 CPU 和 Realtek rtl8723be 无线适配器有关。

ubuntu 团队知道这一点。在此处阅读更多信息Bug_track_ubuntu_PCIe 总线错误）

Answer 2

这里已经提供了答案，这也对我有很大帮助。我使用 ubuntu 16.04 等的文本模式

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi"

没有帮助我。这里我改变的是——（在/etc/default/grub）

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相同错误的人。
