问题

我有一个新的HP Pavilion游戏笔记本,新安装了Ubuntu 16.04。当我按Ctrl + Alt + F1组合键时,我得到错误,不允许我与控制台进行交互:

我还会在每次启动时看到这些错误,

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

答案1

试试这个

使用此链接(关于在内核中添加参数)可以暂时添加内核引导参数,并使它永久化。然后,

添加参数,pci=nomsi

重新开机。

如果问题得到解决,那么使更改永久化。如果不行那就试试

pci=noaer

同样的方法,如果它有效的话。

原因与最新的英特尔Skylake架构CPU和Realtek rtl8723be无线适配器有关。


答案2

我使用ubuntu 16.04的文本模式


GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi"



这这对我没有帮助。我改变这里了-- (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



解决了我的错误(注意-我只使用了pci = nomsi,如果不起作用,其他选择是pci = noaer)。
