网络连接激活失败 - 从 Windows 重新启动时修复

  • 772

我有 Windows 10 和 Ubuntu 20.14 的双启动。

从前一段时间，我的电脑出现问题......当它在 Ubuntu 中启动时，有时会随机启动（我的意思是，大约 30% 的初创公司会出现问题）说Activation of network connection failed，这是一台台式电脑，所以我使用以太网端口。

当问题出现时，在网络上尝试一些解决方案并不能解决问题。我试过了：

  • 此处建议重新启用有线连接
  • 重新启动所有路由器 - 我有 2 个，连接方式如下：[ISP 路由器] <LAN 端口 - WAN 端口> [Tplinkrouter] <LAN 端口 - Eth 端口> [PC]。此处建议的解决方案
  • 重新安装网络管理器并重新启动：sudo apt-get install --reinstall network-manager ; sudo reboot now这里也建议

此外，真正有趣的是，当我从 Windows 10 重新启动到 Ubuntu 时，问题消失了，如果我从 Ubuntu 重新启动到 Ubuntu，那么问题又出现了......

关于我的系统的一些上下文：

  • Windows 10 快速启动被禁用
  • 双引导在 nvme 驱动器上
  • 这个问题永远不会出现在 Windows 上
  • sudo lshw -C network输出（未出现问题时）：

有什么办法可以解决这个恼人的失败？

提前致谢。

遵循@heynnema 解决方案：

步骤 1.将脚本“r8169_disable_msi”添加到/etc/initramfs-tools/scripts/init-top路径并chmod a+x对其执行以下操作：

要检查这里是否有ls -l /etc/initramfs-tools/scripts/init-top输出：

total 4
-rwxr-xr-x 1 root root 1118 mar 30 11:59 r8169_disable_msi

第 2 步。 “将 'r8169_disable_msi' 添加到内核命令行（/etc/default/grub, GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" 通常。）”所以我对 /etc/default/grub 文件进行了更改：

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
#GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash r8169_disable_msi"
GRUB_CMDLINE_LINUX=""

# 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
GRUB_GFXMODE=1920x1080

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

步骤 3. sudo update-initramfs -c -k $(uname -r)输出：

I: (UUID=64e37a0f-3360-471d-8c6d-02a5865d7e77)
I: Set the RESUME variable to override this.

步骤 4. sudo update-grub输出：

这个解决方案奏效了。

    链接速度

    您的以太网卡能够达到 1Gb 的速度，但只能以 100Mb 的速度使用。这通常表示电缆有问题，或者某些网络设备（如以太网集线器/交换机/路由器）无法提供 1G 速度。首先，检查您使用的是 5e 类或 6 类以太网电缆。

    sudo lshw -C network

    size: 100Mbit/s
capacity: 1Gbit/s

    以太网驱动程序

    已知 r8169 驱动程序存在一些问题。安装此驱动程序，看看情况是否有所改善。

    sudo apt update

sudo apt install dkms r8168-dkms

reboot

    MSI中断问题

    一些 r816x 以太网卡不能正确处理 MSI/MSIX 中断。如果需要，我们可能需要实施补丁来解决该问题。需要时提供信息。给我看看：

    lspci -nn | grep -i ethernet

    05:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 0c)

    这是所需的补丁。说明在脚本中。紧跟。

    # https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1779817

# filename: r8169_disable_msi

# Drop it in /etc/initramfs-tools/scripts/init-top and chmod a+x it. Add 'r8169_disable_msi'
# to your kernel command line (/etc/default/grub, GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
# usually.) 

# Remember to update-initramfs and update-grub as necessary.

# sudo update-initramfs -c -k $(uname -r)
# sudo update-grub
# reboot

# For the moment it disables MSI on everything with the ID 0x10ec:0x8168, as there seems to
# be no way to get the MAC version from userspace - and certainly not before the driver is
# loaded. Other PCI IDs may need adding..

disable_msi () {
    for i in /sys/bus/pci/devices/*; do 
        if [ $(cat $i/vendor) = "0x10ec" -a $(cat $i/device) = "0x8168" ]; then
            echo 0 >$i/msi_bus
        fi
    done
}

for x in $(cat /proc/cmdline); do
        case ${x} in
        r8169_disable_msi)
        disable_msi
