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？

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: The initramfs will attempt to resume from /dev/nvme0n1p6
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。
