这实际上从 16.04 生命周期的某个时刻开始就一直存在问题，最初 16.04 没有这个问题。暂停后，我无法连接到有线网络连接。我以为我安装了一些东西来破坏它，但最近一个月左右我玩了一些 Ubuntu 变体（Pop!_OS、Elementary、Ubuntu、Kubutnu）所有最新的稳定版本，问题仍然存在。当然有一些类型的日志可以提供硬件信息，但我需要一些帮助来弄清楚。我怀疑这是我的特定硬件的问题。
我刚刚安装了 20.04 Kubutnu。硬件列表和内核信息作为开始：代码：

有什么想法吗？谢谢
答案1
您可能遇到了内核问题，或者 sky2 以太网驱动程序问题。
注意：如果由于某种原因它不起作用，您可以随时删除创建的 /etc/modprobe.d/sky2.conf 文件，然后重新加载 sky2 驱动程序。
正在terminal尝试...
echo "options sky2 disable_msi=1" | sudo tee /etc/modprobe.d/sky2.conf
sudo modprobe -r sky2
sudo modprobe sky2
然后测试暂停/恢复和以太网。
注：或者使用内核参数“sky2.disable_msi=1”启动
