我正在运行 arch linux 内核 6.6.8-arch1-1，并且我似乎随机地（每隔几天）失去互联网连接。除了重新启动之外，我不知道有什么方法可以成功恢复网络连接。 （重新启动 systemd-networkd 不会恢复连接）
这个问题不断发生，但我不完全明白 dmesg 日志在说什么。
我认为内核正在禁用控制以太网端口的模块，或者模块可能崩溃了？
我已尝试更新 BIOS 固件，但未能解决问题。
这个问题是由于主板本身的故障还是由于使用了一些实验性封装架构？我可以使用包管理器回滚某些包版本吗？我不确定我还能做些什么来解决这个问题。如果我在下面发布的内容还不够，也许我可以开始记录一些内容以获取更多详细信息？

我尝试切换到 linux mint，以防这个问题特定于 Arch。不幸的是，我又得到了它。 dmesg 输出看起来非常相似。我猜这是主板特定问题。我不知道如何报告潜在的驱动程序错误。我想我必须选择不同的主板。
