以太网初始化失败

Question

我的以太网有问题。它无法连接。从本网站的其他答案中，我收到以下消息。

lspci -nn | grep 0200

rtl_counters_cond 似乎每隔几秒或几分钟重复一次，并在输出中持续数十行。我已经截断了它。

请帮忙。

Answer 1

我遇到了同样的错误，并通过重新加载网络设备的驱动程序来解决此问题。首先需要找到合适的pci设备：

find /sys/devices -name enp3s0

我有/sys/devices/pci0000:00/0000:00:1c.2/0000:03:00.0/net/enp3s0。然后删除 pci 设备并重新扫描总线：

echo 1 >/sys/devices/pci0000:00/0000:00:1c.2/0000:03:00.0/remove
echo 1 >/sys/devices/pci0000:00/0000:00:1c.2/rescan

完成，网络接口重新初始化。

我得到了下一个内核日志：

您可以通过其他方式尝试重新加载驱动程序本身，如下所示rmmod r8169; modprobe r8169：我没有尝试这个，因为我有第二个类似的网络设备用于 ssh。
