两周前，我在 HP Proliant dl380 gen 9 上安装了 Ubuntu 14.04 LTS。自从我安装以来，它在白天自动断开连接并在晚上和周末再次连接（在高峰时段断开连接）一直表现不佳。如果我在白天拔下并插入网络电缆，它往往会连接几分钟然后断开连接（同时在网络区域上显示已连接的图标）。命令的输出lspci -knn | grep Eth -A2返回

终于通过14e4:1687 Broadcom tg3 network driver在高负载下断开连接找到了答案。使用 ethtool 禁用 highdma 似乎可以解决这个问题，使解决方案永久添加 /etc/udev/rules.d/70-persistent-net.rules 中的 udev 规则：

ACTION=="add", SUBSYSTEM=="net", ATTRS{vendor}=="0x14e4", ATTRS{device}=="0x1687", RUN+="/sbin/ethtool -K %k highdma off"
