lede I225-v B3 2.5G口老是断流重启是怎么回事？

rt, 新到的N5105 4网口软路由，配的225-v B3 网卡，发现网卡经常随机断流重启，怎么回事啊？设备用风扇吹着，CPU才50多度，照例说不热，之前用的5.10的内核，看网上说升到5.15内核就好了，现在升到5.15版本，发现还是重启啊，一重启就要重拨号断网了，是驱动的问题吗，麻烦大佬看看。附送内核日志，那些寄存器dump的值看不懂，没手册。

下面是一次完整的断流系统日志，我也不知道到底是I225 v3的驱动有问题还是硬件问题？当时正在做iperf3 测速，一下就网口重启了。现在集成在openwrt里的I225网卡驱动是最新的或者是相对稳定的吗？

请大佬们看下目前原生的I225-v B3的驱动程序是不是intel最新的哈？好像是kmod-igc这个，也不知道怎么看版本，这个网卡的操作温度才70°，也是醉了。感觉这个网卡真是拉跨，从B1到B3还是这个尿性，看来英特尔的研发解决问题的能力也很堪忧。

May 09 '22 00:05 GreatMichaelLee

用ESXi 7.0，开虚拟机跑OpenWrt，用虚拟网卡VMXNET3。我用虚拟机跑OpenWrt，i225-V B3从来没断过流。

May 09 '22 09:05 iKira

都遇到过断流情况，而且在短时间里不连续不断的出现了三次

May 10 '22 17:05 shu0802

虚拟机没有这个问题pve我还是用的老内核5.4的

May 11 '22 00:05 sbwcwfhv001

说明对虚拟设备支持得好，对物理设备反而支持得不好

就是驱动没写好

d79af96f27c2195bb3a85819bc17eef 5.15.38继续出现这问题

May 11 '22 11:05 shu0802

5.15.38继续出现这问题

我换7类线+加强力大风扇，目前来看貌似缓解了。这玩意估计多半就是网卡体质问题，网卡离CPU太近，而且本身也容易发热，它操作温度只有70度，温度一高，再加上如果接的网线如果屏蔽不好干扰大的话，估计驱动就容易gg。可以参考一下。虚拟机问题少，可能是虚拟机在外面的驱动包了一层，不容易直接引发问题

May 12 '22 02:05 GreatMichaelLee

用的PVE虚拟机，同时还直通了网卡，没发现问题，N6005，运行了快半个月了

May 13 '22 06:05 596142041

有没有找到官网上的网卡驱动，想手动安装试试。

rt, 新到的N5105 4网口软路由，配的225-v B3 网卡，发现网卡经常随机断流重启，怎么回事啊？设备用风扇吹着，CPU才50多度，照例说不热，之前用的5.10的内核，看网上说升到5.15内核就好了，现在升到5.15版本，发现还是重启啊，一重启就要重拨号断网了，是驱动的问题吗，麻烦大佬看看。附送内核日志，那些寄存器dump的值看不懂，没手册。

从来就没认为225网卡好。哪来这么多b3。你看j4125的210都比225贵。还是买210吧。

我的j4125 i225 b3 没断流过

May 20 '22 11:05 pipihu

225被称为软网卡，也不知道是不是这样，目前看来还是螃蟹的2.5 稳定的多，英特尔在2.5网卡看来是拉夸的很
