出现断网的时候，日志里就会出现kern.err kernel: [ 482.920900] ralink_soc_eth 10100000.ethernet eth0: transmit timed out
有时候又有这样的报错。。 但是这样的报错好像不会导致ssh中断，就是QQ会断线在重连。[ 105.024798] device wlan0 left promiscuous mode [ 105.029606] br-lan: port 3(wlan0) entered disabled state [ 105.445609] br-lan: port 2(wlan1) entered disabled state [ 105.451224] br-lan: port 1(eth0.1) entered disabled state [ 105.536451] device wlan1 left promiscuous mode [ 105.541236] br-lan: port 2(wlan1) entered disabled state [ 105.551211] device eth0.1 left promiscuous mode [ 105.556031] br-lan: port 1(eth0.1) entered disabled state [ 105.656458] device eth0 left promiscuous mode [ 118.119909] 8021q: adding VLAN 0 to HW filter on device eth0 [ 118.137278] device eth0 entered promiscuous mode [ 118.148073] br-lan: port 1(eth0.1) entered blocking state [ 118.153595] br-lan: port 1(eth0.1) entered disabled state [ 118.159639] device eth0.1 entered promiscuous mode [ 118.187062] br-lan: port 1(eth0.1) entered blocking state [ 118.192587] br-lan: port 1(eth0.1) entered forwarding state [ 119.158793] IPv6: ADDRCONF(NETDEV_CHANGE): br-lan: link becomes ready [ 124.729346] ieee80211 phy1: rt2800_rf_self_txdc_cal: Info - RF Tx self calibration start [ 124.738179] ieee80211 phy1: rt2800_rf_self_txdc_cal: Info - RF Tx self calibration end [ 126.847211] ieee80211 phy1: rt2800_loft_iq_calibration: Info - LOFT Calibration Done!

7620a单核580mhz终究是老了，回4.14内核吧
这跟老不老没什么关系，顶多带不动多台机器，同样的内核隔壁x-wrt稳如狗，换L大的固件就断流，这是一个bug
7620a单核580mhz终究是老了，回4.14内核吧
顺便说下，官方固件纯净版5.10内核，加个科学插件仍然能带十几台电脑，暴力测试有线上下行跑满10M，也没断流，L大这边无论有线无线上下行还没跑1M就time out断流了 设备Youku L1C mt7620 16+128 官源内核5.10 有线百兆上下行跑满测试通过 X-wrt源内核5.4.162 有线百兆上下行跑满通过 immortalwrt源内核5.4/5.10跑满均通过
L大这边就惨了 优酷上下行还没跑1M就断流了 红米ac2100 上下行同时5-8M秒断
都是ralink_soc_eth 10100000.ethernet eth0: transmit timed out的问题，所以一定是bug，看了一下L大这边mtk的驱动，也是陈年老酒了，X-wrt那边直接用了mtk的驱动，所以估计L大也没法子，只能等L大同步上游了
其实你这个issue我以前就发过的，我觉得是交换机驱动的问题，后面编译了好几个固件，实在是烦了，就没弄了 https://github.com/coolsnowwolf/lede/issues/8046
