kernel: 5.4.68 编译的固件PPPoE频繁断连

[Ljzkirito]

Q：是否搜索了issue (使用 "x" 选择)

• 没有类似的issue

2. 详细叙述

(1) 具体问题

A：昨天更新源码后，保留配置升级，PPPoE频繁断连，关闭Flow Offloading没有效果，自己Fork到自己仓库，Revert "kernel: bump 5.4 to 5.4.68 (#5555)"后正常。

(2) 路由器型号和固件版本

A：XY-C5，最新源码，Github Actions编译

(3) 详细日志

A：在18：00时，概览虽显示PPPoE已连接，但此时已经断网

我的XY-C5也遇到这个问题，启动后大概10多分钟就丢失了pppoe-wan连接，看日志是peer发了LCP reset

[Myoko]

旧内核升级到新的内核 还是建议别保存配置升级！

不保存配置也是一样的，下面是系统日志

HC5962，跟你问题类似，wan+man方式，man有问题，关掉man就正常了。
我现在准备恢复到5.4内核了。

[ruichen-git]

试试这个 commit ( AmadeusGhost@2e74f09) 能不能解决问题

不知道怎么去抓你这个commit去编译，git玩的不熟 ^_^

[blueveryday]

pppoe报错rename，然后拨号链接显示连上的，但是网络实际是断了，MAN口的iptv还可以使用。

[Ljzkirito]

试试这个 commit ( AmadeusGhost@2e74f09) 能不能解决问题

昨天git clone --depth 1 https://github.com/AmadeusGhost/lede -b modified openwrt编译
今天不保留配置升级，仍然出现PPPoE显示连上，但网络实际断连的情况

[Ljzkirito]

试试 https://github.com/AmadeusGhost/lede/tree/ramips ，另外就是在 AmadeusGhost@34d9c51 上把小娱 C5 的有线驱动改成 4.14 上的了（可以开 hwnat 了）。

开机一小时，PPPoE网络连接正常，未发现断网。

HC5962的这个问题能不能一并解决一下？同样存在相同的问题。

[Ljzkirito]

HC5962也是mt7621设备吧，是的话此pr应该一并修复了

对，就是mt7621的，现在再用5.4的内核。

[Ljzkirito]

对，就是mt7621的，现在再用5.4的内核。

此pr是针对mediatek芯片修复的，HC5962也已经修复了，等待合并即可

[blueveryday]

即

合并了我测试一哈。

[Myoko]

有没有试过4.19.138 内核？

[Ljzkirito]

有没有试过4.19.138 内核？

没有试过，也不知道怎么更换lean的内核版本

[Myoko]

有没有试过4.19.138 内核？

没有试过，也不知道怎么更换lean的内核版本

云端编一个试试看！

所以怎么编译4.19.138 内核的版本？不是编程出身的，不会呀。😂
或者你的意思是用 https://github.com/coolsnowwolf/openwrt.git 编一个吗？

看P3TERXActions-OpenWrt中文教程，才会的Fork
Revert是用GitHub Desktop做的😂，也不会git命令😂

[Myoko]

看P3TERXActions-OpenWrt

用P3TERX的Actions-OpenWrt 在云端编译就可以了！

[Myoko]

有没有试过4.19.138 内核？

ramips 只有 4.14 和 5.4，而且驱动都同步官方了，回去意义不大

ramips 那就没办法了！

重新编译，刷了，问题依旧。
我的网络：HC5962+wan+man(iptv)，单线复用。
故障复现：
上网正常，收视IPTV组播，一切正常，用了半个小时。
然后关掉IPTV播放器，路由器就断网了，wan口显示获取的pppoe拨号信息正常，但是整个网络不能上网了。
log没有错误信息。保持上面1095.783329的内核记录不变。
虽然不能上网了，IPTV可以正常使用。
WAN口跃点是1，MAN口跃点是100
问题原因不明。

目前回退到commit 0ecfa0d4fa08c72595dae904f8f326e5ad94fb89编译的固件，安装上面的操作，使用一切正常。
并且内核日志没有renamed的报错，截取如下：
