电犀牛R66S使用本固件时有时无法识别第二个RTL8125网卡

[jysqice]

电犀牛R66s 2G版
Linux armbian 6.1.10-flippy-81+

问题如题目，出现问题时dmesg和lspci均没有0002:21:00.0的网卡信息，经过数千次重启测试，发现CPU温度低于40度时容易出现，CPU高于50度时完全不出现。使用“出厂固件”时无此问题

我的猜测：cpu的温控机制使得低温时运算速度过快，扫描pcie设备时未等到pcie设备响应即结束而导致了该问题出现
如果以上猜测属实，那么增加pcie扫描延时或者调整cpu温控机制均可以解决该问题

你指的第二个网卡，是外壳上标注为LAN的还是WAN的？

[jysqice]

WAN

我测试下

想要使问题重现，可以用风扇对着吹

不用风扇基本正常

放在rc.local里的自动测试脚本，如要中止测试插入一个U盘即可

33度，大风扇吹一个晚上试试。

[jysqice]

测试需要反复重启，启动后网卡数量不会变，既不会减少也不会增加，缺失网卡情况下rescan仍然无效，不缺情况下再冷也是两个

[kuaner]

不确定与温度是否有关，我也有这个情况，openwrt固件，r68s，eth2不见了，通过ip link 看不到eth2

[kuaner]

[kuaner]

我是openwrt的固件，cpu的模式是schedutil，依然有这个问题，eth2不见了

[jysqice]

ayufan-rock64/linux-mainline-kernel@b5ce971
一个可能是类似问题的解决方案

[kuaner]

回退到79正常，80，81都有这个情况

[ophub]

r66s放在风扇上吹了16个小时，一直保持在30多度，现在WAN口网络正常
