RTL8111 网卡IRQ高，CPU负载大，系统卡顿 #10394

Closed wd2es7 closed 1 year ago

wd2es7 commented 1 year ago

具体问题

  1. 固件为[openwrt-x64-R22.10.1-squashfs-combined-efi.img.gz]
  2. 运行2-10小时后出现带宽降低，CPU负载高的情况
  3. 其中网卡的IRQ很高
  4. 刷回 [openwrt-R20.4.8-x64-combined-squashfs.1.rar] 后一切正常；本人观察到该固件使用的是RTL8169驱动

(2) 路由器型号和固件版本

A：路由器为N3710的软路由，4口RTL8111的千兆接口

个人猜测可能是“启用 RTL 鸡血驱动（ RTL81xx 和 RTL8125系列）”导致的问题

求解，谢谢各位

我的还是去年五月的最好用，呵呵

没遇到此类情况，建议说明“网卡IRQ高，CPU负载大”的时候在跑什么应用

openclash DDNS Docker - Alist

这三个全部关掉依然可以复现问题
