1.关于你要提交的问题

新款R2S （11月出厂后大孔指示灯版本）内核奔溃重启

Q：是否搜索了issue (使用 "x" 选择)

[x ] 没有类似的issue

2. 详细叙述

最近购买的R2S大概是11月份出厂的，板子貌似有些变化，最直接的变化就是指示灯孔变大，旧款还是小孔的指示灯在 https://github.com/coolsnowwolf/lede/commit/a8ddfc2e1025e2f35099b8757c7cf581cc87716b 此版本编译出来的固件刷入后大约运行1小时左右开始内核奔溃并且自动重启或流量大CPU大约满载时内核奔溃重启然而旧版R2S（小孔指示灯版本）没有这个问题从拿货渠道打听到友善订了1W片新的板子，并且设计上有些改变，最直观的就是指示灯变大孔

(1) 具体问题

A：

大约运行1小时左右内核奔溃并且自动重启大约运行1小时左右内核奔溃死机流量大时内核奔溃重启流量大时内核奔溃死机 CPU满载时内核奔溃重启

(2) 路由器型号和固件版本

A：

R2S新款11月份出厂后版本（指示灯大孔版本）编译版本 https://github.com/coolsnowwolf/lede/commit/a8ddfc2e1025e2f35099b8757c7cf581cc87716b

超频后不稳定了

kxdn3 commented 10 months ago

U不行

超频后不稳定了

没有超频

chobitsos commented 10 months ago

U不行

但是旧款没有这个问题

初步怀疑新的设计可能需要更高的 CPU 电压 #3f6bb72ee84d8730155669b484e9dad828832951 提交了个 patch 拉高0.05v 电压，你试试

还是不行，貌似更严重了，随便打开个测速网站内核就奔了，流量稍微大一丢丢就内核奔溃重启了都不带死机的，直接重启了打开抖音不停的刷视频10个内必内核奔溃重启😂😂 不知道会不会是更换了板载闪存频率或者动了那一部分的板子逻辑导致，官方sdk也没更新什么😳

另外，实时输出日志有两个地方奔溃的地方貌似都跟CPU有关

CPU: 3 PID: 2167 Comm: ssr-redir Tainted: G        W         5.15.136 #0
WARNING: CPU: 3 PID: 2167 at net/ipv4/tcp_input.c:2981 tcp_fastretrans_alert+0x600/0x920

只要打开fast.com测速就能触发上面的奔溃信息，好像是ssr-redir一占用CPU就挂，当然我也测试其他占用CPU的软件比如跑分软件，也是同样内核奔溃，看来奔溃都有个共同点就是一占用CPU就挂
