1.关于你要提交的问题

Q：是否搜索了issue (使用 "x" 选择)

• [ x] 没有类似的issue

2. 详细叙述

(1) 具体问题

A：最新源码编译的easymesh，mt7621的cr660x开启后内核会报错，但是mt7620的没事，是不是跟dsa驱动有关呢。。

(2) 路由器型号和固件版本

A：mt7621的小米cx660x开启会报错， mt7620的小米3不会报错。 batman-adv的版本试过2021.4和2021.3的多个版本，都会报错。。

用1.8版本的加上2021.3的batman-adv就正常了，但是链接的速率不是很高。 866的5g连的mesh，信号强度45%左右，速度就75Mbs， wifi6的1200的速率互联，45%的信号强度，实际mesh速度就100M的样子。 还是用有线吧。

两个路由器放一起，距离不到10cm， 866的路由器互联，信号强度100%， 100M的带宽，mesh后在子路由测速只有70出头。。只有这利用率了吗。。
