SSH登陆小米路由器卡死

root用户登陆小米路由器之后整个应用都卡死了
目前已知的小米路由器上的是dropbear

Start by reproducing an SSH login as root to the Xiaomi router, noting that it uses Dropbear. Check whether the entire application freezes during or after login, and gather the client version and relevant logs. Done means the session no longer hangs the application, with a regression test or documented reproduction if the project supports one.
