RK3588+RTLinux内核，在ubuntu下死机

[北城半夏yi]

  题主使用内核版本为5.10.110，打上了RT对应版本的patch，编译没有报问题，烧录进RK3588也成功了，启动时显示的内核版本也有RT的标签，进入系统后使用串口登录到终端中也挺正常（由于RT与桌面GUI兼容性不好，所以题主使用命令将桌面关闭了），然后在终端中等待一会或者使用sudo权限执行一些命令时内核会直接卡死，因为题主想使用rt-test来测试linux的实时性，运行测试命令时出现的此现象，后来发现进入终端后，过一阵也会有此现象，求帮忙分析一波，日志如下，此部分有很多重复日志，这里只放出不重复的部分：
