软件信息
- OS版本及分支信息
- 内核信息
- 发现问题的组件版本信息
网络信息
- 如果有特殊组网，请提供网络拓扑信息

**【问题复现步骤】**，请描述具体的操作步骤
1、在loongarch架构下，创建虚拟机
2、在虚拟机下搭建ltp测试环境
    下载ltp源代码
    git clone https://github.com/linux-test-project/ltp.git
    设置指定标签 
    git reset --hard 3ebc2dfa85c2445bb68d8c0d66e33c4da1e1b3a7
    编译ltp
    make autotools
    ./configure
    make
    make install
3、运行ltp测试
    cd /opt/ltp
    ./runltp
**【实际结果】**，请描述出问题的结果和影响
测试结果如下:
发现虚拟机报rcu超时
