【复现步骤】
#内核包：
http://8.131.87.1/kojifiles/repos/dist-an23.3-riscv64-gcc14-build/latest/riscv64/toplink/work/tasks/5939/1035939/
#获取ltp源码并编译
git clone http://code.alibaba-inc.com/alikernel/ltp.git --branch Ali6000
export CFLAGS="-fcommon"  
cd ltp
make autotools
make
make install
cd /opt/ltp
#执行用例
./runltp -f cpuhotplug -s  cpuhotplug04

【实际结果】ltp cpuhotplug04 用例运行存在fail，且卡住长时间无法运行完成
【预期结果】ltp cpuhotplug04  用例运行pass
