Description of problem:
Tone平台中执行kernel-selftests测试套，测试机器死机；手动执行breakpoints:step_after_suspend_test用例机器死机

软件环境：
#内核版本：
# uname -r
5.10.134-16.2_rc1.an23.loongarch64

#系统版本
# cat /etc/os-release 
NAME="Anolis OS"

#安装源配置
source源配置
http://build.openanolis.cn/kojifiles/output/anolis-23-20240124.9/compose/os/source/tree/

Steps to Reproduce:
1.配置yum源，enable source源，获取source源中的内核源码的rpm包
2.rpm -ivh kernel-5.10.134-16.2_rc2.an23.src.rpm
3.解压源码
cd rpmbuild/SOURCES/
tar xf linux-5.10.134-16.2_rc2.an23.tar.xz
cd linux-5.10.134-16.2_rc2.an23/tools/testing/selftests/
4.安装依赖
./kselftest_deps.sh -p gcc
./kselftest_install.sh
cd kselftest_install
5.执行用例
./run_kselftest.sh -t breakpoints:step_after_suspend_test

Actual results:
测试死机

Expected results:
测试通过，机器不死机无异常
