【标题描述】[20.03-LTS-SP1] [aarch64]在鲲鹏台式机测试LTP用例的时候,kernel 死锁,系统卡死,无法操作。 【环境信息】 硬件信息:鲲鹏台式机 cpu: ``` [root@ltptest crash]# lscpu 架构: aarch64 CPU 运行模式: 64-bit 字节序: Little Endian CPU: 8 在线 CPU 列表: 0-7 每个核的线程数: 1 每个座的核数: 8 座: 1 NUMA 节点: 1 厂商 ID: HiSilicon 型号: 0 型号名称: Kunpeng-920 步进: 0x1 CPU 最大 MHz: 2600.0000 CPU 最小 MHz: 200.0000 BogoMIPS: 200.00 L1d 缓存: 512 KiB L1i 缓存: 512 KiB L2 缓存: 4 MiB L3 缓存: 32 MiB NUMA 节点0 CPU: 0-7 Vulnerability Itlb multihit: Not affected Vulnerability L1tf: Not affected Vulnerability Mds: Not affected Vulnerability Meltdown: Not affected Vulnerability Spec store bypass: Not affected Vulnerability Spectre v1: Mitigation; __user pointer sanitization Vulnerability Spectre v2: Not affected Vulnerability Srbds: Not affected Vulnerability Tsx async abort: Not affected 标记: fp asimd evtstrm aes pmull sha1 sha2 crc32 atomics fphp asimdhp cpuid asimdrdm jscvt fcma d cpop asimddp asimdfhm ``` 软件信息: OS:openeuler-20.03-sp1 kernel version: ``` [root@ltptest pstore]# uname -r 4.19.90-2102.3.0.0058.up2.uel20.aarch64 ``` 【问题复现步骤】 1. 下载 20210121 版本 ltp 源码 ltp-full-20210121.tar.bz2 。根据readme 执行编译安装 ``` yum install gcc git make pkgconf autoconf automake bison flex m4 kernel-headers glibc-headers psmisc # 设置英文环境 export LANG="en_US.UTF-8" export LC_ALL="en_US.UTF-8" # 设置 hostname,下面设置了ltptest。设置其他hostname,也可以,但是要求为全英文。这样可以避免系统软件的一些解析问题。 hostnamectl set-hostname ltptest make autotools ./configure make make install ``` 2. 执行 ltp 测试 ``` cd /opt/ltp nohup ./runltp >$$.log 2>&1 & ``` 【预期结果】 ltp 测试完成,无失败项,允许跳过项。测试完成之后操作系统可正常使用。 【实际结果】 ltp测试过程中,系统卡死。鼠标键盘都无响应。显示器报错如下 message 无额外日志,/var/crash 无vmcore生成  【附件信息】 比如系统message日志/组件日志、dump信息、图片等
