[问题简述] Anolis8.6 ck-41.9 aarch64，内部版的alitests nightly产生， alitests测试套spec_c2c_test01用例长时间（4h）无法结束，messages日志未发现异常信息，/var/crash也没有vmcare异常触发 [复现步骤] 1 安装待测的nightly kernel相关包 2 检查环境是否可以正常手工触发vmcare 3 git clone git@gitlab.alibaba-inc.com:alikernel/ltp.git export BUILD_ALITESTS_ONLY=yes export CFLAGS="${CFLAGS} -fcommon" make autotools ./configure make && make install cd /opt/ltp ./runltp -f alitests -s spec_c2c_test01 [环境信息] [root@l57h15217 ~]# uname -r 4.19.91-542.git.631dd32a8.an8.aarch64 [root@l57h15217 ~]# cat /etc/redhat-release Anolis OS release 8.6 [root@l57h15217 ~]# cat /proc/cmdline BOOT_IMAGE=(hd1,gpt2)/boot/vmlinuz-4.19.91-542.git.631dd32a8.an8.aarch64 root=UUID=886214fc-8735-4e91-927d-bed20ed486bb ro console=tty0 console=ttyS0,115200 rd.driver.pre=ahci slub_debug=FPZU kmemleak=on crashkernel=0M-2G:0M,2G-8G:192M,8G-:256M [root@l57h15217 ~]# df -h Filesystem Size Used Avail Use% Mounted on devtmpfs 378G 0 378G 0% /dev tmpfs 378G 128K 378G 1% /dev/shm tmpfs 378G 19M 378G 1% /run tmpfs 378G 0 378G 0% /sys/fs/cgroup /dev/sda2 49G 18G 29G 39% / /dev/sda1 1022M 6.7M 1016M 1% /boot/efi tmpfs 76G 0 76G 0% /run/user/0 [root@l57h15217 ~]# free -g total used free shared buff/cache available Mem: 755 61 692 0 1 690 Swap: 1 0 1 [root@l57h15217 ~]# lscpu Architecture: aarch64 Byte Order: Little Endian CPU(s): 96 On-line CPU(s) list: 0-95 Thread(s) per core: 1 Core(s) per socket: 48 Socket(s): 2 NUMA node(s): 1 Vendor ID: HiSilicon BIOS Vendor ID: HiSilicon Model: 0 Model name: Kunpeng-920 BIOS Model name: HUAWEI Kunpeng 920 5250 Stepping: 0x1 CPU max MHz: 2600.0000 CPU min MHz: 200.0000 BogoMIPS: 200.00 L1d cache: 64K L1i cache: 64K L2 cache: 512K L3 cache: 24576K NUMA node0 CPU(s): 0-95 Flags: fp asimd evtstrm aes pmull sha1 sha2 crc32 atomics fphp asimdhp cpuid asimdrdm jscvt fcma dcpop asimddp asimdfhm [期望结果] case可以正常运行 [实际结果] case长时间不结束
