Description of problem: 发生hardlock 导致机器重启,使用ltp20230929测试内核devel-4.19 和release-4.19 , 在海光7185的cpu型号上,单独测试shmctl05出现。 Version-Release number of selected component (if applicable): How reproducible: 海光7185的cpu Steps to Reproduce: 1.安装ltp-20230929 2.进入ltp目录 3.执行测试命令./runltp -s shmctl05 -I 10 Actual results: <<<test_start>>> tag=5_ITERATION_shmctl05 stime=1701400505 cmdline="shmctl05" contacts="" analysis=exit <<<test_output>>> tst_test.c:1690: TINFO: LTP version: 20230929 tst_test.c:1576: TINFO: Timeout per run is 0h 00m 40s ../../../../../include/tst_fuzzy_sync.h:484: TINFO: Minimum sampling period ended ../../../../../include/tst_fuzzy_sync.h:308: TINFO: loop = 1024, delay_bias = 0 ../../../../../include/tst_fuzzy_sync.h:297: TINFO: start_a - start_b: { avg = 12ns, avg_dev = 8ns, dev_ratio = 0.73 } ../../../../../include/tst_fuzzy_sync.h:297: TINFO: end_a - start_a : { avg = 4935ns, avg_dev = 112ns, dev_ratio = 0.02 } ../../../../../include/tst_fuzzy_sync.h:297: TINFO: end_b - start_b : { avg = 3153ns, avg_dev = 123ns, dev_ratio = 0.04 } ../../../../../include/tst_fuzzy_sync.h:297: TINFO: end_a - end_b : { avg = 1794ns, avg_dev = 70ns, dev_ratio = 0.04 } ../../../../../include/tst_fuzzy_sync.h:297: TINFO: spins : { avg = 622 , avg_dev = 31 , dev_ratio = 0.05 } ../../../../../include/tst_fuzzy_sync.h:496: TINFO: Reached deviation ratios < 0.10, introducing randomness ../../../../../include/tst_fuzzy_sync.h:499: TINFO: Delay range is [-1071, 1731] ../../../../../include/tst_fuzzy_sync.h:308: TINFO: loop = 1385, delay_bias = 0 ../../../../../include/tst_fuzzy_sync.h:297: TINFO: start_a - start_b: { avg = 20ns, avg_dev = 2ns, dev_ratio = 0.08 } ../../../../../include/tst_fuzzy_sync.h:297: TINFO: end_a - start_a : { avg = 4968ns, avg_dev = 217ns, dev_ratio = 0.04 } ../../../../../include/tst_fuzzy_sync.h:297: TINFO: end_b - start_b : { avg = 3076ns, avg_dev = 132ns, dev_ratio = 0.04 } ../../../../../include/tst_fuzzy_sync.h:297: TINFO: end_a - end_b : { avg = 1913ns, avg_dev = 122ns, dev_ratio = 0.06 } ../../../../../include/tst_fuzzy_sync.h:297: TINFO: spins : { avg = 667 , avg_dev = 50 , dev_ratio = 0.08 } client_loop: send disconnect: Broken pipe Expected results: 正常测试结束 Additional info:
