The tests are not able to mount on /dev/cpuctl which is causing cpu controller testing, latency tests, and cpuctl_test_fj to fail, seems to be only on g1-small instances. This error has been observed in previous cycles and is not a new regression. 20:09:23 DEBUG| [stdout] startup='Mon Sep 13 20:07:02 2021' 20:09:23 DEBUG| [stdout] TEST 1: CPU CONTROLLER TESTING 20:09:23 DEBUG| [stdout] RUNNING SETUP..... 20:09:23 DEBUG| [stdout] ERROR: Could not mount cgroup filesystem on /dev/cpuctl..Exiting test 20:09:23 DEBUG| [stdout] Cleanup called 20:09:23 DEBUG| [stdout] cat: /dev/cpuctl/group_def/tasks: No such file or directory 20:09:23 DEBUG| [stdout] TEST 3: CPU CONTROLLER TESTING 20:09:23 DEBUG| [stdout] RUNNING SETUP..... 20:09:23 DEBUG| [stdout] ERROR: Could not mount cgroup filesystem on /dev/cpuctl..Exiting test 20:09:23 DEBUG| [stdout] Cleanup called 20:09:23 DEBUG| [stdout] cat: /dev/cpuctl/group_def/tasks: No such file or directory 20:09:23 DEBUG| [stdout] TEST 4: CPU CONTROLLER TESTING 20:09:23 DEBUG| [stdout] RUNNING SETUP..... 20:09:23 DEBUG| [stdout] ERROR: Could not mount cgroup filesystem on /dev/cpuctl..Exiting test 20:09:23 DEBUG| [stdout] Cleanup called 20:09:23 DEBUG| [stdout] cat: /dev/cpuctl/group_def/tasks: No such file or directory 20:09:23 DEBUG| [stdout] TEST 5: CPU CONTROLLER TESTING 20:09:23 DEBUG| [stdout] RUNNING SETUP..... 20:09:23 DEBUG| [stdout] ERROR: Could not mount cgroup filesystem on /dev/cpuctl..Exiting test 20:09:23 DEBUG| [stdout] Cleanup called 20:09:23 DEBUG| [stdout] cat: /dev/cpuctl/group_def/tasks: No such file or directory 20:09:23 DEBUG| [stdout] /opt/ltp/testcases/bin/run_cpuctl_stress_test.sh: line 97: /opt/ltp/output/cpuctl_results_stress-678.txt: No such file or directory 20:09:23 DEBUG| [stdout] TEST 6: CPU CONTROLLER STRESS TESTING 20:09:23 DEBUG| [stdout] RUNNING SETUP..... 20:09:23 DEBUG| [stdout] ERROR: Could not mount cgroup filesystem on /dev/cpuctl..Exiting test 20:09:23 DEBUG| [stdout] Cleanup called 20:09:23 DEBUG| [stdout] cat: /dev/cpuctl/group_def/tasks: No such file or directory 20:09:23 DEBUG| [stdout] TEST 7: CPU CONTROLLER STRESS TESTING 20:09:23 DEBUG| [stdout] RUNNING SETUP..... 20:09:23 DEBUG| [stdout] ERROR: Could not mount cgroup filesystem on /dev/cpuctl..Exiting test 20:09:23 DEBUG| [stdout] Cleanup called 20:09:23 DEBUG| [stdout] cat: /dev/cpuctl/group_def/tasks: No such file or directory 20:09:23 DEBUG| [stdout] TEST 8: CPU CONTROLLER STRESS TESTING 20:09:23 DEBUG| [stdout] RUNNING SETUP..... 20:09:23 DEBUG| [stdout] ERROR: Could not mount cgroup filesystem on /dev/cpuctl..Exiting test 20:09:23 DEBUG| [stdout] Cleanup called 20:09:23 DEBUG| [stdout] cat: /dev/cpuctl/group_def/tasks: No such file or directory 20:09:23 DEBUG| [stdout] /opt/ltp/testcases/bin/run_cpuctl_stress_test.sh: line 120: /opt/ltp/output/cpuctl_results_stress-9.txt: No such file or directory 20:09:23 DEBUG| [stdout] TEST 9: CPU CONTROLLER STRESS TESTING 20:09:23 DEBUG| [stdout] RUNNING SETUP..... 20:09:23 DEBUG| [stdout] ERROR: Could not mount cgroup filesystem on /dev/cpuctl..Exiting test 20:09:23 DEBUG| [stdout] Cleanup called 20:09:23 DEBUG| [stdout] cat: /dev/cpuctl/group_def/tasks: No such file or directory 20:09:23 DEBUG| [stdout] /opt/ltp/testcases/bin/run_cpuctl_stress_test.sh: line 127: /opt/ltp/output/cpuctl_results_stress-10.txt: No such file or directory 20:09:23 DEBUG| [stdout] TEST 10: CPU CONTROLLER STRESS TESTING 20:09:23 DEBUG| [stdout] RUNNING SETUP..... 20:09:23 DEBUG| [stdout] ERROR: Could not mount cgroup filesystem on /dev/cpuctl..Exiting test 20:09:23 DEBUG| [stdout] Cleanup called 20:09:23 DEBUG| [stdout] cat: /dev/cpuctl/group_def/tasks: No such file or directory 20:09:23 DEBUG| [stdout] TINFO Running cpuctl Latency Test 1 20:09:23 DEBUG| [stdout] TINFO The latency check task started 20:09:23 DEBUG| [stdout] FAIL The Latency test 1 failed 20:09:23 DEBUG| [stdout] Max latency observed = 123838 in Iteration 0 20:09:23 DEBUG| [stdout] The results FAIL is just intuitive and not exact failure.
