Results from Linaro’s test farm. Regressions detected on arm and arm64 (Juno-r2) We are bisecting this problem and get back to you soon.
perf test cases failed perf: * Track-with-sched_switch * perf_record_test * perf_report_test
Bad case: [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.002 MB perf-lava-test.data ]
when it was pass it prints number of samples like below, Good case: [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.004 MB perf-lava-test.data (46 samples) ]
steps to reproduce: # perf record -e cycles -o perf-lava-test.data ls -a 2>&1 | tee perf-record.log

Any hint by bisection as to what this problem is caused by?
