Why this is so is still unclear, but since the other problem I had was due to the kernel reducing the max sample_freq, I tried: [root@ssdandy ~]# echo 10000 > /proc/sys/kernel/perf_event_max_sample_rate [root@ssdandy ~]# perf test 21 21: Test object code reading : Ok [root@ssdandy ~]# echo 7000 > /proc/sys/kernel/perf_event_max_sample_rate [root@ssdandy ~]# perf test 21 21: Test object code reading : FAILED!
