Thanks for reporting. I could reproduce it. To narrow this down, I tried to run the below command [tracing]# for i in events/*/*/enable ; do echo $i; echo 1 > $i; done And it ran through the end without any problem. Hm, next I checked the difference of available_events and set_event. [tracing]# diff available_events set_event 283d282 < ftrace:function So, I guess it was caused by enabling ftrace:function, and it is unable to do that via set_event, nor events/ftrace/enable I'm not sure how, but it seems that ftrace:function can be enabled by the events/enable.
