Good point.
I found the culprit:
[ 0.560002] event_trace_enable: �GT����� call ffffffff81613930 (core)
[ 0.564001] event_trace_enable: �GTȁ���� call ffffffff816139c0 (core)
compudj@ok:~/git/rostedt/linux-trace$ objdump -t vmlinux |grep ffffffff81613930
ffffffff81613930 l O .data 0000000000000090 event_sys_exit
compudj@ok:~/git/rostedt/linux-trace$ objdump -t vmlinux |grep ffffffff816139c0
ffffffff816139c0 l O .data 0000000000000090 event_sys_enter
I'll look into those two sites tomorrow morning.
Thanks,
Mathieu
