Ok, I'm already running function tracer.
I did the following:
echo ftrace > /debug/tracing/current_tracer
echo print-parent > /debug/tracing/iter_ctrl
Is it enough to get what you suggest?
If so, I'll leave it enabled:
echo 1 > /debug/tracing/tracing_enabled
and stop and get the data just when the problem happens... then
I should know what I should grep, what's relevant.
thank you again.
