--- Comment #10 from Nicholas Kazlauskas (nicholas.kazlauskas at amd.com) ---
I don't expect the trace log to be completely empty.

You'll need to leave the trace log running after enabling it as well (with
tracing on/trace).

You'll also need various config options set in your kernel:

CONFIG_FUNCTION_TRACER
CONFIG_FUNCTION_GRAPH_TRACER
CONFIG_STACK_TRACER
CONFIG_DYNAMIC_FTRACE

Sorry if this is a little bit involved, but I'd like capture the exact sequence
of atomic commits with the trace so I can reproduce the sequence on my end.

Thanks!
