is there something specific to my config that causes this to happen? I
assume other folks are running the function_graph selftest under other,
quite possibly more sane, configs without running into it ... or is it
just something that most folks aren't running (i can't remember why i
turned ftrace selftests on, other than, perhaps, general curiosity) ...
you don't run into this under your "normal" configs?
