    What does perf --version show?

I'm not sure what version that hash is. I'm using perf version
3.0.22. Is my version that too old?

That's a commit id for perf-stat to discriminate unsupported events from 

not counted events.

It was committed around 3.0 timeframe. Try compiling a newer version of 

perf and see if it addresses your concern.
