hm, thats the unique sample_type issue again ;) Once we set

Sorry, I don't understand why we need to set it for all events. Just
setting it for a group is not sufficient? Please shed some light on
this.
perf does not support multiple sample_types -- all events in the session
need to use the same one.
Can I ask why? :)
