I investigated this now. The problem is that the event is listed, but cannot be set up. I saw it also with 'data_writes' on another system.
That's a generic problem, the test just exposes it. It's a side effect of the fragile kernel->user interface in perf and likely hard to fix.
The only thing I can do is to ignore failures here and only print messages.
