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.
