My specific CPU (i7-4790K @ 4.00GHz) unfortunately seems to have
limited "Frontend" support. E.g. 

 # perf record -g -a -e stalled-cycles-frontend
 Error:
 The stalled-cycles-frontend event is not supported.

And AFAIK icache misses are part of "frontend".

Ignore stalled-cycles-frontend. It is very unreliable and has never worked right.
toplev gives you much more reliable output.
