I am running perf stat to count hardware counters but am confused about stall

On running the command perf stat ./progname, I am told that stalled-cycles-
frontend and stalled-cycles-backend are not counted, but when on running perf
stat -v ./progname, I am told that stall cycles are not supported by the kernel.
So which is it?

What does perf --version show?

Should be fixed by 2cee77c4505fc581f41b44e18ffc0953b67a414c.
