It does that with many older versions of the perf as well on 3.14. It runs fine with newt mode. Works fine with my 3.11 kernel. So something must be broken with 3.14. Can you reproduce the problem as well? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
