The hash one that you reported? That is something with the function tracer. Are you able to enable function tracing as non-root? Or is it because you gave more permissions for non-root to use extra perf commands. Because no one but root should be able to enable function tracing, as that can add a large overhead to the system. -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
