If you have an ssh login on any other local box (and have ssh autologin enabled), then there's a good way to script this: time ssh otherbox "time ssh thisbox \"sleep 10\"" this way you'll get two time measurements of the same timeout, one on the other box (which shouldnt be running the buggy kernel :-), one on this box, while the timer runs on this box. Here it gives: earth3:~> time ssh pluto "time ssh earth3 \"sleep 10\"" real 0m10.141s user 0m0.012s sys 0m0.008s real 0m10.278s user 0m0.024s sys 0m0.004s Ingo - 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/
