1) run the schuduling jitter test but printk the results to the console instead of writing them to the rt-FIFO and include the absolute min/max since begin of the test-run (not only min/max of the ntests of the curent loop). 2) login at the linux console and type "halt" this way linux will shut down and the rtlinux thread will happily continue to write min/max to the console (you can't log it to a file though). So in this setup you have eliminated all of posible linux/X/whatever iritations that could be comming in and will see only the hardware induced jitter. hofrat -- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl <Your_email>" | mail [EMAIL PROTECTED] -- For more information on Real-Time Linux see: http://www.rtlinux.org/
