thank you for this tip. i'm now using this. > Thanks for giving this a try. Please let me know how it goes. Ok, i've created a cron job that builds emovix every 30mins. I've tested that it provokes a switch from 1.001GHz 1.1V to 1.8GHz 1.5V. So far, 10 switches have occured, still no problem. I'll let it go at least a day and come back to you. -Pascal PS: Does the machine freeze upon failure? i don't have physical access to the box until i go back to montreal (on the 10th). -- XBGM# (http://xbgm.sf.net) MoviXMaker-2 (http://sv.gnu.org/projects/movixmaker) [e]MoviX[2] (http://movix.sf.net) Debian GNU/Linux (http://www.debian.org)
