thank you for this tip. i'm now using this.

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.

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).
