--- Comment #4 from Alexandre Demers alexandre.f.demers@gmail.com --- Definitively something about sclk or mclk and the voltages, but I haven't had the time to dig deeper for now. I've added some printk to be sure everything was being maxed as supposed. Could it be a combo between freq and voltage?
