For example, driving it with pwm=2 I get speeds over 50K rpms, while of course the fan is stopped (almost?). This could be just an hardware sensitivity problem in the sensor chip, or a false measure triggered by fan vibration, but maybe you know better. /Simone -- http://thisurlenablesemailtogetthroughoverzealousspamfilters.org - 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/
