I have experienced quite some problems with ACPI om my ASUS L8400. I think the root of the problem has with heat to do, it behaves really wierd when the CPU load is high and the CPU becomes hot. The temperature thresholds change repeatedly, all of a sudden lm_sensors say the alloed interval is between 0 and -99, and the temperature is 0, which makes the fan shutdown. Then it might throttle down to cool down, all of a sudden the temperature scale has changed anew and the temperature alarm goes off. Sometimes this starts the fan, sometimes it shuts down. With APM enabled I only notice jerky performance, the whole system appears to freeze every now and then, but it doesn't shut down, the sensor values remain sensible and the fan runs all the time as long as the machine is hot. The drawback is that the clock drags severely during things like huge emerges and such. /Rasmus Wiman http://rasmus.wiman.org http://dagbok.wiman.org I program my home computer Beam myself into the future -- [EMAIL PROTECTED] mailing list
