Hi Jean, > For fan regulation, I'd hope that the ACPI thermal zone and fan setup > would provide what you need in a more efficient way. As a side note, > ACPI might be accessing the chip concurently. That might explain the > problems you observed. Unfortunately all ACPI provides in fan & thermal zone is nil... Thus my use of lm_sensors. Do you have any pointers as to fan control? Something must be controlling it? Regards, Morgan. -- Morgan Read <mailto:mstuffATplDOTnet>
