Yes, /proc/acpi/fan/... should be present, also in 2.4.x kernels; I had it all the time since 2.4.18+acpi-20020329 (the first Linux+ACPI kernel I put on my then brandnew Gericom M6-T laptop). I haven't tried kernel 2.4.20-rc1 yet, though. Are you using the ACPI patch from http://sf.net/projects/acpi?
Yes. With the suggested debugging-patch _HIGH -> _LOW and with acpi-debugging enabled.
Of course the fan can only be controlled through ACPI if there is a fan and it is listed correctly in the ACPI description tables. This is typically the case for laptops and notebooks (but not for all of them), and typically not the case for desktop machines.
It's a Acer Travelmate Notebook and it has got a fan. I'm afraid, that I am not able to have a look to the ACPI-description table with my recent knowlege. How could I check this? (According to lsmod the fan-module is loaded.) Gerfried ------------------------------------------------------- This sf.net email is sponsored by: See the NEW Palm Tungsten T handheld.
