Description Jakub Jasinski 2006-09-10 00:01:14 UTC
Most recent kernel where this bug did not occur:
Distribution: Fedora Core 5
Hardware Environment: Compaq Presario 5201CA
Software Environment: bash
Problem Description:

Fan cannot be controlled.  In other words, directory /proc/acpi/fan is 
empty.

Steps to reproduce:

ls /proc/acpi/fan
Comment 1 Konstantin Karasyov 2006-09-11 08:21:29 UTC
Please, submit the 'dmesg' and 'acpidump' commands output.
Comment 2 Konstantin Karasyov 2006-09-12 01:54:10 UTC
Fan device (i.e. device with HID 'PNP0C0B') doesn't defined in this system's 
DSDT, as well as device list for active cooling (object '_AL0'), so fan control 
via ACPI functionality isn't possible.
