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
Please, submit the 'dmesg' and 'acpidump' commands output.
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.
