I'm working on getting acpi working correctly on my latitude C600. All events work correctly, but the fan does not automaticaly come on when the processor gets hot. ( Luckily I have the i8k module and i8kutils working, so I haven't melted my processor yet. and then the bios handles the fan alright when I use apm, too. ) Can anyone tell me what i may have broke? When i jave PNPACPI enabled i get this: brian@grace ~ $ sudo modprobe thermal WARNING: Error inserting processor (/lib/modules/2.6.16-gentoo-r6/kernel/drivers/acpi/processor.ko): Invalid module format I found this in my dmesg: processor: exports duplicate symbol acpi_processor_set_thermal_limit (owned by kernel) I have the kernel ( 2.6.16-gentoo-r6) configured like this: brian@grace /usr/src/linux $ cat .config | grep ACPI # Power management options (ACPI, APM) # ACPI (Advanced Configuration and Power Interface) Support CONFIG_ACPI=y CONFIG_ACPI_SLEEP=y CONFIG_ACPI_SLEEP_PROC_FS=y # CONFIG_ACPI_SLEEP_PROC_SLEEP is not set CONFIG_ACPI_AC=y CONFIG_ACPI_BATTERY=y CONFIG_ACPI_BUTTON=m CONFIG_ACPI_VIDEO=m # CONFIG_ACPI_HOTKEY is not set CONFIG_ACPI_FAN=m CONFIG_ACPI_PROCESSOR=m CONFIG_ACPI_THERMAL=m # CONFIG_ACPI_ASUS is not set # CONFIG_ACPI_IBM is not set # CONFIG_ACPI_TOSHIBA is not set CONFIG_ACPI_BLACKLIST_YEAR=0 # CONFIG_ACPI_DEBUG is not set CONFIG_ACPI_EC=y CONFIG_ACPI_POWER=y CONFIG_ACPI_SYSTEM=y # CONFIG_ACPI_CONTAINER is not set CONFIG_X86_ACPI_CPUFREQ=m # CONFIG_X86_ACPI_CPUFREQ_PROC_INTF is not set CONFIG_PNPACPI=y # CONFIG_SERIAL_8250_ACPI is not set also i noticed that when i modprobe button, fan, or any of these modules i get duplicate directories in /proc/acpi. without PNPACPI, the modules load fine, but the fans still don't ever seem to come on by themselves, and i'm afraid to let the processor go above 80C. /proc/acpi/thermal_zone/THM $ cat * cooling mode: critical state: ok temperature: 64 C critical (S5): 98 C so how can i get my automaic cooling back? if someone just wants to point me to the right docs, I don't mind reading up on this stuff. Thanks much, brian
