Hello all.
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 *
<setting not supported>
cooling mode: critical
<polling disabled>
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
