acpi thermal module is missing

[feta]

guys ...

i have an FS laptop with an athlon 3700+
i have installed the 32 bit version of fc3

i have compiled my kernel 2.6.9-1.667 to support acpi however
the only modules i find in /lib/modules/2.6.9-1.667/kernel/drivers/acpi are:
ac.ko asus_acpi.ko battery.ko button.ko toshiba_acpi.ko
(i dont know why i ve chosen toshiba and asus support but forget it...)

my problem is that i cant find the thermal.ko module...
at the moment i use cpufreq with an ondemand scaling governor or something like that
my cpu speed can be adjusted w.r.t. the load however because i am running some experiments on my laptop the cpu gets heated and what happens is that the bios is shutting down the machine to protect it.


I am forced to run my pc in a speed of around 1000MHz constant so it wont get very hot... how can i install this acpi thermal support (which correct me if i am wrong, adjusts cpu speed w.r.t. the temperature)

thanks very much
i would really appreciate any help

Hi,

Can you post the contents of the file /etc/cpuspeed.conf

It should look similar to:

VMAJOR=1
VMINOR=1
OPTS="-i 2"
#DRIVER="powernow-k7"
#OPTS="-a /proc/acpi/ac_adapter/*/state -t /proc/acpi/thermal_zone/*/temperature 75"

To read about cpuspeed see:

Lack of a thermal module is not your problem -- it is compiled into the kernel already.

If you don't have interesting things down

/proc/acpi/thermal_zone

then I should think about problems with your BIOS ACPI tables... do a

dmesg

and have a look for ACPI - related stuff.

thanks very much for your replies

so here we are:
with acpi=on apm=off in my grub.conf i have the following:

//---------------------------------
my cpuspeed.conf
//---------------------------------
VMAJOR=1
VMINOR=1
OPTS="-i 2"
DRIVER="powernow-k8"
OPTS="-a /proc/acpi/ac_adapter/*/state -t /proc/acpi/thermal_zone/*/temperat
ure 75"

do i need # infront of driver and opts?
actualy my system always shows a temperature of 75...

//---------------------------------
/etc/rc.local
//---------------------------------

do i need this scaling_governor with cpuspeed?

/sbin/modprobe cpufreq_ondemand
echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

//---------------------------------
and finally something very disturbing:
//---------------------------------

whenever i set acpi=on in grub.conf
i simply do not have internet...
my system connect normaly (bringing up eth0 interface during boot = ok )
however nothing works
by dmesg i get the following (this happens whenever i enable acpi)
NETDEV WATCHDOG: eth0: transmit timed out

have you seen something similar?

anyway thanks for your help

-> arthur_klein: the link for a previous post you ve send... the topic had started by me
however at that point i hadn't configured cpuspeed, i couldn't make my system go any faster than
800mhz when it can reach 2.4 ghz


-> andy_green: BIOS ACPI tables, i dont really know what are they... i ve pasted my dmesg.. do you see anything interesting? i saw that the chipset of my laptop supports also acpi 2.0...

thanks anyway, both of you, it would be very kind if you keep in touch

hi feta
I have seen these message

NETDEV WATCHDOG: eth0: transmit timed out
eth0: Transmit timeout, status 00000000 00000260
NETDEV WATCHDOG: eth0: transmit timed out

because my eth0 NIC's irq conflict with other device, you may check /proc/interrupts to find some clue.

[hcjiv]

I have the same problem with no reported IRQ conflicts. Hmm....
