acpi works fine with 2.4 but not with 2.6


My laptop(gericom blockbuster 1650) is working fine under debian with kernel 2.4.27, but i recently compiled the 2.6.9 and lost the performance profile management! And the ventilator is allways on!

can someone help ?

Do you have ACPI (and all its components) compiled into the kernel or as modules? I found that my power management didn't work unless I compiled them into the kernel instead of as modules. Try it and let us know what happened.

They are compiled as modules! I'm compiling the new kernel to see if your theory is good! I tail you later...

ok ... I recompiled incorporating acpi options in the kernel :
apparently, the CPU is well getting cooler and the ventilator stops correctly.
But here is some bugs :
my /proc/acpi/fan directory is empty
my/proc/acpi/thermal_zone/THRM/temperature file gives allways
temperature: 75 C
I don't have a /proc/acpi/processor/CPU1/performance file but have a /proc/acpi/processor/CPU1/throttling one.
The performance management I have on 2.4 is very useful : by setting lowest performance, the PC gets slower but the ventilator stays allways off. I'd like to do the same with 2.6 but no way

It's OK :
The CPU Frequency scaling options were compiled as modules. I made it hard and it works fine!!!
And the Default CPUFreq governor was on performance!!! I made it (userspace).
All works better than with 2.4!!

Thanks.

I did the same exact things with kernel 2.6.7, I have the power management control panel on KDE, the battery icon, on startup I can see the CPU frequency tables read corrrectly... but ...
I have tons of these this on dmesg:

Warning: CPU frequency out of sync: cpufreq and timing core thinks of 2123008, is 1791288 kHz.
