Possible problem with ACPI

Hello Bruno,

I saw your post to d-laptop in response to astryx last week, and I have a 
similar problem. I hope you don't mind me mailing you this way.

My system is a Toshiba Satellite A40 and I'm using packages powernowd and 
klaptop.

TIA for looking at this,

Frans Pop


My kernel is self-compiled from kernel-source-2.6.7 (version 2.6.7-4).

The output from acpidmp is available from:
http://home.tiscali.nl/isildur/toshiba/acpidmp.out.bz2

If I use the 'p4-clockmod' module to step my processor, I have:
fjp@strider:/sys/devices/system/cpu/cpu0/cpufreq$ cat scaling_driver
p4-clockmod
fjp@strider:/sys/devices/system/cpu/cpu0/cpufreq$ cat scaling_governor
userspace
fjp@strider:/sys/devices/system/cpu/cpu0/cpufreq$ cat 
scaling_available_frequencies
349991 699982 1049973 1399965 1749956 2099947 2449938 2799930

But during boot I also get (from /var/log/kern.log):
kernel: p4-clockmod: P4/Xeon(TM) CPU On-Demand Clock Modulation available
kernel: p4-clockmod: Warning: Pentium 4-M detected. The speedstep-ich or 
acpi cpufreq modules offer voltage scaling in addition of frequency 
scaling. You should use either one instead of p4-clockmod, if possible.

However, the 'speedstep-ich' module only gives me:
$ cat scaling_driver
speedstep-ich
$ cat scaling_governor
userspace
$ cat scaling_available_frequencies
2799930 1599960

And if I use the 'acpi' module I get:
$ cat scaling_driver
acpi-cpufreq
$ cat scaling_governor
userspace
$ cat scaling_available_frequencies
2800000 1600000 65535000 65535000 65535000 65535000 65535000 65535000 
65535000 65535000 65535000 65535000 65535000 65535000 65535000

So, the only driver that gives me a nice range of frequencies is 
p4-clockmod.

I'm having another problem, which is that linux ACPI doesn't seem to 
recognize my fan properly. The state is always off, even if I can clearly 
hear the fan running. (Not sure if this is related.)
/proc/acpi/fan/FAN$ cat state
status:                  off

My processor is:
