Two bad points for 3.4-3...

Dim, just yesterday I did an initial install of 3.4-3 on my Dell Inspiron 2600 (it's about 200 years old in computer years). The install worked ok and initial exam shows everything ok, but I have not yet tested my wifi card. I will try to do that this evening. If it works, then I'll be able to test other software and certify that my installation is successful (and post accordingly).

Can you please provide some info on your laptop so that I can compare notes?

TIA

Jon

Jon, we have a small misunderstanding here: _generally_ installation is ok for my laptop, everything is ok, WiFi is up, USB works, etc. There are only 2 problems:

- I cannot anymore suspend it!
means: "klaptop_acpi_helper --suspend" starts suspend ... and back to wake-up (I don't know really what's going inside)

- Seems kernel was compiled without Centrino cpu_freq support
So, laptop is working all the time on the max performance and very quickly FAN noise become a problem...

Thanks a lot for your help!

i think you can solve the fan issue by loading the appropriate module.

I don't know which one that would be though, try adding the line 'p4-clockmod' to etc/modules. And install powernowd....

Newbie or not Newbie, there's always a question

Thanks, carlops, I've already tried, but it did not change anything
initially. Finally I went more in depth, and start to compare 3.3.1
vs 3.4-3:

- "cpufreq" module for Intel M is "speedstep_centrino"

- on 3.3.1 it started at boot, on 3.4 I've started it manually

- "/proc/acpi/processor/CPU0/performance" is absent on 3.4

- however, main "management" files for 2.6 kernel are located
in "/sys/devices/system/cpu/cpu0/cpufreq" (once speedstep_centrino
is started)

- difference:
3.3.1: cat scaling_available_governors => userspace performance
3.4 : cat scaling_available_governors => performance
file "scaling_setspeed" is absent in 3.4 (due userspace?)

- Normal "raw" way to change CPU frequency is:

# grep M /proc/cpuinfo
model name : Intel(R) Pentium(R) M processor 1.80GHz
cpu MHz : 1795.946

# cat scaling_available_frequencies
1800000 1600000 1400000 1200000 1000000 800000 600000

# echo 600000 > scaling_setspeed

# grep M /proc/cpuinfo
model name : Intel(R) Pentium(R) M processor 1.80GHz
cpu MHz : 598.648

- Workaround: as "scaling_setspeed" is absent here (3.4),
we may use "scaling_max_freq" instead:

# echo 600000 > scaling_max_freq

# grep M /proc/cpuinfo
model name : Intel(R) Pentium(R) M processor 1.80GHz
cpu MHz : 598.648

- CONS: "klaptop_acpi_helper" was not designed to work in this way (RFE?),
and you have to be root user (or change write permissions on
/sys/devices/system/cpu/cpu0/cpufreq/scaling_m*_freq according
to your security policy), ex:

# chmod 0666 /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

will give cpu_freq permission to any user:

$ echo 800000 > scaling_max_freq

$ grep M /proc/cpuinfo
model name : Intel(R) Pentium(R) M processor 1.80GHz
cpu MHz : 798.198
