The reason why these never stop is because they are important parts of the Maemo system.

Don't mess with them, killing their processes may trigger a watchdog reboot.

thanks.. im understand now
but i had write a post again to reinob and now i waiting from reinob for the result and answer first.

@Hurrian : that right.. but does my device is normal, if..
250mhz ->2% then
250mhz ->10% then
250mhz ->4% then
250mhz ->20% then
250mhz ->6% then
250mhz ->22% then
250mhz ->2% then
250mhz ->15% then
250mhz ->6% then
250mhz ->17% then
250mhz ->11% then
250mhz ->26% then
and repeting again.. and again.
the percentage is jumping to high even after 5 minute from started it seem like doing something my ram is untable too.. increesing slow but can decreasing with fast too after closing unlike before staying stable increasing only a few. can you explain sir thanks..

Maemo automatically manages process groups and priorities.

It's normal for CPU use to spike.

hey.. what wrong with my device can someone explain to me... (im sorry.. im seprises and confuse too)
this morning after charging im turn on my device then i see my cpu at 250mhz they load only 1 into 10 percentage and always repeating prosessing under 10 percentage (standby-no open aplication) its seem normal again this 2 result of power top+terminal-X :
Total wakeups 1628, 54.3/s | IRQ 1202, 40.1/s | Timers 426, 14.2/s
HW wakeups 180, 6.0/s | Real gp_timers expired 93, 3.1/s

Total wakeups 1200, 40.0/s | IRQ 847, 28.2/s | Timers 353, 11.8/s
HW wakeups 95, 3.2/s | Real gp_timers expired 34, 1.1/s

its strange can someone explain to me.. yesterday i had reboot and turn on device for 3 times and nothing change. but right now..
i not sure my problem is done.. and what must i do if this problem came back again to my device.. thanks for help.

Are you half-**t ?
I asked you to post powertop full result (attach powertop.txt )for better guidance
with this information there is nothing wrong with your device
no one can help you with this information
and please stop spamming , post more details, then we will help you in finding out the issue
Thank you

yes sir..
but yesterday until my phone battery runned out, my cpu still repeating that prosessing.. i had reboot & swicth off for 3 times there no changes? but this morning my cpu device run always under 10% at 250mhz (in position standby-im not open an aplication). its weird

I dont understand.. what do you mean?
im wrote this problem base in true fact, im not spamming.. why i must spamming.. now simple question to you.. how to attach sample.. if today my device showing a different result from yesterday can you garantee you can explain what is the point problem at yesterday to me and all user (please dont jugde me like that)

Look. Your N900 is a computer. A computer, when turned on, usually DOES SOMETHING. Otherwise it would not be a computer.

If you have the screen turned on and are running a program (conky), plus a number of system programs that NEED to be running (otherwise you get no e-mails, no calls, no nothing), the computer will use some energy, meaning the battery will, fast or slow, drain.

Every N900 has a number of processes running. Xorg, to name an example, is the one handling the display. Pulseaudio does the sound. Hildon-desktop and hildon-home give you the user interface. Etc, etc.

If those programs were not running, your N900 would be a paperweight.

Now, if you lock/turn off the screen, most processes will stop doing things (because e.g. the desktop doesn't need to display anything), so your CPU will go to sleep and only wake up every now and then (e.g. 5 times per second) to check if, e.g. a phone call is coming in.

So from what you've posted there is no problem. You still haven't said WHAT THE PROBLEM is. We don't know how long your battery takes to run out from being full *and* what you're doing while this happens (obviously, staring at conky for hours will drain the battery faster than if you turn the screen off).

A way for us to know IF there is a problem and possibly diagnose it would be to provide the full output of powertop without running anything else (no opera, no conky, no nothing). With this it would be easy to spot if there's anything abnormal going on.

your device is fine. As reinob says N900 is a computer not a regular phone. Even my N900's processor jumps from 3% to 25%. its fine when you are running conky which uses cpu also.
