Hi thanks for your reply on this.
How would i check /proc/bootreason i wouldnt know what to look for on /proc/bootreason or whats good or bad but i would be able to paste onto here whats on there maybe??

How do i do check /proc/bootreason?

Thank you.

at /proc/bootreason

the message does show even if you haven't overclocked, and overclocking is not the only reason for having powerkernel. Removing powerkernel will stop the message but not the random reboots (unless you have indeed overclocked), so you should find the reason for the reboots. If it is overclocking, you can disable it without removing powerkernel.

Oh, and try to lower your voltages. You don't want N900 running at stock voltages, it seriously drains the battery.
Try lv, then ulv, then xlv, and if your device can handle it, starving (my device can't handle starving.)

Thanks for your help.

How do i execute those commands are they all done in x term? If so would i need to input something before or after them?

My battery does drain ridiculously quickly if i use my phone constantly the battery lasts half an hour and dies.

Thank you,.

I just executed this in x term 'cat /proc/bootreason' it then said this: sw_rst

That normal?

Welcome to Maemo 5!

LV (low voltage) profile:
sudo kernel-config load lv

ULV (ultra low voltage) profile:
sudo kernel-config load ulv

XLV (XTREMELY LOW VOLTAGE) profile:
sudo kernel-config load xlv

Starving (XXXTREMELY LOW VOLTAGE) profile:
sudo kernel-config load starving

To save your profile in /home/user/.kernel (not needed, but recommended for testing lower voltages)
sudo kernel-config save myprofile1
(replace myprofile1 with a name for your profile)
You can edit the file in .kernel, then load it with
sudo kernel-config load myprofile1

Start with lv, and browse the internet, watch a few videos. If it's stable, go to XLV (most devices can handle XLV fine). If anything crashes while on XLV (for example, DSP voltage goes too low), add 1 to the voltage part of the kernel-config file. And try, and try again.

Hi there im sorry mate i just cannot seem to get that to work. No matter what i try whetehr it be sudo gain root, root or just nothing i am always getting an error saying: user is not in the sudoers file.
Dont know what else to do?

Thanks.

You need to install the root-sh script. You can find it here:
http://maemo.org/packages/view/rootsh/

This allows you to become root, and execute the commands above.
Do be warned, when you are root you are able to mess up your device, so use with caution...

Thanks v much for the link there.
Out of about the 50 on that website how do i know which one is best suited to my n900?

thanks.

You have a N900 running Maemo5, right?
Than you'll need the fremantle armel build. Fremantle is the codename for maemo 5, and armel is the architecture of the processor in the N900. Take the most recent stable build, so that would be 1.5. Here is the link
rootsh 1.5 for armel
Good luck
