With Lehto 125-950-500, a day without change of battery.
I can assume than user habits are delimiting battery life, anyway, nv kernel beating xlv... how is it possible? If 500 xlv=125 nv, and Lehto 950 ov> ideal 950 ov... ¿?¿?¿?¿
So again reinstaling 125-950-500... I'm getting crazy!!
i chose Lehto's because that was the first kernel i got from searching about OC.
let's say first to come is to be served....

BTW, there is cpufrequtils in extras-devel.
it contains cpufreq-info to summarize all info.

Be careful with that. I have erased the "current" link and rebooted without reminding to make it again. Now the device doesn't boot any more
only some poorly designed parts in Maemo5 use it instead of the more reliable `uname -r` approach.

its a known bug and actually nothing to do with the kernel
It happens when you get over a certain amount of items in you mydocs (appx 32 i think - or something like that)
Marked as fixed in PR1.2
Anyway to workarround this?
Seems strange but i dont like to see duplicated folders
help?

Here are my stats for the ideal kernel by the way
Current frequency: 500 MHz
Minimum frequency: 500 MHz
Maximum frequency: 810 MHz
FREQUENCY USED
1200 MHz 0
1100 MHz 0
1000 MHz 0
950 MHz 0
900 MHz 0
850 MHz 0
810 MHz 0.000 %
750 MHz 0.000 %
700 MHz 0.000 %
600 MHz 0.000 %
550 MHz 0.000 %
500 MHz 0.010 %
The rest of the time i.e. 99.99%, the CPU is idle (though I have clubbed all the idle states together)
EDIT: Have updated the numbers

My current plan is to replace the different kernels with a single kernel that can be configured while running. This would mean less maintenance for me, easier installation (from extras) and no need for reflashing.
In addition to min/max frequency settings it should have an option to select a voltage look up table
(normal, LV, ULV, XLV) and the possibility to disable some frequencies in the table
(e.g. 250 Mhz to get a permanent minimum of 500). I'm currently investigating whether this is possible.
http://my.arava.co.il/~matan/770/n900/vsel.diff
Disabling specific frequencies might not be as easy. I think that the easiest way is to add a scaling_allowed_frequencies to generic cpufreq code, rather than hacking ARM specific code.

managed to get the xlv on... no problems so far..
I got it to 1ghz temp.. I notice cpu goes either 500mhz or 1000mhz, it does not do 850 (default max) anymore...
also, does it only use 500 and 850 frequencies??
what I understand is, 1ghz uses same voltage that 600mhz stock uses.. ?? right??
titan any possibility to throw 500dsp in?? I dont see dsp mentionned in any of your kernels

The easiest workaround is to wait for the fix.
There is nothing to worry about.
Move items and the problem will go away.
