I really have to stop the daemon now because else it fills up flash in no time.
Where is the log file located? I want to see those messages. I am using the same OC kernel.

Example playing a 160KB MP3 with built-in media player:

Clock fluctuates from 125mhz on up to 800mhz, but the cpu usage percent ranges from 50% to 53%. I would expect both values (clock and usage) to be relative and not such a wide margin of fluctuation with the clock and usage. If one is constant, the other should be. I could see if there is lag for one value to the next, but that should be an issue of displacement of values, rather than one staying always "constant" (the usage).

BTW, most of the time, cpu is at 125mhz, but does fluctuate for several seconds up from 500 to 800, but usage does not deviate from 50% to 53% range.
There is an Issue - Real Time. It is a reason why ondemand scaling governor pushes CPU to higher frequency and prefers to have some idling on that frequency.

Sorry, it is a long story - why it is needed.

@Matan and Lehto:
are you sure you're overclocking the DSP?
did also modify the tables in drivers/dsp/bridge/rmgr/drv_interface.c ?

It seems Nokia bought a little less reliable bunch of 3430 from TI - there was a couple of devices with hardware problems last Dec and I can account it to CPU unstability.

Just take into consideration that 3430 is sold by TI only in big quantities - that actually means the different approach for troubled chips and different reliability requirements for different bunches.

Hey guys - coming PR1.2 has a new kernel - http://talk.maemo.org/showpost.php?p=599660&postcount=2

"Updated packages
...
+kernel 2.6.28-20100903+0m5"

Be prepared to lose overclocking for short time.

it seems to idle at 250 now ?? no more 125....
id the dsp still 500 or has it changed back to normal??
DSP also has a couple of frequencies and 500 is a new MAX.

I think I will survive...

I have no idea why the telephone app does that.
I'll check whether replacing 600 with 601MHz will ignore such requests.
(a frequency that does not exist in scaling_available_frequencies should be ignored)
Hey titan,

Where'd you find that? I grepped for scaling_max_freq and didn't find anything in suspicious in /etc, /usr, /bin or /sbin except

/usr/share/policy/rules/rx51/policy.dresc

I don't think that's it though.

Everything else looks like just the bootup stuff.

I suspect titan's kernel will work fine; I believe it's based on the PR1.2 source tree.
