    Had Ideal kernel from yesterday and removed phone from charge at 7am. At 12pm battery graph looked strange and changed kernel to uvl. And here is the result. At 18 changed to 3G and used rDesktop for about 15 minutes and then back to 2G.



    I have always online exchange sync from 8am to 8pm and had a couple of phoncalls also after and before 12pm.

    Thanks a lot for this titan.

    However, I also need to mount luks volumes, can you add the following to the kernel config, to enable this:

    * Crypto:
    CRYPTO_SEQIV=y
    CRYPTO_SHA256=y
    CRYPTO_SHA512=y
    CRYPTO_TWOFISH=y
    * Device mapper:
    MD=y
    BLK_DEV_DM=y
    DM_CRYPT=y


    Thanks.

    If there are no major showstoppers I'm going to promote maemo22 to testing and hope for your votes.
    Do you have a patch (diff) for OC/LV changes only?
    Because package source of maemo22 has huge changes unrelated with it.

    (I work on some kernel changes but in testing I am limited by stock kernel module set and can't apply all changes).

    I had problem to update to maemo22 kernel. Installation suddenly stopped (permanently) and after reboot it entered never ending boot loop. Re-flashing of image + fresh backup saved me

    I was using ideal kernel at max 850MHz. Can't really tell anything more (no traces left). I'll try maemo22 once again with fresh installation. Lets see what happens.

    I wouldn't have mentioned it, but this happened to me also. (I wasn't using the ideal kernel, but the uxv or whatever it's called kernel.)

    Fresh installation did fix it for me -- I'm glad I had backed up everything.

    at first, a big thanks to titan and letho for their great work. I'm running titans latest maemo22 kernel at the "ideal" voltages with 500-900, and I have to say it really is a big difference to the stock clocks! Also all seems stable so it looks like I might have gotten a "good" chip.

    A few pages back there was the idea of a "reboot-loop prevention" by checking the time of last reboot and not applying the overclocking if the last reboot was shortly before the current one. I have adjusted the upstart script posted earlier to do just that. It will not apply the overclocking if the last reboot was less then 5 minutes before the current one. With this script there is no need to modify /etc/pmconfig (actually it would defeat the purpose of the check).

    The script will apply the setting as they were in the ideal xlv kernel as posted earlier by titan. Feel free to adjust them.
    Also YOU ARE RESPONSIBLE FOR CHECKING THE VALUES AND THEIR SAFETY. IF THIS BREAKS YOUR DEVICE I CAN NOT BE HELD RESPONSIBLE.

    So here is the script:
    Code:
    start on started dsme
    stop on starting shutdown
    service
    console none
    script
    	TDIFF=$(expr $(date +%s) - $(stat -t /etc/lastreboot |awk '{print $14}'))
    	if [ $TDIFF -gt 300 ]
    	then
    		touch /etc/lastreboot
    		echo 75 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/up_threshold
    		echo 150000 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate
    		echo "30 30 30 30 33 38 45 45 48 48 54 54 60 72 72" > /sys/power/vdd1_opps_vsel
            	echo 500000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
    		echo 850000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
    		modprobe bq27x00_battery
    		exit 0
    	else
    		exit 1
    	fi
    end script
    save this to /etc/event.d/overclock and reboot (or run "start overclock" as root to apply the values without rebooting)

    Now everything is OK again and N900 running on maemo22 kernel with following voltage settings
    Code:
    echo "30 20 25 30 33 38 45 45 48 48 54 54 60 67 72" > /sys/power/vdd1_opps_vsel
    Code:
    scaling_max_freq 850000
    scaling_min_freq 250000
    Let see how long battery will last. I have high hopes

    BTW: Is there still the same feature that after call 125MHz will be set to 250MHz? At least that happened to me

    everything except for twofish, sequiv is already enabled. maybe that's already sufficient for your purposes? I could enable the other two in the next upload, however,
