Have now used titans_250-900-lv-kernel-maemo20 for 27 hours before i needed to charge. During this time i used it as usual also got some time to sleep. It have been stable as a rock.
Next i will go for the 500-1000-ideal-kernel but have a question. I have seen some posts that the ideal kernel have the same problem as before with outgoing calls. Is that true? Is it possible to fix without doing the separate command in the terminal? It works good in the lv-kernal i just tested.

unlike the other low voltage the ideal kernel is NOT supposed to have the outgoing call problem.
sure. it's just the max. current that could damage the chip. so the damage would not be larger than with 600@stock.
Actually, technically there are two failure modes.
One is slow failure caused by thermal expansion (over-temperature). Current flow * time causes this.
The other is quick failure due to dielectric arcing. This happens when the voltage overwhelms the dielectric (ie. in the onboard capacitors) and arcs to other parts of the chip.
update! just flashed to titan's XLV kernel, the 250/500/600/800 version. I'm using this instead of the XLV 500/800 version for better battery life.
seems to be rock steady! tried enabling 125mhz under etc/pmconfig, got the same behaviour that titan got: that the cpu idles at 600mhz consistently instead of scaling down to 125mhz. in the end i switched off 125mhz mode.
great job, look forward to increased speed while retaining battery life!

Tried the 500-1000-ideal-kernel but it crashed and rebooted after 30 seconds. I then tried the 500-800-ideal-kernel.. it seamed to work. I then tried 500-900-ideal-kernel and it crashed. I will now try 500-850-ideal-kernel...
by the way.. Is there some type of log where i could see whats causing the crash? Everything seams to reset after reboot. It must be some setting with voltage that my phone don't like. I have been on 900mhz in the lv-kernel so it should be possible.
i appreciate that lehto and totally appreciate everything you have done for us but may i ask you as a last favour ? to share with us info on or your chosen kernal thats on your n900 so we can use too? cheers either way though . moepda
google and type in "how to overclock the n900" i think one of those search results will direct you to maemo central. thats where i got my kernels.

The 500-850-ideal-kernel did not work. So i decided to revert back to the 250-900-lv-kernel.. but hit the "cannot remove '/lib/modules/2.6.28.10maemo-omap1/modules.*" bug. I tried the fix proposed here without luck http://talk.maemo.org/showpost.php?p...&postcount=196
After this the phone just when black when trying to boot it. I flashed it with the flasher-3.5 from the computer. And have now reverted back to the lv-kernel.
I think as i can start up with the ulv/ideal-kernels i have problems with the lower mhz. Because as long as i keep a high mhz and do not let the phone idle it lives. So is it possible to have a kernel that is a bit higher than the ulv/xlv/ideal but lower than the lv-kernel?
The lv starts overvolting at 600 now but i think it would not be needed until 850-900mhz. As i could run at the speed of 900mhz (i think) while on the ulv and idle-kernels but then it died on the lower mhz. Also.. it seamed to last longer when i had the 500-800-ideal settings.
