12/19: Need testers for kernel that can simultaneously battery save and overclock

Updated 12/19

bzo has created a new kernel here that needs testing:
http://forum.ppcgeeks.com/showthread...39#post2016367

Prior to this kernel, if startup.txt was overclocked, pm.sleep_mode had to be set to 2, disabling power saving features and halving battery life, or else sleep of death would occur. This new kernel allows overclocked phones to set power saving pm.sleep_modes and should improve battery life for overclocked phones significantly.

If you can help test, and provide feedback if it worked for you, it would be very helpful so that the update can be submitted to the kernel team.

whats the default pm.sleep_mode if you do not define it?

Confirmed, 0.

Is the speed decrease noticeable?

I have a tilt2 and I run Sleep Mode 0 with overclock at 671744. Thats 656Mhz. Short of the usual 768 I did but it gives me sleep mode 0 stable and better battery life... when its asleep. You know its fully asleep when the light turns green.

so is the decrease noticeable at all when you overclock under 700?

Things take a bit longer to load like gmail but over all still snappy, and seems more stable. also battery is a lot better.

The benchmarks showed there was a speed difference between overclock and no overclock, but I never noticed on in practice. Both are sluggish, I guess I'm not sensitive enough to detect the difference in sluggishness.

You managed to run both sleep mode 0 and overclock at the same time? Can you post your startup.txt? I'd like to try that.

just leave the pm options out and run oc options... but this way 12% in around 6-7 hrs
