so it won't eat more battery in this case.


I only built smartassV2(tweaked) into kernel. because it balance between battery life and performance.
There are also include kernel module of ondemand and conservative, you could load them by insmod if you like.

Thanks... Pls try and include HighBigMem in the next version...

thanks for your kernel! i will try it now and report back

EDIT: unfortunately kernel doesn't work for me - i use it with paranoidandroid and rom was really sluggish at first (maybe cache-related...). then i startet setcpu for adjustments and the phone stopped responding with "colorful snow" on the screen. i pulled battery to reboot. - maybe my 9023 doesn't like 1,24 ghz (it is a bit picky, but 1,2 ghz at stock vol was never a problem).

@OP or @DaXmax: Is there anything I can do to help at finding the problem? logcat? or is it just my phone being picky?

yea, well, with stock kernel (and thalamus and matr1x and air kernel) everything runs fine, but i wanted to know, if there is a way to find out what exactly causes the problem with your kernel and my phone (which also might help somebody else). - raising the vol does not help that much, still some freezes from time to time (even though i'm above stock vols).

sorry, i mean stock rom

did you ever try to raise up your interval voltage?

FYI, here is the voltage sets from stock kernel of Infuse 4G (but it runs 1.2GHz):

clock / arm / int
1200 / 1300 / 1125
800 / 1200 / 1100
400 / 1050 / 1100
200 / 1000 / 1100
100 / 950 / 1100
