    This is the same series of kernels present starting with SS 5.2 - the benefit of these kernels over my others is that (by default) logging is disabled. You can turn on logging by using the logging.ko that is present in the zip, which will go to /system/lib/modules with the others. However - unless you need to debug (ie. run a logcat) it is just taking up precious power.

    And YES - these will work for both Froyo AND Gingerbread. Included in the zips are most common filesystem drivers as well. If you do not know what they are, you do not need them ;)

    Standard rules apply - if you load up, and get stuck at the 'M' - first wipe CACHE. If still stuck - try a different kernel.

    Compcache is supported within these kernels - however, if you are using a non-SS ROM and have problems - you need to speak with that ROM's dev, as most of the work for compcache is in the ROM itself.

    Wow, the first improvement I am noticing right now are how cool my phone is staying, I dl'd the 1.25 first & installed it, then I clocked it @ 250-1.25, & with my phone plugged in charging I began dl'ing all the kernels to my sd card, & my phones did not seem to go up in temp at all, typically in that situation, while plugged in & dl'ing files back to back my ph temp would go up very noticably, but not with these, its still to early to give any long term feedback, but right now im impressed....awsome work as usual Chevy !!

    Hi Chevy,

    These are great. I went directly to the 1.25/7-slot/ULV and have been playing with it. *All the slots are right*, thank you very much :). And it's running cool and fast at least on my older Droid1, and I'm pretty confident it will run as well on the newer one.

    Btw, the camera works!

    Thank you HUGELY for all the great work!

    I installed a 1.2GHz kernel one of these new ones and phone rebooted twice already during a bench test. I think im going back to the logging type of kernel.

    The ONLY difference is logging - do not see how that could cause a reboot - however - whatever works!

    I went back to the 3-9-2011 kernels that are liquid compatible and it seems to be ok. I'm getting 1025 at 700MHz max and 1500 at 1200GHz. I have all the kernels on my SD card just in case I or other people need them :)
    Nice right!!!
    thanks Chevy!!!!!

    Chevy, do these kernels support init.d custom script loading? I know that you probably provided these along side your SS ROM built using CM source, so I am assuming that they do indeed support this method. If you could just confirm that for me, that would be great. I'm setting up this method alongside an AOSP source build, and I could throw in some extra performance enhancements using this method of script loading. Thanks!

    Not sure if this posted correctly under the buglist section. Apologize for dup post if so. But installed and flashed both ulv and lv of 1.25, 1.2 1.1 and 1.0. Seems to runn very hot when not doing much and ezpecially when using the browser gets very hot and then system freezes. Went back to 03/09/11 kernel of 1.0 and its back to normal now.
    Tried to find them but server down.... looks like been removed. Would like to put 1.25 on if I can.

    Hey Chevy, how do I go about loading logging?

    I `insmod /system/lib/modules/logger.ko` but I still don't have a /sys/kernel/debug, which I assume I need for aLogCat?

    Just trying to get a logcat with the newer kernel.

    Thanks for the work BTW, great kernel.

    Im running CM7 RC2 with chevy 1.1GHz ULV, when i try and verify compcache is running i.e. su /system/bin/compcache stats
    i get 'cd: cant cd to /sys/block/zram0'

    Is anyone else getting this error? maybe its a CM thing?

    You have to reboot afterwards - which of course is a problem since the insmod only works in that session. Turn logging on via my tools - in Options.

    And what you need for logcat is /dev/log/main

    From post #1:

    "Compcache is supported within these kernels - however, if you are using a non-SS ROM and have problems - you need to speak with that ROM's dev, as most of the work for compcache is in the ROM itself."

    You would definitely need to reach out to CM for help with this ...

    So in theory with logging disabled these kernels should have a little better battery life?

    On a side note observation, A few minutes ago I flashed the ulowV 1ghz, and after just a little web surfing, my ph is gettin crazy hot....dont think my droid likes the ulowV....time to flash a LowV.

    But by far I have always had the best luck with your kernels Chevy, I really like the fact that u are one of the few kernel devs who always "enables" all data collection, specifically "time in state" stats, I feel that is invaluable info in monitoring what ur ph is doing at any given time, its especially helpfull to see if ur phones & apps are behaving while its "sleeping".

    I have asked this question a few times to others but no one seems to have a definitive answer, that question being, does having the data collection, time in state etc enabled affect either positively or negatively batter life?

    And who do so many kernel devs not include the above in their kernels?

    I'm still able to run pretty nicely on the 1.25/7-slot/ULV kernel with both of my Droid1s.

    I did notice some unexpected lag especially on coming out of the Screen Off mode; disallowing the low 125MHz CPU throughout all my profiles has eliminated that. Speed is pleasantly crisp now and I'm continuing to be a happy camper...

    I had been experimenting with conservative mode, but in my tests it actually ran hotter and used more battery power than on-demand.

    I'm still trying to evaluate battery life now that I was able to eliminate the lag discussed above. I would say my Droid1s are definately running cooler though; that's a definate worth while thing and it probably points to better battery life too.
