Word to the wise. . Before upgrading to ext4 from ext3, make sure you backup your entire sd card to computer and have a recent nandroid. Iwas running classic, wiped cache and dalvik, upgraded to ext4, flashed my ext4 kernel of choice (it was uw8 havs- but im sure it will apply to this kernel as well), rebooted, and most of my apps were gone. Now, i expect that this occured bc i was not installing apps to sd card.
And, you can't revert to ext3 without reformatting the entire sd card. Hence, have sd backed up to computer along with recent nandroid.

Which recovery are you using?
I upgraded to ext4 via RA recovery, Smelkus mod (4.3), and my sd card had no problems. All storage and ext files remained the same.
But if downgrading I guess yeah backup your files.

Not need to backup entired sdcard, just ext gets wiped when upgrading extensions. And you can go back to ext3, but for that you do need to back up your entire sdcard as you will need to re-partion.......

I think most of my apps were on ext which is what was wiped when upgrading to ext4. Had everything titanium backed up so was no biggie.
Just saying if you gonna mess with Sd card, make sure to prepare for worst case scenario of things not coming out like you expect. I'm trying out some other roms now before I go back to tommys classic since the past few weeks has been crazy busy in og evo rom world.
Can't wait to properly try out calne's ext4 updates to his kernels. Thanks for doing this, calne. I hope you don't forget about us when you enter sgiii world. I have a feeling there are going to be many sticking with the og evo until something really phenomenal comes along. The current phones are really nice and have good guts, but our evos are really able to handle the newest rom innovations quite well

    Classic Sense Kernel

    This kernel started out of a request from tommytomatoe to have a stock kernel with sbc optional. So here I present a stock-"ish" kernel for gingerbread. Hopefully this will fill a niche where either the end user who likes the stock kernel, as well as the user who has issues getting custom kernels to run will both have something to flash that gives them that little bit extra without going overboard. There is no overclocking in this kernel, nor undervolting. This is for a stock experience with a few tweaks.

    What's in this Stock-"ish" kernel

    Stock Kernel 2.6.35.10
    Enabled Wireless N
    Powersave Governor enabled
    Perflock Disabled
    HDMI Fix
    GPS Fix
    3 Point Touch Check
    10 Point Touch
    Superior Battery Charging (SBC)
    Audio Boosted with On/Off Toggle (default setting is on)
    Fast USB Charge with On/Off Toggle (default setting is off)
    Reduced Wifi Voltage
    Front Facing Camera Fix (should work on all gingerbread sense)
    CIQ Disabled
    Fix for those having issue with hostpot
    Enabled EXT4 Support (applied performance patch)

    Instructions

    Apply with your preferred custom recovery and clear Dalvik Cache/Cache.

    For SBC
    It seems to help if you wipe Dalvik Cache/Cache.
    And make sure the phone is fully booted before plugging it in.

    For Audio Boost to turn on and off
    Code: 
    Audio Boost On
echo 1 > /sys/kernel/audio_boost/aboost
Audio Boost Off
echo 0 > /sys/kernel/audio_boost/aboost
Query Audio Boost Status
cat /sys/kernel/audio_boost/aboost
    For USB Fast Charge to turn on and off
    The below code will toggle it in the terminal, but a cool way to turn it on and off would be to support the original dev who put this mod together, chad0989 by purchasing his widget that controls this version of usb fast charge as well as the patch version. LINK TO WIDGET
    Code: 
    USB Fast Charge On
echo 1 > /sys/kernel/fast_charge/fast_charge_usb
USB Fast Charge Off
echo 0 > /sys/kernel/fast_charge/fast_charge_usb
Query USB Fast Charge Status
cat /sys/kernel/fast_charge/fast_charge_usb

    SBC info

    With most current development moving on to newer phones, I very much appreciate the folks that do still dev for our old Evo 4G's. I have one of the 003 hardware revisions that just get crappy battery life no matter what, but I've just learned to live with it (extended battery & chargers everywhere). I did notice long ago, back when Froyo was the shiznit, that SBC kernels helped more than would seem logical, and I'm very glad to see it available in a current, GB Sense kernel.

    Now to share some of the SBC wisdom that was shared with me by the kernel devs of that time period:

    1. When using an SBC kernel, any and all forms of battery calibration are now moot. The trickle charging of an SBC kernel does that better over one night than is possible using any normal calibration method.

    2. Everyone suggested installing Battery Monitor Widget, which I have been doing for over a year. I leave the bottom and top values at default (current battery charge % & current mA charge), but remove the battery image in the middle and have that displaying the current battery voltage (mV).

    Note: if you have an extended, higher capacity battery (1700 - 3500 mAh), be sure to go into the settings for the Battery Monitor Widget and change the battery capacity from the default 1500mAh to the value of your battery.

    3. Charge the battery until it has been showing a consistent charge rate ranging from 2mA - 6mA. Now, leaving the phone plugged in, reboot into recovery and wipe the battery stats. Boot the phone back up, let it charge until it's at the same rate as before, and you're done.

    None of this information is new, secret, or of my own creation. I just hoped to create a simple post that would provide usable info about using SBC kernels. There are a couple of possible or at least theoretical caveats to using an SBC kernel so I'll share those as well.

    1. There are L-Ion battery experts that say that doing this will shorten the life of the battery. This may be true, but based on the increase in daily, usable battery life I saw using these kernels, if it killed my battery every 6-months I'd still use them. However, the fact is that I'm still using the same extended battery that I purchased as soon as they were available, so I've not experience any dramatic shortening of battery life.

    2. Some of these same battery experts say that using SBC kernels can be a safety hazard, and that they can make the batteries catch fire or explode. I might have bought into this were it not for the fact that every L-Ion battery has a protective circuit built into it to prevent this from occurring. Also, in all of these claims I've as yet to ever see a name of someone that this occurred to, nor seen a single post by someone that had this occur.

    There were a few instances long ago of android phone batteries exploding; in one case the user was actually killed. However, in each of the cases that I read about, there were three things in common. First, all of these phones were from the same manufacturer. Second, the users were using the phone while plugged into the chargers. Third, and pay close attention here...none of these folks were using SBC kernels. SBC kernels didn't even exist yet.

    If anyone has any additional and/or corrective related information, I welcome it. The more accurate the information we all have is the better off we all are.

    Thank you for your time.

    updated OP. New version Classic V1.2

    Includes the front facing camera fix.
    also includes compiler optimizations.

    Ok I have a fix attempt for the Front facing camera... I had tried the code changes before, but I would get Media force closes and camera force closes.. But then I thought to myself, perhaps the fcs are from the data residing on from the apps and they would need to be cleared...

    So this is what I did, flashed a brand new install of a 4.67 rom (i used boot manager slot so I didn't have to clean out the phone rom), cleared system/data/cache and flahed the rom and flashed the kernel right after without booting first, loaded up the rom and no force closes...

    Now if someone is willing to test out this kernel (I used classic since its the least modified from source, so its a more stable testing base) to see if when using google hangout and 4.67 ota based rom if the receiver sees the you flipped/mirrored as well as your own display, please PM me... I'm only looking for a couple people to test it out...

    I also want to test how to get it to run without force closes on an already installed rom.. I'm thinking maybe clearing data on camera app and media app, rebooting to recovery immediately, clearing cache and dalvik cache, flash the modified kernel, clear cache and dalvik cache again to be sure, then reboot.

    Finally if both those work and get hashed out, then I want to see if someone with can do the two above procedures with a 4.54 ota based rom and see if it gets a flipped camera/video, or does it work for both 4.54 and 4.67 (i want to find out if I need to provide 2 seperate variations of each kernel for different otas or not)

    So in essence I'm looking for testers to do 3-4 things... one is to see if the kernel modification works to begin with on a clean install and if that works, then I want to see how we can get it to work so someone doesn't have to do a clean install... and to see if it borks on 4.54.

    Please only pm if you are willing to test it out... if it is successful, no worries I will release an update for Classic Sense and Underworld Sense.

    Thank you again to all who have shown interest in the kernels I have been compiling, and thank you to the testers and those who leave comments letting me know how its running (for both this kernel and underworld)
