The kernel might have a conservative governor by default. Or you could install the kernel use setcpu just to set the governor and then uninstall setcpu.
[EVO 4G Android Development] VOODOOTRIP:
Looking for input, would really like to get this kernel to work. It runs really good until I start to put a lot of demand on the processor. Then it reboots the phone. Was oc'd to 1152 the dc'd to 998 but still did it. Tried freezing setcpu and still had the problem if I put a lot of demand on. Otherwise it worked like a champ. Would like to narrow down this gremilin. Any input?

Ok, call me blind, but I cant find the link to download: Kings BFS 9 and Kings new CFS 11, went to the site, and can't locate anything labeled as such.

Also, is this installed via ROM Manager, or?

[EVO 4G Android Development] trianglechad:
I'm having the same problems. Has anyone been able to overcome a similar situation? Does not appear to be the ROM, but rather kernel specific. Tried unistalling setcpu and juicedefender, problem persists. Using amon RA to flash after full wipe and fresh rom install. Hoping its something I can fix, but maybe its phone specific. Would a format of SD card help?
[EVO 4G Android Development] funcrusher:
If you look at the changelog for CFS #9, you'll see that he started using ondemand as default. I don't see it listed as changing in 10 or 11 and I'm not using this kernel, so I can't say for sure. FYI.

Well I'm about to charge my stock and give it another run guess ill notice the difference now that I've uninstalled setcpu

Soo... Im not seeing much improvement in battery life. in fact it is actually a little worse. I just spent two hours taking an exam so my phone was not being used at all and I'm down to 74 percent life. I unplugged on a full charge 2hrs and 8 minutes ago. Any suggestions?

ROM: Fresh Evo 3.3

Kernel: Kings #10

Android 2.2

PRI: 1.77

Hope thats all the info you guys need to help. if not let me know.

Thanks. Just flashed #11 so we'll see what happens. Will I have to full charge to see any differences. I'm down to 68 percent now from the previous kernel I had.
[EVO 4G Android Development] MJStephens:
You can try both cfs and BFS. And you can flash the zip through recovery. Just wipe cache and dalvik cache, flash the kernel and reboot.
[EVO 4G Android Development] sanjsrik:
NOT A COMPLAINT, MAKING AN OBSERVATION AND A SUGGESTION

Is it just me, or was this probably one of the most unintuitve ways to download a kernel? There's no direct link, going to the page is his ROM page and unless you know to go into the forums and Evo Development, you don't know where these kernels are.

I appreciate all the work, but how about a direct link to the kernels? It took me at least 10 minutes to figure out where it was as there's also no mention on the main page where the Kernels are, ROMs sure, just not these latest kernels.
[EVO 4G Android Development] david black:
Okay so first I tried cfs11 and now I'm using bfs10. I get better life than on the stock kernel with both but it's still just not good enough imo.

I'm finally just gonna give up on having the best battery life and go for performance only. I'll just carry my charger around constantly I guess.

Fresh Evo 3.3.0.1

[EVO 4G Android Development] overthinkingme:
Why do ppl recommend wiping the dalvik? is this new? noone recommended this even a month ago on any kernel thread...
[EVO 4G Android Development] jontorres:
Same here, took some posting to figure it out.
[EVO 4G Android Development] overthinkingme:
If you've used his kernels before you know they're in the forums..and everyone knows how to navigate a website.....

Meeting halfway might be to include a link to the new kernel on his homepage though..
[EVO 4G Android Development] xlGmanlx:
i always wipe both cache and davik-cache when flashing a new kernel, no exceptions. I assume everyone ALWAYS did this.

substandard, no other way to describe it you might as not even post a link and just say, navigate to my site. Which makes this odd since other Dev's have gotten spanked for only linking to their personal site

Anyone having problems with the SetCPU set to the conservative governor? I set my frequency and governor to conservative, and the frequency sticks at one speed. It does not move up and down as it normally does. I switch to On Demand, and things seem to work again. Switch back to conservative, and frequency gets stuck again.

[EVO 4G Android Development] xlGmanlx:
good question, not sure where i got that from, but its something that i have incorporated any time i flash a kernel. Only time i wipe is when flashing a new ROM, or flashing a new kernel, and its cache's only

I've been using King's kernels since I started flashing and I was curious to how come my audio will be saved where I stop in the music player (any) with the BFS kernels but not the CFS ones? King's BFS is the only kernel that does (I've tried netarchy's too) and wanted to know if anyone knew why that may be. Not saving my place for podcasts is a deal breaker for me when it comes to kernels, so I've stuck to King's BFS #9. I'm having the same problems with #10 as everyone else, so I'm anxiously waiting for BFS #11 to unveil itself. Thanks for any info and keep up the great work King!
[EVO 4G Android Development] fabdelkader:

Really how many posts are there going to be about setcpu or finding a link. Bookmark the kernel page, go to first page of this post, or kill yourself.... Not that hard, and alot of download links are usually at 1st page of a post even if theres 200 pages. Not trying to be a **** but wtf. Anyways on a stock rom o/c at 1190 can become unstable and cause fc sometimes so you might have to back down to 1113. Somebody posted yesterday about some fc on heavy internet load, I experienced this on games. Other than that this kernel is #1 in speed and battery life.

Second day on this kernel. Yesterday wasn't too great on battery. Installed SetCPU last night and set governor to conservative and charged it all night. As of right now I'm 14hr 26m since unplugged and I'm at 51% battery. I haven't used it QUITE as much as yesterday, but yesterday I was at 15% battery in less than 9 hours so I'd say today was a vast improvement. Tomorrow I'm going to test adding one profile on SetCPU when screen off.

Any chance getting the boot loop line uncommented so we can load ubuntu linux onto our EVOs?

From the links below:

change the CROSS_COMPILE= line to:

edit .config file

Uncomment the CONFIG_DEV_BLK_LOOP and write:

Did you turn off your phone when you charged or kept it on? Setting your governor, you mean by setting it conservative on boot?
[EVO 4G Android Development] phistyle:
on fresh 3.3 with kernel #11 and used my phone extensively today (playing wordfeud and messaging throughout the day, a few phone calls through bluetooth) took the phone off the charger at 9:00 am and by 7:00 pm it was completely empty. So about 10 hours...was expecting more but oh wells...I think I'm going to try another kernel and see if it helps..
[EVO 4G Android Development] ddublu:
What's weird is that I opened SetCPU set the governor to conservative and to run at boot but after rebooting, SetCPU isnt showing as a running service....why would that be?
[EVO 4G Android Development] ryanalan82:
There is no need to have setcpu running after boot anyways. First you shouldn't be using profiles, so no need to keep it running. Second, when you boot up it says setcpu had been granted superuser permissions, so after that just kill it cause it's now o/c'd with the scaling you set it to which should be conservative. No need to have it take up any memory in the background after that cause it's already done it's job.

[EVO 4G Android Development] dthomas03:
So i am guess you kill SetCPU with advanced task killer?
[EVO 4G Android Development] ryanalan82:
Uninstall/reinstall setcpu. If that doesn't work, uninstall setcpu, wipe cache, dalvik, reinstall kernel, reboot, reinstall setcpu. Oh and king said to do the cache and dalvik on his site under the kernel downloads, before installing a kernel.

And no I don't use advanced task killer, that would be stupid with froyo. Just system panel, to kill after startup and every once in a while, and keep an eye on things.

[EVO 4G Android Development] Niviac:
Actually, looking at your post it shows your phone is staying awake 100% of the time, my phone is doing the same, Battery life isn't great, anyone know why?

When I run powertop I'm getting about 70-90 wakeups per second, which I don't believe is out of the ordinary.

I just wish I knew what was causing this, if my phone could go to sleep my battery would be great

not sure if you have apps2SD installed? That might be the only way that i can think of.
[EVO 4G Android Development] sgt. slaughter:
you are correct. it wont show up as a running service unless you have the widget out.
[EVO 4G Android Development] MJStephens:
I keep my phone on at night when I charge it. And I usually "top it off" on my 15min drive to work. As far as the governor, I just use the main page of Setcpu to set the governor and then kill setcpu with system panel. The way I've come to understand is you can change the way the governor acts and then u don't need setcpu running anymore unless you're using profiles.
[EVO 4G Android Development] Biofall:
A lot of the newer kernels are doing this. I suggest rebooting, then killing all tasks right on startup. So far it works almost every time. At most you might have to repeat two or three times. If it doesn't work after 2 or 3, it's a rouge app, and you can just use system panel to identify it.

#11 is pretty amazing. It drained pretty normally(fast) from 100-60% and then flatlined at 60%. It sat there for 4 hours with no change. I'd consider myself a heavy user.

Check your up time vs. awake time. Also, if you have something like SystemPanel installed you can get a live look at your CPU usage. Once in a while my CPU usage gets stuck at 100% for whatever reason. Once I reboot my phone everything goes back to normal.
[EVO 4G Android Development] Biofall:
As the guy above me said, your phone isn't sleeping. That's almost always the issue, and these newer kernels seem to do it ALOT. Install system panel, reboot, and kill all tasks on startup. Repeat once or MAYBE twice, but you should be good.

Although I laughed super hard because I say this all the time, that sure isn't very helpful :P

just a little confused, I would appreciate the clarification
[EVO 4G Android Development] Noxious Ninja:
No, you pick one - either CFS or BFS. Some people find one works better, some find the other does. CFS is a bit more updated at this point.

You should also wipe the cache before flashing the new kernel.

The main difference is the process scheduler, the part of the kernel that decides how multiple apps share your single processor. CFS and BFS are two different strategies for dividing up the processor time.

Battery Drain Revelation

I also have been having issues with battery drain and have been doing all kinds to troubleshooting; wipes, restores, new ROM's, kernels, etc.; then it dawned on me that I kept plugging in my favorite theme, Riptide9's ColorNClear.

Long story short reinstalled Fresh 3.3.0.1 no theme; installed all my other apps. and problem solved, my EVO now shows UPTIME higher than Awake time and great battery life again.

So apparently my favorite theme somehow corrupted the ability for my phone to go to sleep.:confused:
[EVO 4G Android Development] bigdaddie:
I can confirm that CFS 11 is a bit of a battery hog. I installed CFS 10 today and I believe that it is better than CFS 9 in battery and performance. I use my EVo as a golf range finder. With 9 I would have about 30-40% battery after a round, with 10 I had 60%. YES I started all with a fresh charge. So I am sticking with 10 for now. It may have some FC issues, and if I confirm, I will go back to 9; otherwise, I would recommend either CFS 9 or 10. The BFS builds did not work well with my device.

[EVO 4G Android Development] Biofall:
You have to check twice and compare the differences.

1. Check times, note difference.

2. Turn screen off for a minute or so.

3. Check again, and see if the difference is larger.

If it is, then you're ok, if not, you need to try what I suggested.

Now for my report on 11. It almost always prevents me from sleeping, and when I am sleeping, I get a very high "system" usage. Sadly, a lot of the newer kernels are doing this. I give up lol
