That didn't really work for me. I had screen off enabled already, and I turned on screen on as well. At first it didn't help at all. Then for a few tries it did actually seem to be better. Then it went right back to making no difference.

I'm having issues with WiMax on this kernel that I haven't been seeing on the stock CM7 kernel. After the device sleeps for awhile, WiMax gets stuck in either "turning off" or "turning on", but it also doesn't fall back to 3g. I have to reboot to get any data connection back. I'm seeing this on 37 nightly and on final.

I only jumped on the CM7 train with RC4, but from what I read, some people were having similar problems on stock until recently. Are there some recent fixes in the stock kernel that still need to be ported to SZ?
[EVO 4G Android Development] drdrewdown:
there were some wimax commits in the recent nightlies that MIGHT need to be merged..
[EVO 4G Android Development] luisrcastillo:
This has happened to me on the stock kernel too. I haven't seen any updates to the cm kernel about WiMax lately. The only commit regarding WiMax was to the ROM itself and that was the reconnect bug. I think this commit came after RC4, though I don't remember.

I use our ROM and this fix has been implemented so If I leave WiMax my device could sleep for hours and when I started using it again WiMax would continue to work without requiring a reboot
[EVO 4G Android Development] luisrcastillo:
The kernel should not have any impact on wakelocks. There might be something running in the background (bad sync or something) that is keeping a wakelock. I am using the Savaged-Zen ROM and I have not had any wakelocks at all.

For those still unable to get GPS to work!

While reverting back to a sense ROM yesterday to do some benchmarking I inadvertently lost my GPS after flashing back to CM7. To correct this I attempted to apply the "FIX" and was unsuccessful.

So, I started trying all kinds of things and finally discovered a step that was missing in the "FIX". After entering your MSL and allowing the phone to fully reboot the Sense ROM. It is important to leave GPS ENABLED when returning to recovery for the restore. I have been able to reproduce this and it seems dependable (at least for hardware 004).

Modified Steps:

Download MSL Reader from the Market and get your 6 digit MSL number

Make a nand backup of current ROM - or you can start from fresh again

Flash Sense Rom

Enable GPS and verify it works

From the dialer input ##GPSCLRX#

Enter MSL

Allow to fully reboot the Sense ROM

Verify GPS still works

Very Important: Leave GPS enabled and boot to recovery

Restore your backup to return to CM7

Hope this helps someone!

@ the Dev's

I'm using CFS v.1.1 and if you didn't know, Viperboy worked out a script to lower the voltage of ASOP custom kernels. I was just curious as to your thoughts on this script and if it should even be used/needed with your kernel. I've tried running 100mV, 75mV, 50mV, and 25mV...100mV is no dice, nor is 75mV. 50mv works for a little while and then my phone freezes and the same with 25mV. I know the tolerence levels varies from device to device, but again should users of your kernel even need to run scripts like these?

Thanks, just want to here it straight for you all.
[EVO 4G Android Development] mrufino1:
I had the same issue and was wondering the same thing. However, I am getting ready to flash the sz rom as well (probably tonight- I use my phone for work so I have to make sure there are no issues during the day), so I guess in that case it won't be necessary. The kernel has been working really well without the voltage script though, I guess all of us who are into aosp are always just looking for anything that makes stuff a little better.
[EVO 4G Android Development] sag7392:
I agree, I am getting great battery life without the script as well. But like you said, we are always looking.
[EVO 4G Android Development] renizo:
Your kernal is crazy with the battery and everything else. I am running CM7 and the only problem i notice is that the 4g at time will be stuck trying to turn off. My only option i notice to fix it is to restart my phone. Is there a fix to this. It only happens when im using this kernal. CM7 stock kernal works great but has no sbc. Does this happen on your rom if not ill give it a shot, can anybody help me out.

CM7 Kernel Problems?

Is anyone seeing any problems where when you flash the kernel onto a phone with CM7, the kernel flash causes a reboot loop? I have tried the CFS and BFS version and neither seem to work for me.

Thanks!
[EVO 4G Android Development] Lento10:
I have the same problem, the double boot on the splash screen.
[EVO 4G Android Development] Arrogant49:
Yup same here
[EVO 4G Android Development] bender1077:
Just flashed the CFS with CM7 no issue. First boot after a new kernel flash usually does take a little time. Mine took about 5 minutes.

HW003
[EVO 4G Android Development] y2kdread:
Are you running the release version of CM7 or one of the nightlies/RC's?

And the problem is that it just doesn't boot. I get the white boot screen, then it reboots. It does this over and over again and does't ever boot into the ROM.
[EVO 4G Android Development] mdean1981:
Ok this is probably already been answered but this thread is a bazillion pages long. In the newest kernel with cfs-sbc what governor is best to use for battery life without sacrificing major performance. I use CM7 and use the performance settings. I currently have mine set to smartass with 128 and 1190. Hows that?
[EVO 4G Android Development] LifeInTheGrey:
With such a low minimum, you can experience screen wake issues, and regarding the performance increase, clocking as high as 1190 has a negligible performance increase with a greater amount of drain (costs outweigh the benefits, IMO). If you want optimal performance, I recommend 245 min / 1113 max with the SavagedZen governor. That should be very snappy, and still battery-conscious.

Just as a side note, I keep mine at 245 min / 906 max with SZ governor, and do not notice any performance problems. I do notice the significant battery increase, though. ;)
[EVO 4G Android Development] mdean1981:
Next question. For some reason I can't download anything after switching to this kernel. I can't update my apps but I can browse just fine. My phone has also been up at a full charge and unplugged for 45 minutes and down 7%. Suggestions?
[EVO 4G Android Development] backspacepc:
Boot into recovery, and clear the cache and dalvic-cache. That should clear the app issue up. As far as the battery, it might take a charge or 2 for everything to settle.
[EVO 4G Android Development] rsatmans:
Does anyone have the voltage numbers under the savagedzen governor?
[EVO 4G Android Development] bbedward:
The voltages do not depend on the governor, the voltages are determined by the frequency it's running at.
[EVO 4G Android Development] rsatmans:
So are the voltages different using this kernel vs stock?
[EVO 4G Android Development] mwielgosz:
Well yes. This kernel implements undervolting which saves you battery. You also have the ability to change voltages on the fly.
[EVO 4G Android Development] lopezpm:
I had the same issue with the battery, so I went back to 1.0.1 which is amazing with battery life.
[EVO 4G Android Development] sd2649:
Yes, this... I need SBC and 4g! The stock kernal is the only one that has FULLY functional 4g...
[EVO 4G Android Development] MizzouBrent:
Running 1.1.0 bfs and have been unplugged for 7 hrs. With moderate use I am down to 63%. Back to cfs I guess?

It's the first time I've tried a bfs kernel and the battery life seems subpar. Using the SZ governor.

Every 4g commit in cm kernel is in this kernel so it's not the kernel causing issues
[EVO 4G Android Development] rockenrooster:
Just a thought. Would it be possible to change the shutdown voltage in the kernel like we can with the CPU voltage? I would be nice to see if we can gain anything in terms of battery life by lowering the shutdown voltage to something like 3.2v. Currently my phone goes dead around 3.6v. I know batteries can be damaged if discharged below 2.75v - 3v.
[EVO 4G Android Development] atoy74:
Is anyone else experiencing poor battery life with the new 1.0+ CFS kernels. I'm getting about 10% drop in battery life per hour. 0.2.1 was much better.

Rough tests -

Ver 1.1 - 3.5 hrs light use - 74%

Ver 0.2.1 - 4 hrs light to moderate use - 85%

I'm currently on CM7 Final but also experienced this on CM7 RC4/3
[EVO 4G Android Development] LifeInTheGrey:
Have you tried a full wipe? Or at least fixed permissions? Jumping from .37 to .38 was substantial, I highly recommend you try those methods rather than merely wiping dalvik and cache.

I have spoken.
[EVO 4G Android Development] bkrodgers:
On my phone, I can definitely say there's something up with SZ and 4G. Tiamat and the stock CM7 kernel have 4G working pretty close to flawlessly for me, but SZ clearly causes issues. I can flash back and forth between Tiamat and SZ and see my 4G issues go away on Tiamat and come back on SZ. I've also seen the issues right after a clean flash of CM7 and SZ.

I'm not bashing your work, and I'm fine just sticking with one of the other kernels. But there's definitely something up, at least with my phone. Maybe 2.6.38.2 has something to do with it?
[EVO 4G Android Development] bbedward:
I'm in the process of rebasing the kernel, because the tree has become very messy :eek:

Anyway, once that's done we can release 1.2.0 which should resolve all of the weird issues *some* people have, and we can release a working incredible, nexxus one, and bravo kernel too :D
[EVO 4G Android Development] housry23:
Good to see that kernel development has not stopped. I was starting to think that with the SavagedZen Rom development going on the kernel development had slowed to a crawl. Looking forward to the improvements. Keep up the good work guys.
[EVO 4G Android Development] atoy74:
Yes, I always do a full wipe. What do you mean by substantial? You're seeing better battery life?
[EVO 4G Android Development] drdrewdown:

Im using CM7 Final and stuck with it and using SZ 1.1.. I can say the Battery Benefit Im getting of an AOSP is totally better then off of a sense rom.

Lately Ive been Leaving my phone in my clip more often. Have gotten a total of 5 texts per day and 2 or 3 phone calls. So ive gottena good measure at what my battery performs like on minimal use and I dont know if the following numbers and scenarios are bad or good in anyone elses mind:

CM7 with SBC SZ 1.1

At Job(9-5:30pm) on Roaming at "1x": 59-65% left over

After work 5:30-7:45 im at 3G: 40-49%

When i get home in the boondocks of PA with no service: 14% on some days and above 20% on others when i finally plug into charge at 9pm

[EVO 4G Android Development] gpz1100:
How does one go about adjusting the various governor settings (up/down thresholds, frequency steps, etc..) With this kernel?
[EVO 4G Android Development] Circaflex:
Do you mean editing the kernel itself or via the phone?

For governor settings go to settings then cyanogen settings then performance and you can change them there.

To change the HAVs steps i believe you need to use the sysprefs commands found somewhere in this thread
[EVO 4G Android Development] gpz1100:
Mainly just referring to the governor settings.. Only thing under cyan/performance/cpu is setting which governor, and min/max freqs.

I'm looking for the actual governor parameter settings. I know they're adjustable, just need to know where.

CONSERVATIVE_SAMPLING_RATE

CONSERVATIVE_UP_THRESHOLD

CONSERVATIVE_DOWN_THRESHOLD

CONSERVATIVE_FREQ_STEP

[EVO 4G Android Development] ChickenArise:
Additionally check Spare Parts to make sure that you haven't adjusted any animation speeds. The names don't line up, but you have to disable it to see the animations. Also check that you have "Show animatinos" set to "always"

yeaaaaaaaah BFS for life!!! winning!

Hey guys ... great work on this kernel

Rnning 1.1 and I get lower stdev numbers with BFS than CFS

CFS: avg=52 stdev=12.4

Hope that helps anyone looking to choose BFS or CFS!!

are you on SZ rom? this is the kernel thread. so if you are running some other rom it won't be there.
[EVO 4G Android Development] wingzfan:
I was kinda wondering about that. I was on the cm7 final running the sz kernel but I guess I should switch over.
[EVO 4G Android Development] thedudejdog:
they are talking about making a "sz kernel app" that gets installed when you flash the kernel, for other roms. but right now sz rom has a lot of kernel control settings built in. i recommend flashing it. just nandroid before so if you don't like it you can go back

Did you guys fix the dump_image problem that happens on your kernel?
[EVO 4G Android Development] luisrcastillo:

[EVO 4G Android Development] thedudejdog:
what is a dump_image problem?
[EVO 4G Android Development] Techronico:
When this kernel gets rebased, and updated with the latest HDMwIn ESID fix, and fixes the image dump thing... It will be rock on time because you guys have the only .38 kernel for the EVO which fixes the usb issue with all .37 kernels. I know this post doesn't contribute anything but it helps me in case I'm wrong on any of this for someone to correct me.

Thanks for all the hard work guys.
[EVO 4G Android Development] bbedward:
I'm having an issue with the rebase that i'm trying to find (but havent found it yet). Hopefully it'll be done later today.
[EVO 4G Android Development] Shinzul:

[EVO 4G Android Development] BlueHarford:

[EVO 4G Android Development] Techronico:
The dump image problem was a minor issue that prevented kernel manager from installing kernels for SZ users. They are rebasing now so it should be smooth sailing from here on... Until @Shinzul releases the money printing app and everyone has to @Shift again.
[EVO 4G Android Development] Funkmon:

Still 100% CPU at full charge sitting on the USB cable. Everything else seems to work fine, but since I use the phone plugged in quite a bit there's just no way I can use this kernel. Everything comes to a complete stop once the phone hits 100% (whether it's finished charging or not). Up to 99% is perfect. Buttery smooth, fast, etc. 100%...boom. CPU immediately spikes to 100% (no matter what governor I use) and the phone is completely unusable.

NO that is not the final build

Everything on that mirror that is not zendroid is only for testing purposes, none of those are the latest git that 2.0 will be

the final builds are on the mirror now, as the standard names. I built them manually so they can be released, they should be on the official mirror soon
