Switch to voltage control for overclocking and undervolting because its very up to date where as setcpu hasn't been update as recently... its very straight forward and not as conplex as setcpu ;)

Kernel Issue or CM9?

I flashed the updated Shadow Kernel for CM9 yesterday - noticed a differnece in speed right away - but I had a problem during a call today - I can't say for sure that it is related to the Kernel (I know just enough to be dangerous) so I thought I would ask -

During a call - I tried to enter my passcode on the keypad (to access voice mail messages from my work/landline voice mail system ) and there was no recognition that I had punched any numbers -

I thought I had been able to do this before flashing this kernel when i was stock - so I reflashed the rom to go back to the stock kernel - and tested it - and it works fine. Now the funny thing is - while I am punching the numbers on my phone I cannot hear the beep beep beep beep that you normally hear over the phone when you press your keypad, but my passcode worked so it must have transmitted just the same.

Prior to going back to stock kernel - was the problem I had related to the kernel or is it a random issue that is more related to CM9?
[Epic 4G Android Development] bigdbag:
I, too am getting random reboots. They're fairly few and far in between, but still. I have all frequencies enabled up to 1300, with no UVing from stock kernel settings.

Sett at CFQ, OnDemand.

I had no such reboots running stock CM9 kernel.
[Epic 4G Android Development] socos25:
You also were not over clocked on the stock kernel. Try dropping down the OC, and backing off any undervolts.

Do I need to do anything special to get the phone to communicate over USB to a PC after flashing?

When I plug my USB cable in, I get the charging light, but the phone doesnt not prompt me to turn on USB connection to the PC.
[Epic 4G Android Development] sonarchist:
Are you asking because you intend to transfer bbelos' kernel over to your device after dl'ing to pc?...........Have you tried a direct dl to your device?................(as for your Q, A: for starters try a different microUSB cable, such as a blackberry as a lot of us have had steady + immediate USB connection w/ this.)
[Epic 4G Android Development] judogti:
I rebooted both devices and it fixed itself. It probably wasn't related to the shadow kernel flash, just coincidence.

Appreciate the reply.
[Epic 4G Android Development] czechpunk:
Anyone else having problems using audio through USB? v.02 worked fine, but v.03 won't. I've downloaded twice and checked md5, neither flash has worked...
[Epic 4G Android Development] honnt:
Yeah, I'm seeing that too.
[Epic 4G Android Development] bbelos:
Ah yes, I should have caught that. The latest CM kernel uses different audio drivers so I need to modify my dock audio patch. I will get that fixed tonight. Thank you for pointing it out.

I'm having issues with battery drain on alpha3. I have better batter stats and set cpu readings that are telling me its not sleeping possibly due to kernal wakelocks. Partial wakelocks are fine.

Any ideas? I already attempted a reflash fresh of everything.
[Epic 4G Android Development] socos25:
That's not the Kernel, it is CM9, I can get 30 plus hours of decent usage out of CM7, but I get around 22 with CM9. Its not terrible but I don't know if it will ever be as good as CM7 on battery, but I guess more features plus hardware acceleration equals less battery.
[Epic 4G Android Development] bbelos:
Here's a post from wispofates in the CM9 thread. I ran the command and saw a bunch of google map entries. I cleared my Maps app data and they went away for now. I will see if they come back later, and if my delayed work has reduced. Everyone with delayed work issues should try this and see what it comes up with.

Green Flash with low brightness setting?

Ive read some posts about a green tint with the voodoo controls and the shadow kernel. Im very new to shadow kernel (3 days now) and I do not have the voodoo color app installed. But I do get a green flash when I turn on my screen with the brightness set low (either by automatic or manual setting). Is the only way to get rid of this is to use a brighter settings? I hope this makes sense.
[Epic 4G Android Development] czechpunk:
Does the green screen thing last that long? Is it really that inconvenient? I've seen it but it doesn't bother me and it goes away in less than half a second on my phone, but I guess YMMV.
[Epic 4G Android Development] judogti:
No it doesnt last long, more of an annoyance than anything (and I wasnt sure if it was damaging the screen for any reason?). Just looking for any more information on it. Why it happens, can it be fixed, is it ICS or kernel related, etc....
[Epic 4G Android Development] czechpunk:
I got ya, just making sure it wasn't anything serious. From what I've read, it's caused by gamma settings in voodoo color being too low. Nor sure how to fix except changing settings and seeing which one stops it.
[Epic 4G Android Development] bbelos:
It actually seems to be a factor of both the gamma settings and the screen brightness. The lower the screen brightness, the higher the gamma needs to be to eliminate the green tint. A higher brightness allows for lower gammas. If you leave your settings on Auto Brightness, sometimes you will see the green tint, other times you will not (depending on the gamma settings and your surrounding lighting conditions).

If you are a person that likes to set your own brightness, you should be able to find the right gamma settings to never see the green tint. If you're like me and just leave it on Auto, sometimes I see the tint and sometimes i don't. I believe I can control the minimum brightness on the kernel side, but i don't want to force people to use a higher brightness than they would like. For now it's a minor tradeoff for voodoo color functionality, at least until I have time to study it more.
[Epic 4G Android Development] A_Flying_Fox:
Can I flash v3 if I'm on alpha one stock kernel?
[Epic 4G Android Development] czechpunk:
I wouldn't. It uses different audio drivers for one. I know bbelos has posted before that flashing v.02 over alpha 3 would break something; I imagine the same would be true flashing v.03 over alpha 1. Then again, I could be way off base...
[Epic 4G Android Development] hayzooos:
I was hoping flashing this kernel would reduce the locks keeping the phone awake, but that's not the case. As of right now, I have an awake time of 2h44m with an screen on time of almost 54min. That's almost 2 whole hours the screen is off and the phone is still running. No streaming music, nothing like that.

Kernel wakelocks state mmc_delayed_work is at 53min and deleted_wake_locks is at 17min.

Is anyone using Voltage Control, or are you just using what's built into CM9? I also noticed 100mhz isn't sticking either, when it's plugged in, phone is running at 200mhz it seems according to CPUSpy.
[Epic 4G Android Development] bbelos:
v0.1 works fine on alpha one, from what I remember. Any reason you're not using a newer alpha?

If you're coming from stock, I would expect little improvement in the wake lock issue. My kernel is based off of the stock kernel, and I have not yet made any modifications that would have influenced the lock behaviour one way or the other.
[Epic 4G Android Development] hayzooos:
I am, and thanks for the input. I didn't know what kind of improvements were made to the kernel, but it doesn't sound like many. Are you planning on making any, or since we're basically on a weekly release, does it not make sense for you to spend the time when people may only get a few days out of each kernel?

EDIT: Any input on what may be causing the wake lock issues to begin with?
[Epic 4G Android Development] bbelos:
See this post. I'd be curious to see your results. It might help tell you which app(s) are tying up the sdcard.
[Epic 4G Android Development] hayzooos:
I haven't tried what you posted, but I'll look into it. However, I did run a test which brought good info. I reset my cpuspy on the way home to see what was going on. I was driving for 7 minutes, checked it and it had spent almost the whole time in deep sleep. However, shortly after I clicked it off, I got a gmail email so the notification LED came on. I decided to leave it until I got home and didn't check it, touch it, nothing. When I got home, sure enough, 16 minutes at 200mhz and still 7 minutes in deep sleep.

Checked the email, reset stats, checked it again a few minutes later and all deep sleep.

TL;DR - Seems as though notifications are keeping the phone awake.
[Epic 4G Android Development] bbelos:
ShadowKernel-CM9-v0.4.0

This incorporates the latest multi-touch fix. Alpha 4 also has improved notifications which should result in better deep sleep. You can read the other improvements on the CM blog.

Green screen... voodoo color... gamma and brightness too low... answered in this thread... answered in every other kernel thread that uses voodoo color... answered in even more threads in q&a...

If you get a green screen turn either your brightness up or your gamma in voodoo control, or both.

Search does amazing things.

Do you need help with voodoo control? I know its a hard app to understand but I'm willing to hold your hand and help you out. First step is to go back one page and see the post about gamma from bbelos himself ;D

Is this kernel kexec compatible so I can update my modem using the bml flash?

Thanks
[Epic 4G Android Development] A_Flying_Fox:
Kim updating to alpha 4 finally. I stood on a1 because its bugs were easy to squash when they showed up and a2&3 seemed way different with their own bugs and didn't feel like relearning my phone again for experimental fixes, but a4 seems easy enough to work with.

I'm also going to flash this kernel from the get go because I fluffing miss my blacks looking black lol and if any bugs happen that I can't figure out how to troubleshoot, well you're one of the few who actually tries to replicate and fix it when someone reports lol

does it flash voodoo control app like your gb kernels or will I have to DL from market?
[Epic 4G Android Development] A_Flying_Fox:
It can't USB tether without kexec support right? If that's true I'd say you can

[Epic 4G Android Development] bbelos:
It does support kexec. Although USB tether has nothing to do with kexec.

Correct, it currently does not include voodoo sound but it's on my list to add back in when I have time to test it. I took it out dating back to when CM7 had the whistling feedback when voodoo sound was included.

I would like to report back and say that battery life has gotten better and it is almost on par now with what I got on CM7 sans juice defender (really annoyed me waiting on 3g).

What I did:

Clean new flash of alpha 4 and gapps

Flashed kernal

Flashed supercharger

Let market reinstall most all my apps (exception of a couple games, amazon apps, and randoms retrieved through titanium)

1200 overclock with -75 across the board and SIO

Supercharger setting 7

Kickass kernalizer without IO tweaks

3G supercharger option 4

Got this as battery life today (the random drop is my phone rebooting after trying to get up to 100 tabs in chrome...if you make it there to see that damn smiley let me know)

[Epic 4G Android Development] Ceelos09:
Wasn't the feedback caused by our Victory Audio Drivers that were acting up? They *should* be fixed now that our Devs have ported over the Crespo Audio Driver and the matching libs (I think) from the NS4G, right? Or am I just being hopeful :p
[Epic 4G Android Development] luna_c666:
Agreed, I really want to use this kernel but the lack of voodoo sound is the only thing stopping me, I absolutely have to have it in my car or my system sounds like crap, and I use my phone exclusively for music in my car, using pandora radio via headphone jack. Riding in silence is boring, but I really enjoyed the stability that this kernel provides. Waiting patiently with great anticipation if it can be done bbelos! :)
[Epic 4G Android Development] Mutiny32:
bbelos, I thank you and greatly appreciate your hard work. I must also applaud you for keeping all of your code publicly available on github.

I used Shadow Kernel shortly after rooting my phone in December. It was the only thing that fixed my GPS and wifi issues. Then, I started having bootlooping issues so I went with CM7 and all of its nightmares. CM9 alpha 4 fixed many problems but the GPS and wifi were still major issues for me. People over in the CM9 forum tried to help but no suggestions worked. Then, late last night, I saw that you had a version of Shadow that is compatible with CM9 alpha 4 so I had to try it. Yipeee!! GPS and wifi are smokin'. This Pup is way less nasty today ;-)

If voodoo sound is that important to you, you could always just buy the app. Viola, voodoo sound with shadow kernel.
[Epic 4G Android Development] Orion78:
Usually never had a problem with Shadow kernels, but my GPS is showing my location 2 miles from where I am..
[Epic 4G Android Development] KennyG123:
Did you go back to the stock kernel and check your GPS there?
[Epic 4G Android Development] Grommish:
When apps do that, that typically is a cell tower lock rather than your GPS. Tower locations tend to show 1900 meters
[Epic 4G Android Development] luna_c666:
Hmm..I was not aware that the premium version enabled these conrols even if the kernels themselves did not..thanks for the heads up. I guess that WOULD remedy my issues..nonetheless I'd still like to see this kernel have sound included (but, I guess it isn't as necessary to enable it within the kernel as I thought)
[Epic 4G Android Development] Orion78:
Yep im back on stock and its working fine on the stock kernel.. I tried to reflash thinking it was a bad flash but I still had the GPS issue.

[Epic 4G Android Development] nastypup:
I assume this is related to CM9 and not Shadow but I'm supposed to report strange things here, right? Because of the known bug of music and ringtones showing up, I was told to use media scan in the Dev Tools. Now, not only do my albums show up, but I have ~ 20 "albums" each containing 10 "songs" that don't play. What's really strange is that every name is in a language that looks like Italian or Latin! I can't find the location of these "albums" and would appreciate if anyone had an explanation. It's really messy to see these things when scrolling for an album.

[Epic 4G Android Development] bbelos:
Are you trying on windows or linux? I just tried it and once i check the box, it connects and my linux machine aquires a new network connection. I will have to test it later on windows, but it should do the same thing. A new connection should appear under "network connections".

Looking under dev tools -> media provider, I see 2 buttons. "Scan SD card" and "Insert 20 albums". Looks like you can change the number of "albums" but is there a chance you could have accidentally (or on purpose) clicked that other button? I'm not going to press it now but I assume it creates a bunch of empty sound files as some sort of test. Maybe I'll do 1 album and try and track down where it creates the files.
[Epic 4G Android Development] nimitz87:
running windows 7, what is the network called?

Chad
[Epic 4G Android Development] nastypup:
I know I pressed that button. I had no idea what I was doing. Anyway, I rebooted and ran the media scan without pushing the button and the files are gone. They definitely weren't sound files because they wouldn't play. And all of the names were definitely Italian.

[Epic 4G Android Development] XxLostSoulxX:
That's gotta suck man what exactly happened? and for GPS laggy it doesn't matter which kernel or rom you use GB has made GPS laggy. I noticed either kernel either rom same results. it works but then stops and then catches back up which is fast enough when you need to know where your going.
[Epic 4G Android Development] sonarchist:
Briefly: in windows 7 taskbar find + click the 'internet access icon,' then click 'Open Network and Sharing Center,' then you can 'Setup your Connection' by clicking 'Network Wireless Networks' where you may configure your WPA2 portable Wi-Fi hotspot settings (to conform w/ settings on your device: you name your own network a name of your choice)..................if your internet access icon still doesn't show your surrounding networks (including your own) then perhaps the issue is w/ your pc/device.............hope this helps.
[Epic 4G Android Development] nastypup:
So gingerbread messed with the GPS? I know stock did and that's why I rooted my phone. The only thing that made the GPS magnificent was Marcus' ACS ROM with Shadow. But I started having other problems which is why I started trying out other ROMs. The wifi with CM9 and Shadow is really fast. Averages ~ 15,000 whereas stock CM9 averaged ~ 5000. The GPS is better than stock CM9 but not what it was with Marcus' ROM when he worked at ACS.

heh, well at least it was on the way home. The Navigation portion of Maps didn't give me issues in the stock CM9. Just maps itself, which would run smooth til I turned on GPS and then it'd get super slow. Which made it difficult to even get to navigation.

Now with Shadowkernel installed, seems to run good with GPS on or off.

Don't always need to be doing turn by turn navigation to use Google Maps. Sometimes you'll just use it to get an estimate for how long it will take you to get from place to place, or search for something around you.

He was saying that Maps runs great with GPS off, but when just using Maps and he turns GPS on, it runs really slow.

K I ran this kernel for a couple of days and had to restore back to stock cm9 kernel.

I'm pretty sure its jjust my phone though because I haven't seen people report the problems I had.

For one, my phone was draining battery worst than alpha 1 :O but I left it alone because its a new kernel that needs to get used to my phone. But then my phone started overheating.

Charging? Overheat. Laying there? Overheat. On a phone call? Overheat.

I figure its because I had it set to OC, which would make sense, but no one else is complaining about heat...so I came back to stock because there was no point if I can't oc. I even UV the oc and it still overheated.

I also had my scheduler and governors set to stock values and then tried "no-op" and "smartassv2" still overheat.

Any ideas? I don't expect you to really know...but you've pulled through in the past lol
