Yeah, tried with and without Trickster. Made no difference. Still this kernel is smooth and RRs are gone. Well until I just jinxed myself probably.
[T-Mobile Samsung Galaxy S II SGH-T989] ryh2013:
I've noticed intellidemand completely disables the second core, and has problems when waking up the device.
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
Try Hyper, I'm having good luck with that one again on this most recent version.
[T-Mobile Samsung Galaxy S II SGH-T989] ryh2013:
I'll give it a try.
[T-Mobile Samsung Galaxy S II SGH-T989] fenrry:
So far I'm playing around, and I'm quite happy, just wondering, any way to modify the sensitivity for the Sweep2Wake?, also, in the Peformance part, I was using Intellidemand with SIO...my Core#1 was 0 all the time, not that my phone was slow, yet I noticed a few things in the animations, coming back to the main screen from the drawer and so on, not huge things, again, the phone works really nice.

Btw, any recommendation for Performance?, Governor, I/O, Dalvik settings?, I'm getting around 5 hours of battery, not like this phone was any marvel in that matter.

Thanks! :)
[T-Mobile Samsung Galaxy S II SGH-T989] Emmanuel U:
No feature in this kernel completely disables a core...cores are hotplugged based off of CPU load regardless of governor as it is tasked by a separate module
[T-Mobile Samsung Galaxy S II SGH-T989] dennis96411:
The new Intellidemand is a bit clunky compared to the old one. System responds a little slower, and I can notice lag in the UI. I started playing Modern Combat 4 and it was stuttering pretty badly. I switched over to Hyper and the stuttering was gone.
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
Alright Hyper got laggy on me also so now on to Performance. You can't go wrong with that one and battery consumption isn't all that different anyway.

Do you wasn't slimbugreport if were using kernel with 4.4.4 slimkat? It's the easiest way to send log is why I ask, because I'm lazy
[T-Mobile Samsung Galaxy S II SGH-T989] dennis96411:
Strangely enough, my maximum CPU frequency stuck after switching from Intellidemand.
[T-Mobile Samsung Galaxy S II SGH-T989] Emmanuel U:
Update!

Minor update today, just a few bug fixes. Enjoy!
[T-Mobile Samsung Galaxy S II SGH-T989] mr_stevey:
so, yeah...

v007 is amazing, wanted to write this up now since i saw v008 is up and i can play with that later today. running on 19 hours with 33% battery left on the latest carbonrom; i have moderate use and some periods of heavy use. not bad at all and much better than v006. overall, VERY impressed with your work, keep the good stuff flowing.
[T-Mobile Samsung Galaxy S II SGH-T989] Tornado15550:
I agree. v007 is simply amazing. It's very smooth. My battery itself is in need of replacement so I can't say much about the battery life but I'm sure it's increased thanks to this kernel. Great job, Emmanuel!!
[T-Mobile Samsung Galaxy S II SGH-T989] bmg002:
I'm currently running v7 and it is super smooth but I'm not getting deep sleep. Keep getting a wake lock of msm_serial_hs_dma that seems to run from when I unplug until the battery is flat. Going to reboot now and see if that allows me to deep sleep on v7.
[T-Mobile Samsung Galaxy S II SGH-T989] gulbir101:
what settings are you running? if you dont mind me asking.
[T-Mobile Samsung Galaxy S II SGH-T989] mr_stevey:
yeah, no problem. i run badass/deadline clocked at 9600-1350000, tcp set to westwood.
[T-Mobile Samsung Galaxy S II SGH-T989] Emmanuel U:
Intellidemand and SIO under the same settings as yours works wonders as well...try it out sometime and see which one fits ya better
[T-Mobile Samsung Galaxy S II SGH-T989] HipHopAnonymous3:
Diggin v008. Runnin buttery smooth on soupysoup's latest beanstalk 4.4.4 running intellidemand/sio/westwood/96-1728. Thank you for your work sir :)
[T-Mobile Samsung Galaxy S II SGH-T989] dennis96411:
I'm using FIFO. Is SIO better?
[T-Mobile Samsung Galaxy S II SGH-T989] bmg002:
a good read on governors and schedulers and such:

http://xdaforums.com/galaxy-s2/general/ref-kernel-governors-modules-o-t1369817

I am pretty sure that picking a governor and scheduler is kinda user and use specific. I don't think there is a "best for every situation" one. Like performance works awesome as a governor but eats your battery like crazy. Powersave will keep your battery nice but it does so by keeping the cores at the min values (IIRC). And as for schedulers, I think it all depends on how much multitasking you do. noop I think is good if you try to keep multitasking to a minimum while fifo is good if you do a lot of multitasking (don't quote me on that though... I may have that wrong).

On a side note, I'm still not deep sleeping on V008. And I'm still seeing that wake lock (the kernel wake lock msm_serial_hs_dma). It seems to run almost as long as my phone has been on. Strangely I don't see a vbus_present wakelock even while charging my phone?

Quick bit of snooping shows that the msm_serial_hs_dma wakelock is related to bluetooth. Think you could throw this fix into the kernel:

http://xdaforums.com/showthread.php?t=1786981

Find config.xml in overlay/frameworks/base/core/res/res/values and change or add in

<boolname="config_bluetooth_adapter_quick_switch "> false</bool>

Also, if somebody else could nab a wakelock checking app (such as betterbatterystats) and check for the msm_serial_hs_dma wakelock, I would appreciate it. If nobody else is seeing it, it is likely a ROM issue and thus I should jump from my current 4.4.2 hellkat to a 4.4.4 something (dunno which yet).

Otherwise loving the kernel. Using the stock HellKat kernel (diablo), my boot times were nearly 3 minutes (with all the apps I have installed and tweaks I put on like enable mass_storage and use the SD card for /data). With V008 I'm averaging 1 minute 30 seconds.

Awesome work :)
[T-Mobile Samsung Galaxy S II SGH-T989] mr_stevey:
will give it a shot, man! thanks for the heads up!
[T-Mobile Samsung Galaxy S II SGH-T989] HipHopAnonymous3:
Haven't noticed any unusual drainage. I'll run BBS+ today and let ya know if I see anything tonight
[T-Mobile Samsung Galaxy S II SGH-T989] bmg002:
Thanks a bunch. In a way I'm hoping that you notice the same thing (and thus it MAY be a kernel related thing), but I am also hoping you don't as that means it is ROM related and it gives me a better excuse to upgrade to 4.4.4. I'm wanting to upgrade, I just am on call with work all the time so I don't have a good time to do an upgrade... that and I don't want to have to reinstall all of my apps LOL.
[T-Mobile Samsung Galaxy S II SGH-T989] stanguay:
Same problem for me, with Beanstatk

When I turn Off the Bluetooth I don't have the wakelock on V008.

I return to v005 and I don't wakelock even with Bluetooth On. V005 fix me.

Hope this can help
[T-Mobile Samsung Galaxy S II SGH-T989] HipHopAnonymous3:
I hear that. Never gets any easier restoring all your apps/settings/data. No wakelock over here with bluetooth turned off all day. I'll turn it on for a few hours and see if it pops up.

The only thing I've noticed is when my phone's asleep and I get an incoming call, the phone will ring and vibrate as usual, but the screen doesn't kick on for about 6 or 7 seconds (seems to vary). I'm going to wipe everything and keep kernel stock to see if issue is kernel or ROM related. Beanstalk 4.4.4 by soupysoup is excellent btw.

Update:

Confirmed msm_serial_hs_dma wakelock is present with bluetooth turned on. No wakelock when bluetooth is turned off though.
[T-Mobile Samsung Galaxy S II SGH-T989] bmg002:
That is what I noticed too. Also noticed that deep sleep seems to be back now too. Loving the kernel but like Bluetooth... Tough call
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
IDK about Bluetooth as I don't use it but this kernel is awesome with Slimkat. No RRs yet and fantastic battery life. Definitely stable for me at least.
[T-Mobile Samsung Galaxy S II SGH-T989] Emmanuel U:
I'll look into it
[T-Mobile Samsung Galaxy S II SGH-T989] HipHopAnonymous3:
Thanks man. We appreciate it. BTW, delayed incoming call is not kernel related.
[T-Mobile Samsung Galaxy S II SGH-T989] ricthot:
I experienced this issue as well but not just with incoming calls... Whenever the phone entered deep sleep, it sometimes took ages for the screen to come up. I don't think its kernel related either as I had this issue with the stock Pac Rom kernel as well....

I'm now using straight Official CM11 with stock CM kernel and have not had this issue once...
[T-Mobile Samsung Galaxy S II SGH-T989] raptor170:
Wild v8 working great here with pa alpha 3
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
Any idea why the second core is so hard to control? No kernel app I've tried except for Kernel Tweaker has worked, and even then 96/1512 comes back after deep sleep.
[T-Mobile Samsung Galaxy S II SGH-T989] ryh2013:
Kernel Tuner works for me
[T-Mobile Samsung Galaxy S II SGH-T989] raptor170:
Can't get deep sleep with v8 and slimkat

Edit: she's sleeping now, turned off keep awake for playstore
[T-Mobile Samsung Galaxy S II SGH-T989] bmg002:
Thanks for looking into it. Just from my playing around, if I set my low speed to 96, I get ALMOST the same battery life with bluetooth on or off. It is slightly better with bluetooth off but is very similar with or without that wakelock.

This is so far my favorite kernel. I like the extra memory (although I need to tweak some things as a lot of that gets eaten up on boot) and being able to drop my low speed to 96 is awesome.

I've also read about others getting over a day out of this Kernel. I get on average 10 hours with my setup. Which works for me (I have a spare battery and am rarely away from a charging location for 20 hours). With Diablo, I would get about 8 hours average.

Thanks for keeping this device alive :)
[T-Mobile Samsung Galaxy S II SGH-T989] mr_stevey:

I had same thing when phonecall came in, couldn't answer/reject etc. Never showed up, not sure ROM or kernel related, running slimkat with 96min..... Maybe running at 96 causing this
[T-Mobile Samsung Galaxy S II SGH-T989] ryh2013:
What's your governor?
[T-Mobile Samsung Galaxy S II SGH-T989] raptor170:
Intellidemand/noop

[T-Mobile Samsung Galaxy S II SGH-T989] Emmanuel U:

[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
This happening to me too on Slim. I've tried Ondemand, Intellidemand, Hyper, Samsung and Interactive. OC and no OC. SIO, Noop and BFQ schedulers.
[T-Mobile Samsung Galaxy S II SGH-T989] dennis96411:
Don't take my word for it, but I seemed to get a lot of reboots too when I had zRAM on. Can someone see if that's a cause?
[T-Mobile Samsung Galaxy S II SGH-T989] chris4824:
I left it at default. Also tried changing it badass, ondemand, and others.. They all done the same.. I'm lost.. Not sure if it's a bad build so recompiling and try again..
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
Don't ever use Zram, there's a reason CM got rid of it. Causes more problems than it solves.
[T-Mobile Samsung Galaxy S II SGH-T989] raptor170:
Strange I've had no RR with wild and slim, with intellidemand and sio. Only the dialer not showing up when receiving a call the one time. Our devices all have a mind of their own
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
Our device has more of a mind than I do at this point, this thing is driving me nuts!
[T-Mobile Samsung Galaxy S II SGH-T989] chris4824:
So I recompiled Validus 6.1 and still wild kernel will not work with the new source.. Not sure if wild kernel needs updating so I'll let Emmanuel U look at it and maybe he can think of something.. I know that Liquid Smooth also had problems with freezing and rebooting when using wild kernel as a base for the kernel..
[T-Mobile Samsung Galaxy S II SGH-T989] I Am The Frost:
Everyone running builds made since about Tuesday will not work with third party kernels. This is due to CM and their need to screw everything up. They had a mass of kernel changes. As far as I know, the Hercules is "waiting on unfinished jobs". An update will solve it, when Cm is done screwing around.
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
Well figures as much. Why has KK been so hard for CM to stabilize? This kind of thing didn't happen with ICS or JB.
[T-Mobile Samsung Galaxy S II SGH-T989] I Am The Frost:
I honestly don't know what they are doing with it. Other than to say that they have a habit of fixing things that are not broke. This is why I don't include a kernel in my Carbon builds. Just flat out frustrating ?. With jellybean their change of choice was ramdisk. Who knows what it is this time.
[T-Mobile Samsung Galaxy S II SGH-T989] wvuravens-fan:
Honestly for the first time I stop updating my phone to the latest version. I am running frosted carbon 7-14 and wild v3. This combo is perfect, everything is working.
[T-Mobile Samsung Galaxy S II SGH-T989] mr_stevey:
is lulzactive still broken? i've never had luck with it, but when i updated to v008, my phone kept rebooting until i had the (lucky) chance of switching to badass from lulzactive. since lulzactive is selected by default, it's a little annoying because trickster doesn't always process the change without a reboot occurring. is there a way to prevent this or something?

---------- Post added at 12:55 PM ---------- Previous post was at 12:54 PM ----------

i'm with you on that. the more frequently i update the more bugs i have and that means more headaches and a less functioning phone.

wlan_rx_wake on Wild 008

I've been using Wild 008 since it was released and generaly find it very good, but occasionally I am getting a wlan_rx_wake wakelock that keeps the phone awake, and I don't remember that being an issue with previous versions.
[T-Mobile Samsung Galaxy S II SGH-T989] bmg002:
I get those too but I don't think it is an issue... 15 min of wake lock wlan_rx_wake in 6 hours for me

Anyone else getting random reboots with v8 on pa beta2
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
It's been mentioned elsewhere but I guess bears repeating. If you use this kernel with ROMs made after July you are going to have problems due to all the changes by CM which is a base for about any ROM around. This kernel will need an update to be stable with new releases.
[T-Mobile Samsung Galaxy S II SGH-T989] raptor170:
That's def worth the mention, I had ran it with liquid to see if data fix, and within an hour had few RR and even with phone off I couldnt charge phone, and when trying to charge with phone on it would sod, works great on ROMs before august

[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:

I'm having trouble running the latest PA with this kernel. Nothing but RR, but also a dirty flash. Anybody clean flash PA with this kernel? Anybody able to get PA to run with this?
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
You're SOL, go with stock until there's a kernel update. Runs fine without a custom kernel anyway, only had on RR and that was on the Performance governor which pushes the CPU hard. If you want to still use Wild!, you'll have to revert to PA builds from last month or earlier.
[T-Mobile Samsung Galaxy S II SGH-T989] suaverc118:
Yup. Was just testing. I reflashed PA beta 2 over with no issues.

Same thing to cause the RR in cm10 way back when. Hope this helps Emmanuel U. Didn't reply earlier because I wanted to make sure. This kernel has managed to eliminate the RR on the s4 running PA Beta2.

Hercules is still affected with newest PA. 4.5 alpha 3 works though.
[T-Mobile Samsung Galaxy S II SGH-T989] Emmanuel U:
Really minor update

This update is for people who like to update your roms :P There was a major ramdisk change upstream that it seems ROMs are switching too....I personally hope not permanently because a lot of it is dirty hacking. But hey if you want to use WildKernel with any of the recent updates, use the newram.zip otherwise stick to regular 009.
[T-Mobile Samsung Galaxy S II SGH-T989] luxkore:
Okay, I probably did something wrong, but I'm getting a boot loop for PA 4.5 beta2 right after flashing.

I have a Titanium Backup, though, so I'll try a clean flash in a minute.

one more thing i wanna throw at you. do you have full sd card support? an issue i was having before was that my sd card was not being read and when i switched to PA, it started to work.
[T-Mobile Samsung Galaxy S II SGH-T989] ayr0:
I've been playing with it now for almost a week. With one, exception, it the 9/24 nightly and WildKernel v9.2 has been a great combo.

The exception: I was talking with my father the other day, and my phone randomly just shut off. I have no idea why. The battery was around 60%. I eventually got the phone to boot again. I turned off overclocking on the cpu as I think that might have been the culprit. It is the first and only time I've ever had that experience.

I have a 16GB microsd card in my phone that works fine. I'm not sure what you mean by "full support", but I've not had a problem accessing my sd card. I can read and write to it.

I have heard that the Cyanogenmod build put together by Sultanxda is really stable. If this ROM+Kernel doesn't work out, you might consider giving that a try. The only caveat, you can't use any other kernel with his build. It is tweaked in such a way that only his stock kernel will work.
