I want v2.6.5 download link,its showing not found error when I try to download...
[Galaxy S II Original Android Development] Grimmy1st:
Heavy battery drains since 2.6.6 (using checkrom V4 & ondeandX & sio & UV)

e.g. over night (8 hours) 4-5 %, although no wakelocks & everything turned off (plane mode). Never had this before.

Hope 2.6.6i is better, cause Siyah is my favourite kernel!
[Galaxy S II Original Android Development] pikachu01:
Battery drains differently at different levels. 4-5% on airplane mode might be correct if you were at a certain battery level. Take note that battery levels isn't an exact science.
[Galaxy S II Original Android Development] veeruchinnu143:
I got the same problem.....that's y I need v2.6.5 dwnld link...
[Galaxy S II Original Android Development] pikachu01:
What governor are you using?

Older releases are deleted due to a bug in interactive governors that creates hung processes.

---------- Post added at 03:07 PM ---------- Previous post was at 03:02 PM ----------

Nope. It won't :)
[Galaxy S II Original Android Development] veeruchinnu143:
I don't use any governor infact I don't know what that means. But after I flashed v2.6.6 my battery drains fast. I have no problem with v2.6.5
[Galaxy S II Original Android Development] pikachu01:
Try installing Voltage Control and choose OndemandX or SmartassV2 instead in "Governors".

Also, it's a known issue that certain Wifi connections will drain more than normal. This will be fixed in 2.6.6i.

800mhz - default trothling greq

if i ll set smooth target to 0 what trotling freq i ll gave??? 1200??? if so - that great.

cant find any reason to go back from 2.6.4 - its a best for all (OC, bat life) and i cantsee any nasty lags what you talking about.... how i can see a nasty bag???
[Galaxy S II Original Android Development] XDA mark:
Been using SetCPU forever and just looked at Voltage Control. When I saw you can change I/O schedular I wanted to download it, at least to see if it was SIO or not (that was the best one, right?). But my question is, wouldn't having both SetCPU and installing Voltage Control cause conflicts between them?

Heavy battery drain after installing 2.6.6 , I will try using OndemandX or SmartassV2.

I hope it gets fixed in 2.6.6i

facebook chat is what causes the wakelocks on facebook , if you go offline when you have finished the chat session it wont have half as many wakelocks i found :-)

obvously the chat stays awake to keep checking for messages if you go offline after a chat session it defo helps :-) just press options in the chat section , the select go offline :-)
[Galaxy S II Original Android Development] Grimmy1st:
I know that and I know that there is nearly no 100 percent. But I didn't have this drain before. all settings and UV are the same.
[Galaxy S II Original Android Development] UpInTheAir:
Would only conflict if you have both to "apply on boot" or such.
[Galaxy S II Original Android Development] pikachu01:
SIO is the best. :)

Change it to SIO if it's not SIO. You can use my undervolt guide. In my sig "Android Optimization Tips". CTRL-F for undervolt.

Hmm, try another night again and see if you're still getting the same issue. It could be due to new apps you've installed previously as well? :/

i use set cpu to set cpu profiles

at the minute ive got voltage control installed and set to smartassv2 , done my undervolting and overclocking via voltage control too , and changed the sheduler to sio also via voltage control and saved settings for boot

i then have set cpu doing some profiles like screen off etc all the profiles in set cpu are also set to smartassv2

i dont have set cpu set at boot for voltage or cpu speeds its literally just to control my cpu via profiles

this should work ok shouldnt it? ie because set cpu is just doing profiles then there shouldnt be any conflicts should there??

thanks for any info
[Galaxy S II Original Android Development] marsexpress:
As advised earlier in this thread I switched from lulzactive to ondemandx on 2.6.6, scaling 200-1200 using setcpu. I then promptly enjoyed the best battery life I have ever had from my gs2 over 30 or so hours between charging, including 16 hours of admittedly near idling where the battery was draining at just 0.74% an hour! Brilliant I thinks, this is beyond awesome.

Put it on charge last night, wake up this morning and unplug, have a quick look at a couple of web pages, send a text message then lock it and leave it for 1 hour, come back to check it and I couldn't wake the phone up! **** it, back to the drawing board etc...
[Galaxy S II Original Android Development] pikachu01:
Wifi might be the one draining your battery. Wait for 2.6.6i :)
[Galaxy S II Original Android Development] gokhanmoral:
exactly. I am now testing wifi drain and I want to make sure that the wifidrain problem is gone.

until then, you can change wifi policy to turn the wifi off when the screen is off.

Anyone know why in cwm recovery i get error in every option related to sdcard "E:error mounting /sdcard/"
[Galaxy S II Original Android Development] Avolio:
Thanks Gökhan for this great kernel, i love it.. but sometimes my sgs2 dont wake up from the deepsleep.. i have read some post from other users they have the same problems.. im wait for the 2.6.6i ;)
[Galaxy S II Original Android Development] pikachu01:
You might be UVing too much, or your phone can't support 100MHz (if you're using the 100MHz step).
[Galaxy S II Original Android Development] Avolio:
Hm, but i dont changed my UVsettings in VC and in the previous version of siyah (2.6.3) i never had this problem with wakeup from the deepsleep.
[Galaxy S II Original Android Development] tolis626:
My SD insists on not mounting. :(
[Galaxy S II Original Android Development] :
I don't know if this will help, but you can try:

Install Chainfire CF KI3 42 kernel (the new one).

Reboot twice.

Install Siyah 1.7.8.b2.

Reboot twice.

Reboot into recovery, Power off the phone from recovery (last menu).

Power on.

I remember sometimes those issues had something to do with recovery not mounting something when restarting or similar on Nexus S.
[Galaxy S II Original Android Development] shrubber83:
me and other have experienced freeze and reboot on starting Titanium back... even both 1.7.7 and 1.7.8 version...
[Galaxy S II Original Android Development] Orka82:
Titanium Backup works great here. Try to clear the cache for Titanium Backup?

Mounting SD-card works too.

[Galaxy S II Original Android Development] gokhanmoral:
can you try to remove the following files and restart:

/data/.siyah/root-installed

/system/bin/su

/system/xbin/su

/system/app/Superuser.apk (or anything named similar)

you have to remove all of them with root explorer then restart.

I think your problem is related with su

[Galaxy S II Original Android Development] toxicOne:
Hi @ all,

I have heavy mistake with this Kernel

many reboots and heavy freeze!

... initframfs not support firmware xxKH3 !? :(

MFG
[Galaxy S II Original Android Development] ebliss:
Tried the above. Still didn't solve the problem. Device freezed when I ran titanium backup. I double-checked the 2 su files, Superuser.apk. All 3 are added after I installed the kernel. And /data/.siyah/root-installed is created.

And also, I have another error. The device either reboots or freeze after it reboots when the notification bar is showing "Media scanner running... (USB storage)". Sometimes it freezes on "Media scanning completed". Very random.
[Galaxy S II Original Android Development] incubus_fr:
I am not able to UC the CPU below 800mV with beta1/beta2. Instant freeze.

Just to let you know, there's no hurry ;)
[Galaxy S II Original Android Development] kwerdenker:
That the kernel supports UV doesn't mean your phone can take it. If it works, fine. If not, you'll have to keep buying another SGS2 until you find one which does ;)
[Galaxy S II Original Android Development] hayspat:
My device runs successful at 100Mhz@750mV with beta2. I think kernel does not source of your problem.

I have a question.

I never play games but I'm using my device as multimedia center ie watching 1080p videos. GPU undervolting is really help to save battery for me?
[Galaxy S II Original Android Development] jdmcivic:
it is working well with mine..
[Galaxy S II Original Android Development] chadouming:
did you tweaked ondemand governor between 1.7.7 and 1.7.8 ? Coz now it's lagging a bit.
[Galaxy S II Original Android Development] wanam:
Reverted to su2.3.6, why? is there any issue with the new one?
[Galaxy S II Original Android Development] gokhanmoral:
people were complaining about su not functioning...

it is not installed if the installed rom has another version anyway...
[Galaxy S II Original Android Development] gokhanmoral:
more laggy than before?

they are exactly the same as stock values in betas..
[Galaxy S II Original Android Development] chadouming:
probably just in my head xD

edit : Might be related with the time it take to switch from one step to another. 100 Mhz frequency never make my phone crash ( unless i undervolt it under 800 mhz ) and if i remove it, this lag is gone. Might be me who hate lag xD.
[Galaxy S II Original Android Development] incubus_fr:
I highly suppose my phone could take at least 775mV@100MHz as it can take 825mV@500MHz and 800mV@200MHz rock solid.

Someone else reported the same as me although his S2 runs 600mV@200MHz on Cyanogen. That's the reasons why I wonder and report my case :)
[Galaxy S II Original Android Development] jlevy73:
Try setting min @ 200. I bet the lag goes away :)
[Galaxy S II Original Android Development] chadouming:
having 500mhz @ 800mv doesnt mean your phone can take 100 @ lower than 800mv. My phone is rock solid with 500 Mhz @ 800Mv ( Even locked the phone to ths freq and make some bench ) and if i use anything lower than 800 Mhz. it lock almost instantly. 200 and 100 also lock instantly.

exactly what i did ^^

[Galaxy S II Original Android Development] :
Because if my phone needs to do something while the screen is off, I want it to happen as quickly as possible. Whether that's creating automated backups, transferring data or any other task which happens when the screen is off.

Changing the default behaviour of the ondemand governor will confuse users, as everywhere you look for a definition, it will indicate there is no screen off/suspend profile (for example the two explanation threads about governors linked in the first post).

I understand that I can manually add a screen off profile to mimic the screen on profile to negate this change if it is implemented (and I will), but I just feel changing the default ondemand governor in this way is a bad decision.
[Galaxy S II Original Android Development] The_MutenRoshi:
Heres my story:

Flashed 2.6.6 yesterday night, charged to 100%, unplugged before sleep. Wifi off, data off, no airplane mode. 7:30h latter my battery was at 96% (notjing special...) then I turned wifi on, and surf on web, read read read xda app forum, and 1h latter, (i.e. After 8:30h unplugged) my battery was at 67%...

Not as good as i espected.. =/

You have to wait 3 or more charge cycles before judging the battery. Did the same as you today but with 3g and wifi off. I think after an hour i had still around 80% left.

[Galaxy S II Original Android Development] mcarans:
SiyahKernel v2.6.6i changelog says:

"ondemand governor is merged with ondemandx and intellidemand governors. use this for having better battery life."

Thunderbolt! changes some ondemand parameters eg. I see in one of the init.d scripts:

# ==============================================================
# Ondemand
# ==============================================================
if [ -e /sys/devices/system/cpu/cpu0/cpufreq/ondemand/up_threshold ]; then
echo "85" > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/up_threshold;
#echo "1" > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/io_is_busy;
#echo "1" > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_down_factor;
echo "10000" > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate;
fi;

Does this mean Gokhan's v2.6.6i's ondemand governor changes and any tweaks he makes are being changed or overwritten by Thunderbolt! ?
[Galaxy S II Original Android Development] gokhanmoral:
let's hope this version solves battery drain & lockups that you had in 2.6.6.

I tested wifi for two days and there were two candidates. I did not feel much difference between them and I chose to release white list enabled one.

we'll see...
[Galaxy S II Original Android Development] stevehkim:
holy smokes 2.6.6i is super sonic. made me have a O face. if i use thinderbolt scripts GK is that geared more towards batt or performance?

[Galaxy S II Original Android Development] Hertz33:
Flashed the 2.2.6i and there is a problem right of the back. I connect my phone via USB to a PC and it doesnt recognize it. The phone is charging but before i was able to view the content of it and now nothing. I can enable USB Debugging but it's not the issue.
[Galaxy S II Original Android Development] stevehkim:
my phone is mounting to pc via usb is working fine.
[Galaxy S II Original Android Development] gokhanmoral:
one more thing about wifi drain:

our wifi chip has arp offloading and I let only unicast packets pass when the device is sleeping.

however, if you still have more drain when you are at work then you are at home the reason is that somebody scans the network (for security reasons or maybe a virus) or sends packets to your phone directly for some other reason. in that case, the only way to prevent that drain is to change wifi sleep method (wifi settings / advanced). in other words, if somebody is pinging your phone I have no solution for the drain caused by that.

I also increased wifi rx wakelock timeout value a little bit because I sometimes have latencies in some networks. it will prevent your device to sleep for 1 second if your device receives a unicast packet.
[Galaxy S II Original Android Development] Hertz33:
That's just strange. Never happend before with any version or any other kernel.

Also WAZE GPS refuses to connect to 3G when it works just fine while browsing.

Not a problem with WiFi though.
[Galaxy S II Original Android Development] stevehkim:
GK, do you recommend thunderbolt scripts for even more battery life? Or will this cause an issue? BTW donation sent boss.
[Galaxy S II Original Android Development] Hertz33:
Flashed the 2.6.6 back and problem solved.

Mos def the kernel's fault.
[Galaxy S II Original Android Development] gokhanmoral:
I cannot recommend something that I did not send :) however this doesn't mean that I recommend you not using it. Some parts of thunderbolt scripts are already in initramfs. I think pikachu01 has tested them and they work well but there is always a possibility that they can cause problems just as in 2.6.5.

But if they have no problems with the current version some tweaks can surely improve performance or battery life.

And thank you. :)

[Galaxy S II Original Android Development] pikachu01:
I just found out that some phones can't have too low levels of deepsleep in ThunderBolt! Are you using ThunderBolt! ?

I'll release a new version that fixes this.

Umm, use a browser in your PC. :) CTRL-F means 'Find in page'.

It's a wifi drain issue. Try 2.6.6i :)

Do you OC?

No, Gokhan's changes are internal, but it merges all the methods of other governors (ondemandX and intellidemand) into ondemand. The sysfs wouldn't change much, just that the extra sysfs are in ondemand itself.

It is geared for both :)

I recommend it :P But that's just me. I am still experimenting with the best values to cater to everyone's needs. Hence, some problems could still crop up, but I promise I'll fix it in a day or two. (or ASAP).
[Galaxy S II Original Android Development] cmd512:
v2.6.6i is throttling down as expected now with lulzactive, excellent! :)
[Galaxy S II Original Android Development] crm4:
Right. Forget about my usb problem.

In fact, my USB problem is not kernel related, and not even android related :confused:.

I just figured out that my 1 year daughter unpluged the usb cable that connect hub to pc. But hub power was still connected, so charging was ok.

Sneaky! :D
[Galaxy S II Original Android Development] thunderteaser:
Yep, not immediately though. I was using lulzactive, then switched to smartassV2, then ondemand and lulzactive again (of course I've applied the settings everytime). After a few seconds it hung while browsing the Market. I'm using Siyah 2.6.6 and Thunderbolt! 2.3.6. I'll let you come to the conclusion! :p
[Galaxy S II Original Android Development] droidphile:
I can confirm :)

May be, the interactive worker-threads which are started started when smarassV2 is active, is not stopped when switching to ondemand? Or the threads are not able to stop since cpu is not idling?

Gokhan knows better.
[Galaxy S II Original Android Development] Hertz33:
Aaargh its just me then with USB problem? Really weird, maybe its ROM related? Got no problem with 2.6.6 on the same ROM though. It's not really a big issue, just dont like when something not working properly.
[Galaxy S II Original Android Development] gokhanmoral:
it is a typo :) :register" should be unregister while stopping the governor. I do that a lot when I am in a hurry :)
