anyone here using L2TP vpn connections?

everytime I want to connect with L2TP after few minutes my phone hanges and I have to reboot it manually, I'm using siyah kernel 2.6.5 right now, before I upgrade I was using 2.6.1 on that version everytime I connected to L2TP after few minutes my phone reboots automatically, I've searched the whole forum but I found nothing, Can somebody help me please?

I'm on CheckRom v4 and I think its not rom related.
[Galaxy S II Original Android Development] supercurio:
Yes as gokhanmoral said that's a hardware limitation, becoming more noticeable on lower brightness levels.
[Galaxy S II Original Android Development] Fille84:
Any improvements when it comes to battery with 2.6.5?
[Galaxy S II Original Android Development] bnbasarir:
Gokhan, the new Linux source is out. It has some major improvements, especially CPU process scheduler improvements.

Any chances you might wanna use something from that...?
[Galaxy S II Original Android Development] omeryounos:
Installed it last night.. So no substantial data for multiple charge discharge cycle. But consumed only one percent overnight as well as one percent for a 10 min call. I have a feeling that it is one the best siyah kernel in terms of battery life.

Not using any mods and additional tweaks and scripts. Base is checkrom v4.

Hi guys,

I have got a problem.

I installed on my sgs2 miui's rom, but when I install this kernel, my screen show after some minutes some orizzontal line that in the superior part of the screen is easy to view in all colors, and in inferior part easy only on the white color.

Why I view this? Some fix?
[Galaxy S II Original Android Development] ercxar:
Did you UVed your gpu? I think the problem is that.
[Galaxy S II Original Android Development] arch-angel:
I'm using L2TP VPN connection on miui rom & siyah 2.6.5 never have problem like yours, so smooth here
[Galaxy S II Original Android Development] ercxar:
So you mean that it's kind of rom related problem? Cause a few people have this problem and their rom and kernels are various, I've tested stock rom and kernel and encountered same problem.
[Galaxy S II Original Android Development] arch-angel:
I'm not sure, I have used on original rom, cm7, miui langtang & miui rom. The last 3 roms all with siyah kernel and it works flawlessly
[Galaxy S II Original Android Development] PedroMRP:
SamFirmware have twitted this:

"Good Kernel = minimum battery utilization by Android System and Android OS in idle state. <10% combined after a day's moderate use."

What are your thoughts on this?
[Galaxy S II Original Android Development] incubus_fr:
If you get more than 10% of combined AOS and AS I have a simple fix for that:

Use your phone for some time and the Screen utilization will soon overcome them ;)

[Galaxy S II Original Android Development] pikachu01:
A setting in ThunderBolt! clashes with 2.6.5. I'll resolve this in a bit. For now, use 2.6.5 without ThunderBolt!. Sorry about that.

[Galaxy S II Original Android Development] cmd512:
Not using thunderbolt and 2.6.5 is running great.
[Galaxy S II Original Android Development] cooldfuzion:
To those that are using thunderbolt scripts and tweaks, is the performance better??
[Galaxy S II Original Android Development] pikachu01:
Part of the core ThunderBolt! scripts is already in Siyah. So, yes, performance is already better due to ThunderBolt! :P

The other part (and also some addons) are not in Siyah. Those can make it perform better, but sadly isn't compatible with 2.6.5 yet. I'll work to fix those ASAP.
[Galaxy S II Original Android Development] cooldfuzion:
Cool, thanks mate ;)
[Galaxy S II Original Android Development] pikachu01:
For v2.6.4, you can install ThunderBolt! and performance increase is not noticeable most of the time (as the core scripts are already in Siyah). The addition of the other addons/scripts could eek out ~5-10% of extra performance and 5-20% more battery life.

Yeah, which tasks hung is an issue I need to find out.

Screen off frequency for ... ? Which govnernor? You can do that with scripts:

For lulzactive:

echo "4" > /sys/devices/system/cpu/cpufreq/lulzactive/screen_off_min_step;

For smartassV2:

echo "200000" > /sys/devices/system/cpu/cpufreq/smartass/sleep_ideal_freq;

For ondemandX:

echo "200000" > /sys/devices/system/cpu/cpufreq/ondemandx/suspend_freq;

lulzactive and smartassV2 are largely the same with smartassV2 having an ideal frequency at screen off/on while lulzactive only has a frequency limit to screen off frequency.

Yeah, everything except the screenstate_scaling and the addons is implemented in Siyah. The 3G script won't work in SII. I'm not researching that for now. I'm focusing on performance/battery savings instead.

Those values are tweaked for battery. There is a setting in the smooth_target etc that I need to change for it to be smoother for ondemand type governors. As for lulzactive, it is smooth for me. Are you using an alternate setting to lulzactive?

You're using an app that cannot handle long lines. Jota text editor is fine for me :)

Try ondemandX with SIO instead?

Yeah, a few editors out there can't handle the long lines. So far Jota works well for me.

Yeah, I'll release a fix for 2.6.5 Siyah compatibility as soon as I figure out which tweaks are the culprit.

Yeah, only the core scripts. There are some that are not implemented.

Try ondemandX?
[Galaxy S II Original Android Development] Simuur:
2.6.5 has a bug ..

when you shut down the phone and plug it in to load it ..

after about 3 min the phone boots and asks for the pin ..

some users in a german forum also lost their imei/ their phone signal ...
[Galaxy S II Original Android Development] bgn9000:
Hello Guys, do you know why disableLog has disapeared into 2.6.4 ?

By the way, my best governor battery usage even in screen off is conservative... 0.16 %/h (airplane mode) :p

@Pikachu01

Holy ****,I didn't realize that the standard text editor/Script Manager text editor couldn't handle long scripts.But I don't think the problem lies there.See,I forgot one thing:

The fist time I tried pushing with adb,I pulled the script that appeared incomplete on my phone.Comparing it to the normal script from the zip on my pc,one was 32kb while the other was about 25kb.And it wasn't whole.Let's hope the problem lies with the text editor though.

Anyway,it works well enough as four scripts anyway. :p

By the way,what is the problem with 2.6.5?I've been using it since yesterday with Thunderbolt! and have had absolutely no problems.Contrary,it's a little faster than 2.6.4.

And one last question,what add-ons are you referring to?Except for the screenstate scaling one.

Thanks man! :)
[Galaxy S II Original Android Development] gh.rohit:
siyah 2.6.1

4:10hr screen time.....with 38min calling
[Galaxy S II Original Android Development] pikachu01:
What were you doing when you got the freezes? Which app?

Check BetterBatteryStats and see if there were any apps that were particularly draining?

---------- Post added at 01:13 AM ---------- Previous post was at 01:10 AM ----------

Which addons you didn't install? That can probably narrow down the issue for me.

The LMK, The bin and the libsqlite and the graphics addons.
[Galaxy S II Original Android Development] Moskvich:
I got some bug also. If i reboot the phone with charging plug in, the phone shut the SIM card. I perform the reboot without plug - OK.
[Galaxy S II Original Android Development] tolis626:
That ultimatesuperduperwowhellyeah kernel cleaning script is bull****,get over it.Either delete the init.d scripts with root explorer or a similar file manager,or just wipe cache and dalvik cache through recovery.Or both,whatever.You will rarely really need to wipe anything when flashing kernels.

Oh,will check them out then.I have only bothered myself using the standard Thunderbolt! script.Doesn't it also include the patched libsqlite though?

hey guys, how do these init.d scripts work anyway? cause i'm looking at those posted by fenomeno83 :http://xdaforums.com/showpost.php?p=18952013&postcount=8255

so do i just place the scripts i want in the init.d folder and reboot?

because after rebooting, my voltage control app does not show any changes.

as in, it seems like everything is back to default, including io scheduler and cpu gov.

Thanks.

I have an issue with wifi on both 2.6.4 and 2.6.5 in which when wifi is on my phone gets stuck on 200Mhz and does not go into deep sleep. with all the previous kernels this want the case. I noticed the wifi changes in the change log sooooo I know something was changed but what could be causing out to not allow me to go into deep sleep?
[Galaxy S II Original Android Development] remorema:
hey gokan. can you please add BT mouse support on next build?

my mighty mouse wont connect :(
[Galaxy S II Original Android Development] pikachu01:
Ah, if that's the case, it could be the screenstate_scaling script. Let me troubleshoot and release a new version if that's the case.

---------- Post added at 01:47 AM ---------- Previous post was at 01:45 AM ----------

Are you connected to a charger by any chance? Connecting to a charger will disable deep sleep.
[Galaxy S II Original Android Development] tolis626:
Yep,it must be the screenstate scaling add-on.I installed every single add-on(80Mb LMK) and I faced no freezes etc.So Thunderbolt! itself is ok. :)
[Galaxy S II Original Android Development] N6666661:
same here:(
[Galaxy S II Original Android Development] pikachu01:
I tried installing only the main system tweak and it still hangs. I'm guessing it has something to do with the network change.

2.6.5 isn't compatible with ThunderBolt!
[Galaxy S II Original Android Development] N6666661:
I dont use your script.

Siyah 2.6.5 is with Lulzacive (for me) : unstable, gives poor performances (Google earth, maps etc..), strange deep sleep %, etc...

I m sorry about this wrong comment but this is only the truth.
[Galaxy S II Original Android Development] tolis626:
Can you try splitting your script too?Just throwing out ideas here...
[Galaxy S II Original Android Development] pikachu01:
Try using ondemand or OndemandX?
[Galaxy S II Original Android Development] VFO:
No not on charger. Just running with wifi in my pocket.
[Galaxy S II Original Android Development] N6666661:
believe me or not with siyah 2.6.5 conservative governor gives me much better results than Lulzacive.

I dont think this is a normal behavior for Lulzactive.
[Galaxy S II Original Android Development] pikachu01:
Hey gokhan,

I think I know what's the issue here.

There are hung tasks in v2.6.5. Hence why enabling the hung_tasks_timeout will hang the phone. I see that there are 32768 hang task count as well as 10 warnings.Probably due to one of these changes?

lowered bus frequency threshold

put the throttling limits back (in tmu.c). this may prevent the phone shutting down on high load (such as games) but it will decrease the benchmark scores.

disabled rcu_fast_no_hz

Or even the wireless change (I disabled the wireless and it still hangs though, so not sure about this).

It's something you need to fix from your side. I am guessing that a high uptime will probably cripple the phone due to the amount of hung tasks.

---------- Post added at 03:05 AM ---------- Previous post was at 02:58 AM ----------

Flashing v2.6.4, I found that hung tasks timeout isn't enabled in the proc/sys/kernel. With that said, I'm guessing that it could be that enabling hung_tasks_timeout is the one that led to the discovery of hung tasks?

This is another theory. Siyah by itself already has a hung task problem. Enabling this led to the discovery of the problem.

I'm guessing that hung tasks aren't a big issue if your uptime isn't more than 300 hours? Or the hung tasks aren't tasks that consume resource?

Results for SpeedMod / Phenomenal / void / N.E.A.K. / Siyah / stock kernels

Everything is specific to my phone, my "normal" usage and my home location. Most values are exact results, but some are rounded. I usually have wifi, synch (three email accounts, calendar and news), Google Talk and Skype on.

For all custom kernels, I was running on Frankenstein XWKL1 ROM (Modem: XXKL1).

For stock kernels, I was running on the corresponding stock ROM.

Always using the Samsung's standard / stock 1650mAh battery.

Added my battery test results for Siyah v2.6.4 - completely default settings without any customizations/optimizations.

Here are my current results:

Benchmarks

Battery stats

Siyah v2.6.4 is not the best kernel regarding battery life in mixed usage for me (on my phone with my "normal" usage).

But I have to say that I only tested it with completely default settings. So nothing was customized / optimized (e.g. no UV).

And this is the big advantage of Siyah kernel: It is very configurable.

Now flashing and testing Siyah v2.6.5. I will post my results as soon as my tests are finished.

Hmmh, seem to me an Entropy answer if you know what i meen hmm ? He is jusy as saying testing kernels out of the box with his own usage as stated. Nothing wrong for me and I respect the work taking it just for what it is as I respect yours and thank you for it.

[Galaxy S II Original Android Development] It_ler:
Thanks Namoi.

So, some users understand what I am doing ... and what not.

I respect everyone who does feel like AndreiLux.

I know that even if I always state that these tests and results are only for me - on my phone, with my apps, in my region, for my "normal" usage, and the same kernel will have different results on other phones, some users really take these numbers as "facts" to choose their kernel.

Maybe users who are bothered by my result posts can better ignore my posted results when recognizing that some other users are interested in these test results and are inspired to try and flash the one or the other kernel.

So that's my real aim:

Everyone ... just look for an interesting kernel/ROM/Modem or whatever and just try and flash it to your phone.

Test it for a while and decide by yourself, if it is good for you or just look for something else and keep trying/testing ... till you have found the "best" thing for you and your phone ;-)

P.S.:

Don't forget to make a backup before flashing anything to your phone. Just to be on the safe side.
[Galaxy S II Original Android Development] AndreiLux:
As I have said previously, do what you want to do, but then do it in a separate thread. The fact that you plastered your enormous benchmark post 33 times in the last month all over the different threads.

You just said it yourself. What you are doing is an opinionated testing and by trying to format your post well and pretty, you come off as an informed user who should know what he is talking about. XDA is supposed to be a technical forum where technical discussions are being held, and part of discussions is also dismissing false claims. What I am doing is merely trying to inform people that you are spreading misinformation, and if you have a problem with that, then that's a different issue. I understand what you are doing, you're just doing it and portraying it in the wrong way.

I have much higher battery drain with 2.6.5 compared to the previous 2.6.4 still trying to figure out what causing the problem. Had a look in CPU Spy and where the use of 1200Mhz was before at 1% it is now at 6%, lulzactive seems to have a problem too with deep sleep.

After a few sec its working again but a few sec more it makes a reboot.

When it's done I've to reboot manually again, because some laggy probs then.

This I had maybe 4 times in last 2 weeks and nothing special done before.

It's an normal wakeup from deep sleep, I think.
