Strange problem, random no service

I've been having this odd little problem very occasionally (rarely) for the past few weeks. Sometimes, apparently randomly (at least I haven't been able to see any common thread between the times it has happened), my phone gets itself into a state where it says there is no service - none at all, including no emergency calls - despite the fact I know there is good coverage where I am, and just a moment ago it was working fine.

The only thing that fixes is to shut down the phone and take the battery out for a few minutes and then start up again. Turning flight mode on and off doesn't work, and even a normal reboot (without shutdown and battery out) still exhibits the same problem.

I think I've only seen this since I've been on the K2-18 test builds, but I don't really know if this is kernel related. I haven't tried other kernels to see because at the moment it happens very rarely (in the past three or four weeks I've had it happen four times). I'm not yet on the latest test build, but I'm going to update shortly.

So.. I was just really wondering if anyone else has experienced the same thing?
[Galaxy S II Original Android Development] fidorulz:
Test 15 is looking good so far in terms of speed and overall scores. Battery tests to come
[Galaxy S II Original Android Development] jsompis:
Got no deep sleep issue with test15.
[Galaxy S II Original Android Development] aqualeris:
Had this problem a while ago as well. For me rebooting and toggling with airplane mode works most of the time though. Ever since I reflashed a new ROM with the same modem and things seem to be better now. Try reflashing your modem.
[Galaxy S II Original Android Development] catmat:
Confirm. No deep sleep, stock KK5. Revert to test 12.
[Galaxy S II Original Android Development] zekurosu:
downloaded...will be using test 15 n report back later....

thanks hardcore for this awsome kernel

No Deep Sleep problem here with T15.

Deep sleep is fine for me too on check rom 4
[Galaxy S II Original Android Development] general forceps:
'Got no deep sleep issue' can be understood both ways, folks.

Hard to figure out if the issue exists/persists or not by looking at the comments.

Let's make it simpler, thanks
[Galaxy S II Original Android Development] dzontra11:
Deep sleep problem..nooooo

Deep Sleep works fine here in t15.

Better? :)
[Galaxy S II Original Android Development] Incarniac:
Thanks. As it happens I'v just flashed modem KL1 to see what it's like :)
[Galaxy S II Original Android Development] zekurosu:
test 15 doesnt enter deep sleep mode at all for me...95% in 200Mhz and draining my battery
[Galaxy S II Original Android Development] crash_194:
No deep sleep for me either on K18-test15 and its raping my battery...?!
[Galaxy S II Original Android Development] AndroidGX:
I like the term 'raping' like you said because I have the same feeling on this test15 actually :D

Performances on test15 is better than test13, but still can't defeat my 4850 Quadrant score that I hit on test12.

Thinking to revert to test12 which is still the best, definitely.
[Galaxy S II Original Android Development] Darclite:
Deep sleep issue with test 15 on ki3 here :) back to 13 I guess!
[Galaxy S II Original Android Development] crash_194:
Lol ;-) A battery drainage issue with a Speedmod kernel is very obvious as so far for me they have been pretty amazing on battery life. Totally agree performance wise though, test 15 is lovely, 13 was good, but for me 15's performance is the slickest yet. I always feel like a good indicator is the snappyness of touchwiz, and with test 15 is almost as smooth as htc sense (which I have always found smoother, quicker and less jerky than touchwiz).

I'm back to 13 for now as coupled with the Rom Kitchen optimized kk5 rom the phone is awesome at the minute.
[Galaxy S II Original Android Development] apeiron6:
Quadrant benchmark is not good reference point. Try other benchmarks. I think that smoothness, stability and battery life should be a good reference point
[Galaxy S II Original Android Development] Hilmesh:
Deep sleep issue here also. I am KJ3. How to solve? Or should I revert back to test -13.
[Galaxy S II Original Android Development] celeritykid:
Noticed that test 15 has touch screen lag. Is there anyone else with that problem?
[Galaxy S II Original Android Development] hardcore:
There is no 'deep sleep issue' for me on test-15 there should not be any difference between it and earlier versions.

If you see *any* deep sleep time at all in cpuspy, it means deep sleep is WORKING and you have NO ISSUE.

The phone will NOT deep sleep if plugged into USB or charging. It will also not deep sleep if the screen is on.

And if your phone is really not getting into deep sleep, then post a screenshot of cpuspy and also state the conditions (wifi on/off, 3g data on/off, rom used, setcpu used or not, any changes to the governor, any startup scripts used, etc.).
[Galaxy S II Original Android Development] hardcore:
This means that deep sleep is working and there is NO PROBLEM.
[Galaxy S II Original Android Development] Jonjungle:
Lol if that was a deep sleep problem hell yeah! keep it up Hardcore hehehe! 97% is fantastic :D

[Galaxy S II Original Android Development] SaneinOne:
Sorry, more meant resetting timers.
[Galaxy S II Original Android Development] y17dt:
yes, immediately after reboot I resetted timers, Killed all Tasks, switched off the Display and after about 5 mins Started CpuSpy and took the screenshot.

EDIT: Now flashed Test 13 (same Method) and I can get DeepSlepp within a few seconds... Everything is fine on Test13 but issues on Test15 :confused:

[Galaxy S II Original Android Development] crash_194:
I'm using the rom kitchen optimised kk5 rom and I can't get deep sleep with test 15. I can get deep sleep fine with test 13 but as soon as I flash 15 I can't get it at all. Flash straight back to 13 and all is well. We had this problem a few builds ago didn't we with another version. Did we ever track down what actually caused it?
[Galaxy S II Original Android Development] henriquesb:
Those with deep sleep issues, are you using Wifi with sleep policy set to Never, or using Wifi for some hours?

Maybe the wifi wakelock timeout interferes with some modems... :/
[Galaxy S II Original Android Development] crash_194:
My wifi is set to sleep when the screen turns off but my wifi is never on unless I'm somewhere I want to use it as I don't have wifi at home. Good idea though, and thanks for the help!
[Galaxy S II Original Android Development] Darclite:
My cpu spy looked exactly along the lines of y17dt's screenshot. My setup is the frankenstein ki3 rom from intratechs thread with the test 15 speedmod kernel, nothing more or less. My wifi sleep policy is 'never while plugged in' and i have rebooted, reflashed and reset the timers. As soon as i reflashed test13 deep sleep was instantly visible on the cpu spy app. Never had any other deep sleep issues with the other kernels.
[Galaxy S II Original Android Development] ryu2964:
Hi hardcore

really hope you can add screen color options features in your kernel

to save my phone , it's too blue:(
[Galaxy S II Original Android Development] gtda:
mines too blue aswell

but id rather see colour banding fixed first
[Galaxy S II Original Android Development] AndroidGX:
Seriously, BLN is a joke !

This app, once activated, drains battery like almost 20% in 5 hours on sleep (tested this last night).

Trust me, it's better to wake up the phone for 5 sec to check notifications manually ;)
[Galaxy S II Original Android Development] gil80:
@hardcore

Hi.

I wanted to know why did you choose conservative governor instead of ondemand?

It seems that ondemand is a better option in smoothness when I used MIUI on SGS I.
[Galaxy S II Original Android Development] AndroidGX:
It's already "ondemand" on my device, and I didn't touched anything :confused:
[Galaxy S II Original Android Development] xinfinityoO:
which app did u use to set the governors..setcpu doesnt work !!!
[Galaxy S II Original Android Development] AndroidGX:
What message do you get with SetCPU ? because I'am using latest version 2.2.4, just tried to switch between governors and seems working like a charm for me.

Anyway I just uninstalled it again as it's useless with this kernel :)
[Galaxy S II Original Android Development] meroupow:
I had a strange stuttering and freezes in video playback when using my external SD (16 GB class 6), I never had before using speedmod kernel.

I checked and the readahead value set by speedmod of 4096 is the reason.

I put 128, 1024 and it was fine.

then 2048 and 4096 would cause stuttering and 8192 would be fine again.

The read speed is always 20Mb/s for this micro SD whatever this readahead value is.

The internal memory is not affected by this behaviour.

Probably it is only with some micro SD, because I didn't see many people complain.

Would it be a possibility to change this value from recovery menu?
[Galaxy S II Original Android Development] hardcore:
Must be something else that set your read ahead value because speedmod uses 512kb.

Edit: found a big bug: turned off Wifi, turned back on and it does not connect. After a min or two it suddenly connects! Before it was instant and did not play games with me ;)

@hardcore: can you integrate the fix you made on 18 test2 to your next version? It's the only version that prevents long and hd videos for youtube to stutter when the video reaches around 50% :)

Cheers!
[Galaxy S II Original Android Development] paulyluca:
Wifi is working fine for me. I am using test 15 and same Rom as you.
[Galaxy S II Original Android Development] hardcore:
5 minutes is too short. The phone could still be re-indexing your photos or something like that. Give it at least 30 mins to an hour before checking.

Also, if you use betterbatterystats you can see what is holding the wakelock.
[Galaxy S II Original Android Development] Pfeffernuss:
KK5 Kitchen Rom, test 15 working just fine, both deep sleep and Wifi, no problems.
[Galaxy S II Original Android Development] nikzDHD:
Also using optimised kitchen rom kk5 and no deep sleep issues, one thing I can say is that this new version seems fast faster than previous. Will test battery over the weekend.

Reflashed the test15 kernel earlier in the night and went off and played some BF3, now around 3 hours later i can say i still have the deep sleep issue. My wifi was set to off this time and betterbatterystats didnt show anything causing a wakelock. Maybe its mis-reporting and i am still getting deepsleep, either way its draining the battery :( once again back to the stellar test13!

How long did you wait before checking? It can take half an hour to re index all your images.

Results for SpeedMod / void / 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 XWKK5 ROM.

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

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

Running void.echo kernel, I used the default settings, and only enabled „Auto CPU UV on boot“.

Here are my current results:

Benchmarks

Battery stats

So, Test15 is not the best kernel for me (on my phone and with my "normal" usage).

I will go back to Test12 and stay a while on XWKK5 ROM, as it is very stable on my phone.
