Re: [KERNEL][CM10/CM10.1/ICS - OLD/NEW BL][010 - 2013/01/19] Kowalski Kernel

I had a fatal error just now where my car charger disconnected (it was loose anyway) and the battery was draining like a countdown. It was at 16 percent I think, then dropped down to zero in a matter of seconds and the phone wanted to shut down. It froze while shutting down however and a quick battery pull restarted the phone (without using power button). I was able to get a proc/last_kmsg log here http://db.tt/Zj0X0XAU.

I'm using tonyp's PA 2.5 on new bootloader. 010 kowalski kernel. Swap enabled, zram 18%, interactive governor, row i/o.. Anything else is default settings I think.
[LG Optimus 2x] MetaIIica:

Guys i'm aware of the wifi problem. It kicked in because of the unified driver and yesterday we tested and developed a fix. In a few I'll upload a set of wifi modules that will patch the wireless driver ;)

Re: [KERNEL][CM10/CM10.1/ICS - OLD/NEW BL][010 - 2013/01/19] Kowalski Kernel

Yeah seems perfect to me... Those are all partial wake locks used by apps and kernel to receive calls, emails, ring the alarm, etc...
[LG Optimus 2x] my_dnl:
With old bootloader you have slow charge bug: shutdown your phone, plug the charger and start your phone to have normal charge.

When you unplug the charger probabilly phone doesn't enter in deep sleep and have random 1GHz dump: restart your phone to have normal battery drain.

At least for me it works: give it a try.

Re: [KERNEL][CM10/CM10.1/ICS - OLD/NEW BL][010 - 2013/01/19] Kowalski Kernel

Oh my, ain't that a lovely crash :D

Your battery charger code crashed badly and told the kernel/system that you didn't have a battery anymore. Nasty.

Yeah they should work fine on ics. Those functions are handled in user space :)
[LG Optimus 2x] vkk178:
Can we have different settings for swap and zram ? I mean both swap and zram use the vm.swappiness setting for swappyness config . So I can use either use both swap and Zram at the same swapiness level or turn of one of them and use the other . It would be great if I could use be able to use zram and use a file swap with swappiness = 0 ( just incase the device totally runs out of RAM) . I can think of using some build .prop setting which does some indirection .. Some thing like zram.swappiness.flag = vm.swappiness and swap.swappiness.flag = vm.swappiness .. Just my 2 cents

Wifi Update

Guys i uploaded to my dev-host folder a new set of wifi modules, in the subfolder "wifi". They're marked as version 010p1 and will fix the wifi problems you're having. It's been tested since yesterday on 10, 10.1 and ICS. The only "known problem" is that on ICS when you install one of these mods you will have to clear dalvik/cache to make it work as it should. Nothing major though.

Fast PSP (kernel default) -> kowalski-kernel-010p1-default-module.zip

Full PSP -> kowalski-kernel-010p1-psp-module.zip

CAM (CM default) -> kowalski-kernel-010p1-std-module.zip (this one will suck your battery dry, it's the default CM mode)

These modules are supposed to work on 10, 10.1 and ICS. Have fun ;)
[LG Optimus 2x] KingMGT:
Hi pengus77,

Can you share for me source code of this kernel?

I want build a kernel for SU660 from source code of this kernel.

I used GB bootloader - CM10.1 temasek. I love your kernel because it's fixed wifi drain.

I forward to receiving a response from you. :)

Thank you so much.

Haha, that's a nasty one. Hope it doesn't recur, could be due to the charger though.
[LG Optimus 2x] pengus77:
Yeah hope so too, really haven't ever seen something like that before :D
[LG Optimus 2x] tavoc:
Hi there,

for all of you which have network losses: what says the radio_log? Something like this?

D/RILJ ( 693): [0206]> REQUEST_GET_PREFERRED_NETWORK_TYPE
D/RILC ( 96): [0206]> GET_PREFERRED_NETWORK_TYPE
D/RILC ( 96): [0206]< GET_PREFERRED_NETWORK_TYPE fails by E_RAIDO_NOT_AVAILABLE
D/RILJ ( 693): [0206]< REQUEST_GET_PREFERRED_NETWORK_TYPE error: com.android.internal.telephony.CommandException: RADIO_NOT_AVAILABLE

I have read here somewhere that it could be related to IMEI/CAL something.

My phone shows me the correct IMEI, but not IMEI SV. My phone number is "unknown" as well (settings --> about phone ...). There was a time I lost my IMEI and I tried to recover it, maybe this recovery process wasnt enough?

Could this be a problem, related to the loss of signal for some of us?

Do your phone knows its phone number under settings?
[LG Optimus 2x] matrixstr:
IMEI and Phone number i have correct, but IMEI SV i have 04, so i don't know it's correct
[LG Optimus 2x] dr.lube:
I've lost my imei sv too after deleting cal.. Dunno how to restore it.. And the number is related with the sim. Long time ago I managed to change it but I don't remember how :(
[LG Optimus 2x] ergoen:
My phone number (in the settings) has always been "Unknown", even on official roms, I think that is somehow SIM or carrier dependent. IMEI SV is also unknown now (don't remember how it was on official). I do not have any call bugs at all though.
[LG Optimus 2x] x_justin:
Imei sv unknown is okay! Thats for ages the case for me, only imei unknown will cause problems. However we need more logs for this. I start to think that its caused by data corruption again. Possible? For me it was gone since a rebuild using the all in one tool.

[LG Optimus 2x] tavoc:
Data corruption could be possible. I have this network losses with newer KK, and I have noticed 4 days ago that my sd-card is dying.

My phone unmounts the card from time to time and the access is slow. In the next days I will try to use a different one and to search for errors on the old one.
[LG Optimus 2x] Ferrum Master:
Phone number is unknown because your SIM card is either swapped and/or cloned and not originally manufactured thus the field is missing.

Unknown IMEI

baseband not properly initialized/RIL/ROM conflicts etc

cal erased

Solution with IMEI rewrite using hyper terminal and stock OS. Google around on modaco section.

PS.

There are possibility when you can call with barked IMEI, because the cell tower sees some sort of default 12345... or zeroes 000000... really, if your county haven't blacklisted them you're lucky.
[LG Optimus 2x] dr.lube:
i wrote a little guide for you to restore the SIM number, hope you will like it :) (it works on cm10 of pengus, tonyp cm10.1 hasn't this feature)

[LG Optimus 2x] ergoen:
Hi, I'm not sure if you were responding directly to me or in general, but for my case the phone number has never been visbile (my SIM is original! I've actually even changed carrier once and none of them showed any phone number). The IMEI is visible and correct, it's the IMEI SV that is not, so calls work as expected (I don't think anything is needed except for a valid IMEI for that?)
[LG Optimus 2x] chp2:
You're right Tonyp, It's not related to the ROM. I had these "lost signal" problems on all the ROMs I had to test for my 2 P990 :

- Pengus CM10

- Tonyp CM10.1 (T04, T05 GCC4.8 & GCC 4.7)

- Civz ICS

Now I'm on kk122 (ICS & CM10.1) and everything is ok since several days
[LG Optimus 2x] frc147:
Hi Pengus,

today i've got my (probably) first network problem: in 2G mode i've switched on data and tried to open xda app whitch told me "newtork error" so i tried to open browser to understand if is a connection or app related but not even this started. I attach the logs and i hope those will be helpfull (because it's my first time XD).

ps. the phone shows full signal and the correct switch to data

My configuration: new Bootloader, Paranoid build 13, kk124, single core mode off, auto hotplug off, mid load balance
[LG Optimus 2x] Ferrum Master:
SIM cards could also be blank, without the correct field, lazy filled. Phone should read my number from SIM cards and thats it. I have 4 cards around now and only two of them show my correct number on any Android device around me. So I guess you are just no good at lottery.

I remember there were tools to read SIM card via USB reader and edit the field by yourself. But who would bother about it a all.

IMEI is visible, ok, but if it is damaged, corruption etc it even could contain a letter in it... hex data fields are simply void.

So some phones revert IMEI if being corrupted to default ones. And usually those are blacklisted by carrier. And people, STOP erasing your CAL data on this phone!
[LG Optimus 2x] tonyp:
You usually can store your telephone number to your sim with an old phone, I once did it with my old Nokia.

afaik the number is just a special sim contacts field - and if it's there or not doesn't matter at all.

And no, I have no idea (nor care) why editing the number seems to work in cm10 and not on cm10.1.

Why would you recommend not to use the erase call data option? It's fixed multiple issues for several people now (see the respective threads, e.g. linked in my good old baseband thread).

As long as you restore your original imei again I don't see why people who suffer from the common problems (wifi data transition) shouldn't try it.
[LG Optimus 2x] Peppe91:
I never changed, touched, played with imei and yes, i do suffer the wifi-data problem..
[LG Optimus 2x] cabral.bh:
Very stable

For me the 124kk is quite stable, with no apparent problems after 65 hours.

Here some screen shots and a syslog complete for analysis.

A modification was necessary to change the cpu governor to conservative because in normal use (screen on) battery consumption was very high in my case.

I now have a battery drain acceptable coming Some cases have up to 3% / h in normal use without "grenify" no application.

Even in conservative, performance is good and fluid. I believe that with the the new ROM compiled in> 4.7 should improve this. I'm just waiting for the bluetooth stack back to bluez ....

Signal Issues

I'm with Pengus on this one, i dont believe the Kernel is the source of the signal drop outs or other network problems.

but in saying that i can only reply on my own experiences ^.^

currently on 26th hour from last boot (rom and kernel flash) - tb5 4.7 clean flash with kk125

so far no dropouts, and all radio services working fine. (GPS, Wifi, Wifi AP, 2g, 3g, mobile data)

I'm using my recommended Baseband found from the LG version link on Tonyp's baseband page.

I've also done the Calibration erase process, also linked on Tonyp's baseband page.
[LG Optimus 2x] Kenks:
it is cpu adjuster ''link''
[LG Optimus 2x] dr.lube:
i really don't think that drops are kernel related

guys with network drops, pls follow the guide of [MENTION=3782272]x_justin[/MENTION] for eresing CAL data and restore IMEI -> http://xdaforums.com/showthread.php?t=2087215

it resolved all my problems related to the modem, i said ALL! :D

(just pay attention that after installing stefan's rom you will be go on oldbootloader)

give it a try :good:
[LG Optimus 2x] jan1000:
Without logcat: it seems the problem of signal drops occurs when the phone is switching between 3g and 2g.

I'm on 124 now, but will try 122.

it's not a drop.. it still declares connection saying E o H but remains grey forever with upload arrow going on and on without any response
[LG Optimus 2x] vs0587:
That is rom related, I always said it in cm10 of pengus thread.. Here too! But I always fish slapped and snobbed by pengus............... I have this problem with every built of pengus rom, but not with Tony p rom, this always with same kernel/version....
[LG Optimus 2x] mas2112:
I've had connection problems since cm7 and still have this problem with all cm builds. Oddly enough, this was never a problem on stock. Never tried stock ics though.

The issue is, my office has no signal. And when I come out of the office, sometimes the connection doesn't get restored until reboot. But I recently found out that switching airplane mode and data on and off somehow restores the connection.
[LG Optimus 2x] LarsPT:
Hi!

Where are you from? I had that problem with stock BB (715?) but after I changed to the BB in my sig I never had that problem again. I was in Paris when I had this problem, I would lose reception in the company's underground carpark and I had to reboot to get reception back.
[LG Optimus 2x] saaavikk:
?!

C'mon people, this is not about whether this problem with signal dropping exist or not?! Yes, there are people that do not have the problem (still, when using 90% of time wifi mode and sometimes 3G, there is very very low chance u can spot it, with 124 kernel), there are people that would have problems with every one of the kernels, because of messed up RIL/BB combination, data corruption, things like that. The majority of people are not having problems with older releases like 122/121 . The 123 release started all this "data connection lost" rumble because of second core hotplug.

People with no problems at all with 124 release, could test the kernel with the option second core hotplug ACTIVATED in kow. manager :fingers-crossed:

I still have problems with 124 kernel with this option activated. Without it, I had only one connection lost problem in 9 days. Let's just see what brings up the next release.

One thing to all: do not post every time U have a problem, even with log attached; :good: FIRST TRY SOLVING IT YOURSELF! :good:
[LG Optimus 2x] imayoda81:
it's been almost two days i've activated hotplug and since then no data problems... i don't know really what's the matter?

but hey , it works with no hassle, resolved problem, so long so good hah

:)
[LG Optimus 2x] x_justin:
Well it would be a great discovery, but then we have to play with hotplugging and try to log it. I hardly can imagine that it has to do with hotplugging, especially that it's solved when hotplugging is ENABLED. Very weird! But we don't have to trigger early conclusions.

For me the problem is solved anyway, don't know how I did it. The only only only thing I can think off that it has to do with sim toolkit. I have it frozen now. Besides that I did a reïnstall of the new bootloader and a new format of all partitions using AIO toolikt. But afterwards, I restored my system and data with TWRP.
[LG Optimus 2x] pengus77:
Uhm so you're saying that with the hotplug active there is no data problem? This is really weird, most of the data control code relies on both cores active...
[LG Optimus 2x] Peppe91:
I would not say stupid things (so if i'm wrong, sorry me) a hypothetical data corruption can affect the problem of the network drop that we have? if we just do a FULL wipe and re-flash bootloader,rom and kernel is there any possibilities to solve the network drop?

I'm just saying this because in my brother 2x with full wipe and kk124 (is the first time that I installed to him a custom rom and I started directly from 124 skipping the 123kk) unless the occasionally drop of performance, he doesn't have any issue regarding the network..( he doesn't live with me so i can't provide any logs or other things unfortunately and he doens't know how to provide one). He doesn't have wifi at home and uses the network connection all the day without any problems.

P.S If I said a nonsense, ignore my post and go ahead
[LG Optimus 2x] tomsi91:
Data and signal loosing and reboots, all finished with v124. Before v124 i tought ill go back to cm7. Since the day of 124 release i have no problems. i had yet more than 150 hours uptime without problem.

[LG Optimus 2x] brugobo:
I never had any data or network problems prioor to kk123. I have started with said problems ever since I installed kk123 about 4 weeks ago (memory is cloudy).

I have had one data problem wih kk123 and one network problem with kk124 (just yesterday). In both cases my phone had an uptime of over 100 hours, the only two occasions where I have NOT rebooted my phone after 1-2 days. Correlation does not mean causatio, I just throw the data point out there.

I do no overclock and use default kowalski manager settings except I enable PSP wifi mode. I usualy run on 2g and switch to 3G when I need to browse on the go.

My IMEI shows properly and I have never erased CAL settings, nor I have the willingness to do so either.

I was using tonyp's PA 11 with kk123 when I had no 2g/3g data (wifi was ok).

I am using tonyp's cm 10.1 experimental build gcc4.8 with kk124 now, and have been with no network for over 24 hours now and it is not coming back so I will reboot. I have noticed it way too late so the ring buffers are likely overwriten. I will provide logs next time if I catch it sooner.
