Hey Pengus77. Im on your latest kernel and on TonyP´s cm 10.1. great rom and great kernel! But I have a question. You said that you have wlan always on, also when screen is off. If I have wlan always on, my phone drains much more battery than without wlan and 3G on. With wlan always on it drains more than 2%/h. if wlan is off, it drains about 0,4-0,6%/H (only lying on the table). Im surprised about that. I ever thought that 3G drains more battery than wlan. Don’t misinterpret this, it´s no problem for me, but im interested how this can be. I have seen screenshots from other users here from the android settings ->battery and they show not really much battery drain with wlan. My phone shows always 100%. Today it shows 5%, but I have set wlan turns off when screen is off.

My settings in KM: PSP ON; Hotspot Management OFF; screen on power management ON; tx power 11dbm.

Greets from Germany and have a nice weekend :)
[LG Optimus 2x] x_justin:
I can confirn your findings. Well let's say this:

- LG screwed up our 3g connection and Pengus was able to fix it back to normal levels. For me it's also about 0,6% an hour draining.

- WiFi is also very efficient in idle mode with PSP on, BUT, only if your router supports PSP well (mine doesn't apparantly, even PSP is a part of the N standard). When I turn on PSP, it drains even more than without it and my connection feels slow. WiFi is also a bit drainy when you are out of range and WiFi is still set at always enabled, it keeps scanning.

So I can confirm that screen off wifi off is a very good setting! WiFi should only be more efficient when in use, otherwise an idle 3g connection should be the best. In our case, Pengus made it both very very nice. However, with PSP I am getting about 0,6% per hour too, but without PSP I am getting about 2%.
[LG Optimus 2x] calav3ra_de:
Strange. Since yesterday night when i plug my phone in the PC, i get a bluescreen on the PC. It doesnt matter if i use the dockingstation or just the usb cable.

At least i could charge it normally via the normal wall - charger and that it didnt crash my house's electric circuit :cyclops:

But i changed nothing on the pc. What is going on there? (Tonyp testbuild 5, kk exp124)
[LG Optimus 2x] mas2112:
This is a driver issue on your PC. I had this problem too with Windows 8. I think part of the problem is with USB3 ports. Can you try with a USB2 port? Also, try installing tonyp's modded driver.
[LG Optimus 2x] calav3ra_de:
How would i install that driver? I uninstalled the LG driver already and now when the phone is plugged in it charges but doesn't crash the PC. but the pc isn't recognizing the phone, and i think going back to the LG driver i wont be able to update the driver of the device in windows because it will crash when plugged in. The modded-driver thread also doesn't explain this.
[LG Optimus 2x] DrummerMuppet:
Installation instructions are clearly stated on the first page of the thread.
[LG Optimus 2x] Patrick Morgan:
Also i have had no problem using the drivers provided in the AIO tool.

Granted that may just be my pc, and its own USB drivers, but just to say there may be different setup configs for different folk.
[LG Optimus 2x] calav3ra_de:
Since i told that the pc isnt recognizing the phone, you might have concluded that i have no item similar to LG-P990 or anything close to that in the devicemanager. And thus, i wasn't able to install the driver at all (and kept asking for how doing it).

Anyways, it works with the LG driver again. Maybe it was the circumstance that the phone battery was completely discharged? Maybe i can tell next time it is empty.
[LG Optimus 2x] DrummerMuppet:
Did you try installing the drivers using Spyros' AIO Tool, as [MENTION=894978]necrowakker[/MENTION] suggested?
[LG Optimus 2x] Patrick Morgan:
As the phone drivers are not installed at this stage, it shows up in the USB section of the device manager, with a yellow mark on it.

if you choose to update driver, and navigate to the folder where you downloaded Tonyp's drivers and install you can do it this way.

or you can use the AIO tool, to install the drivers correctly for your phone.

Also, i would recommend looking into updated drivers for you USB card / ports. as some default Windows drivers just are not good enough for complex things.

Thanks Drummer, Yep, the AIO tool has been a very handy application of different tools to help sort out alot of trouble shooting.
[LG Optimus 2x] calav3ra_de:
I have of course closely watched the devicemanager. Nothing was installed, and nothing new appeared (i also enabled hidden entries), No entry i could identify again associated to the phone. Nada, seriously.

As said, LG driver works right now. I will see what happens in the future, and report back. Right now adb/eclipse,ums work just fine again.

I didnt try the AIO tool since it works again. Thanks for the help guys :)

Quick Poll

Guys,

the stuff i'm working on right now is: 1) dynamic ramhack and 2) new battery driver. Both of those features will be ready in a few and will need a load of testing before i can safely push them out. This means that i'm planning to hold them back for a few and will focus only on making 125 the next stable release. I think the actual state of 124 is pretty solid, aside the dynfsync problem that is already fixed in 125pre. Please let me know if 124 (consider it as if dynfsync was stable) is stable release material or not and i'll push out 125 tomorrow for the last rounds of tests before re-releasing it as M1. If you don't think the kernel is ready to be considered stable then please shout here the bugs (serious ones) you have and we'll discuss a bit.

Thanks :)
[LG Optimus 2x] Patrick Morgan:
Personally, i've found no problems with 124, .. the issues i've had with my phone was related to either rom, app, or baseband in the last couple of weeks i've been using 124.

so except for the fact i was not using dynfsync, =P everything in 124 worked great for me. - also if you want me to play around with your pre builds i got time for now to do some testing. ^.^
[LG Optimus 2x] andreilica:
On 124 I got my first BSOD. I put my phone to Charger and found it dead. No logs, had to remove battery. Few pages back I made a post regarding hard resets on 124. There are some logs too. On earlier releases, neither of those were present. Hope I helped you somehow.
[LG Optimus 2x] Bastlwastl2010:
124 Is stabie here since release in Tony Bild 04

[LG Optimus 2x] 60nine:
similar thing happened to me today... phone on charger overnight, woke up, phone dead...
[LG Optimus 2x] pengus77:
Unfortunately the logs i received showed no problems at all with the kernel. We also recently discovered that rom bugs can cause bsods/reboots even if the kernel is perfectly stable. What rom are you two using ?
[LG Optimus 2x] poruid:
I experience the same problem with kk124, tonyp cm10.1, newbl, bb 30a on p990 A03, when connecting adapter while phone is sleeping. Oddly, if ignored, the phone seems not to load.

Hope this info is useful, good luck.
[LG Optimus 2x] chp2:
Pengus,

For me, the 124 is not bad at all but suffer huge performance drops and the phone warm alot when on heavy load (large HD videos, games, GPS apps,...). Yeah I use a lot my phone...

So, I reverted back to 121 (best one in my case) for every day use where I don't experience the same problems.

In both cases, I tested with latest Tonyp's CM10.1 and your latest CM10 after just a kernel upgrade on an running ROM or after an install from scratch.

I hope the 125 will correct these 2 problems above.
[LG Optimus 2x] 60nine:

[LG Optimus 2x] rzlatic:

[LG Optimus 2x] SamReciter:
Hey there, no crashes of any kind with 124 here. Standard use: email, SMS, g+, xda, spotify, photo, etc. - little dev use wifiadb and file explorer and... Ah yes - some phone calls ^^.

Greets...
[LG Optimus 2x] winstonxl2:
i dont know or it works but try stay awake it may work i dont know i also came much times almost too late on school so this problem need to be find out on every rom or it is good compatible.hope i wil wake up tomorrow

i hope that stay awake prevent deep sleep for some people.

if you want to acces dev options in 4.2.2 tap 7times build number and then press 4times more.

[LG Optimus 2x] Peppe91:
Sometimes I still lost my network data without any reason, it happens like 3 times a day.. I've to reboot the phone to get it working again..
[LG Optimus 2x] dimedevil:
same here.... that's why I reverted to 122 which is stable for me... I also got the "bsod when charging" bug when using 124
[LG Optimus 2x] saaavikk:
Stable kernel

I consider 122 stable release. In combination with 019 Kowalski manager, U can change the auto brightness (too bad it can't be set lower than 5) and the auto brightness sensor reacts faster.

The kernel seems to be more powerful in terms of gaming...and I doubt that the missing dynfsync in 124 could have such an inpact. :confused:

The 124 is stable in terms of signal loss (when 2nd core hotplug is off naturally) but for me it's just less stable: had 1-2 bsod with it, with 122 not single one problem.

And once once more, in clock to clock comparison the 122 is faster than the 124 release, not only smoother!

Always tested with same combination of ROM/Kernel - Look Ma/122/124; TonyP04 CM10.1/122/124

So 124 is not bad, but I would consider 122/121 as stable branches.:good:

---------- Post added at 07:43 AM ---------- Previous post was at 07:38 AM ----------

No need to reboot, just turn off data, start searching for networks, after 5 sec U can cancel the search, turn data back on....
[LG Optimus 2x] Patrick Morgan:
I've a strange feeling the BSOD most folk are experiencing (if they are charging from USB on their computer) could be related to the old drivers,

i updated my drivers for my laptop, (i also reinstalled my laptop a short time before that- and found newer drivers for my computer, usb included)

I'm just wondering if some of the issues we're facing could be external to the things we're using, I.E newer software on our phones requiring new drivers to run on our computers.

I've been trying to mess around with my phone alot to make it brain fart, but all im getting is solid stability. if i do find a problem, I try to figure if its something i've done, rather than something in the rom / kernel.

if those experiencing the BSOD, charging from windows, please take a gander around for your manufacturer drivers, and see if there is newer one, .. not just the windows drivers, (they su*k) and see if it possibly makes a difference. i do remember getting BSOD problems back during the release of ICS, i related it to a windows problem before looking at my phone, and its gone now, I've not had it for months.

Anyway, just my two cents on a possible solution.

Regards
[LG Optimus 2x] BS86:
I had that problem too, 2 times. On my device, this did not help (Searching gave "network error" when clicking it). Also, Airplane-mode would not start, the Network-icon disappeared, but no airplane-icon appeared, even after 5 minutes, and after disabling the airplane-mode, everything was like before. Only restarting the phone solved the problem.

Unfortunately, I could not make logs, so did not happen

Edit: Just read the only data lost ... on my phone, even connection to normal phone network was lost (no calls possible, no sending of short messages), although the bars were full, but grey.

T-build 04, KK 124 - did not have problems with 122 and 123
[LG Optimus 2x] Patrick Morgan:
It may be Baseband related, .. or if you've done alot of baseband flashing, give a look into the Cal / IMEI restore process. its meant to fix alot of radio problems.
[LG Optimus 2x] BS86:
got the phone brandnew in june 2012 with a V20* - firmware, updated it to V30A in november 2012, never touched BB again ;) And never had problems with radio since the beginning, so i don't think it is related to that.

will see if 125 fixes the problem, if not, i might give another BB a try.
[LG Optimus 2x] pengus77:
Let me understand this guys... 122 is perfect for you all, while 123 and 124 give problems with network ? This makes no real sense, the main changes have been applied in 122 with the introduction of topology and mutex/timers changes. Please let's try to understand perfectly what could have caused these changes, also because the problems seem to appear on all roms, not only on a specific one.
[LG Optimus 2x] Peppe91:
I lost the network signal and data with kk 122,123,124.. Only with kk121 it seems to be all fine.
[LG Optimus 2x] Patrick Morgan:
Its the auto brightness ramp mod, its making everything come out like rainbows! :p
[LG Optimus 2x] pengus77:
I also need to know if the network losses appear when using cpu hotplug, single core mode or even with both cores active.
[LG Optimus 2x] rafabad:
I never had network problem with 123 and 124 kernel. My rom is 10.1 build 4, BB is 30B and no changed ril. I use no load balance.

Perhaps these problems discussed are related to this:

[LG Optimus 2x] x_justin:
Its not unfortunately. For me the problem is known, I used to have it on look ma and tbuild 5 but since I try to log it the bug is gone! For me it happened with max load balance and 2nd core always on. It happened three or four times but after a nand restore to nightly 122 and a flash of 124 the bug is really gone. For me its a solid kernel for days now.

Verstuurd van mijn LG-P990 met Tapatalk

Maybe, maybe, maybe, this is a log. I don't know if it's sufficient and if the problem is captured here. I exported one to my dropbox on 12th of june. I had a signal loss and my phone hang and got a soft reboot. I don't remember my setup from that day but the last kmesg was filled.

I can see something like:

The log is here
[LG Optimus 2x] Peppe91:
I lost the network with both cores

. I never Enable one core or hotplug..
[LG Optimus 2x] saaavikk:
For both roms following config: NO cpu hotplug, I remember huge problems with 123 release where this was nature behavior of the kernel, in fact it makes thing worse (battery life better) in matter of occasional network data lost when activated in KM 020 and 124 release. Never used single core mode, always both cores active, no special profiles for screen off in cpu adjustment utility. In fact the connection lost happened to me during browsing, while being stationary (so both cores active and hand-off to other BS is off the table). :(

Dynamic fsync always active.

Activated Max Load balancing for all kernel, doesn't seem to have any effect.

But like I said, with 124 release, the connection drop is super rare for me (with NO second core hotplug) . And when it occurs, it's easy to get it back with the procedure described. I moved to 122 because of brightness sensor behavior and performance issues with 124

One last thing, with v30A baseband I had complete drops, not able to find any mobile providers (scan error). Moving to v30B baseband helped to get rid of this kind of problem and it solved for me the data lost on 122 kernel completely.
[LG Optimus 2x] BS86:
those problems occured only with 124, auto hot plug off, single core off, can't really remember if it happened with autobrightness on or off, but i think it happened with both, but "only 2G" mode was on.

I use 3G and 2G now since 2 days and did not have the problem again - will try tomorrow if it comes back in only 2G mode.

edit: max load balance settings everytime
[LG Optimus 2x] Luk_Optimus:
For me 124 is stable besides dynfsync..

The network problems are gone since 124 (had 122 before).

My settings:

-max load balance

-single core off

-auto hotplug (don't know, but not changed)

using 2g only and 3g...

Edit: Rom: tonyp build 4
[LG Optimus 2x] rzlatic:

[LG Optimus 2x] Luk_Optimus:
In the very old days, before pm and other optimisations i never had a problem.

Than there where some really bad ones.

Now it is Good, happens very, very rarely, but not reproducable..

Maybe we should start a poll about baseband and networkconnection..
[LG Optimus 2x] DrummerMuppet:
+1 here. Even sometimes the signal shows as stable, blue bars and everything, but no data connection at all (haven't checked if this also affects calls, though). Usually a reboot is needed to gain data signal again.
[LG Optimus 2x] pengus77:
The weird thing is that i'm experiencing randomly the same problem also on my gnex with aospa and franco.kernel... need to go check what common commits we have...

In my case it affects even calls.
[LG Optimus 2x] andreilica:
Yes, I'm having this issue with losing signal too. Sometimes it gets stuck at 1 line or 2 lines and I can't do anything. And sometimes I cannot turn off the mobile data. It remains on whatever I do. A reboot is needed in that case.

Today something strange happened to me .. Parts of the screen started to go dark. When I turned off the screen and put it back on, they were gone for like 5 seconds, then they would appear again. Like my screen was dying . :)) After a reboot it was solved.

Just out of curiosity, can anyone try with an older rom version ? Tonyp's build 1 or an older PA or my feb cm10 build ? Or even with ICS... i'm not 100% sure it's kernel related at this point and i'm starting to think it could be some common commit in the last builds we (Tonyp and I) made.
[LG Optimus 2x] Kyrandialegend:
In my experience I have no losses on LookMaNoHands with kk122, but i have losses and no network with kk123 kk124

Edit : no network issue happens after beeing for long time in low/none signal area
[LG Optimus 2x] Custom40:
Does this count: network lost and download of a 200mb file failed at 91%? :P

But seriously, think about it. It is really really really really really really rare these network loses happen. Personally, I can't even remember when I had one prior to the one time I had earlier today.

I'm on PA13, kk125, if you think it's worth the time, I'd be willing to have an old PA build for a few days even though these network loses are way overrated and exaggerated. Which PA build would be reasonable to revert to, you'd think Pengy? :)
[LG Optimus 2x] zchuxz3x:
Pengus, I have noticed that the data signal loss occurs especially when (possibly) the phone "Log-In" in another cell of the network provider. I say this because I've noticed it happens mostly when the data network is being used while I'm on the move (car, bus, etc. ..). will be related to "Fast Dominance"? ..

I doubt it's the ROM, for three reasons:

official CM10 (so the codebase for your cm10 and my PA) is pretty much deprecated.

I just generated a full changelog (git log) for PA13 and and couldn't find anything from the core packages which could be related.

One exception: Your RIL fixes for call muting and call forwarding - but I can't see how they're related.

I didn't hear about the radio drops immediately after releasing PA13 - they started a little bit later with the new kernel releases

Last but not least: Most people report that the problems are gone after downgrading the kernel!

The darkening screen caused by the too high brigthness. Set the birgthness to 1/2 or 2/3 on the scale then the problem will be gone.
