well in that case, that sounds like a radio/tower issue...
[Samsung Galaxy Nexus] Khizar:
The data drop issue isnt kernel releated, its a 4.2.2 bug, its been confirmed in the AK thread.. Stefano had the bug on an S2 running a 4.2.2 rom and CR88 has the bug on the N4 with any rom/kernel combo...

PS- and another thing AFAIK kernel affects wifi but has nothing to with gsm network/data

Edit- i stand corrected, AK was talking about wifi drops and not data drops :o

Sent From My Galaxy Nexus With AK Awesomeness To All You Wonder Nobodies!!
[Samsung Galaxy Nexus] parkson:
The data drops we are discussing started after the r25 release, and mainly affected Toro users. It seems maguro users didn't get the drops until one of the test releases of r26.

I've never suffered drops on this phone before, and they didn't happen until r25. If you go back in the thread you'll see the catlogs I posted for every subsequent release since r25 (including every test). I seemed to be suffering drops the worst, or was the only one who knew how to post logs.

Tst-r27-01 seems to have fixed the drops for me. It's unfortunate maguro users are seeing "drops", although I'm not quite convinced they are the same "drops" that toro users encountered.

If you understand how to read logs, or know anyone that might be able to share insight, please do go back in the thread and take a look at the logs I provided in the past.

[edit] and to be clear, none of this has to do with WiFi. During all testing I left WiFi OFF because problem was with data/cell signal.
[Samsung Galaxy Nexus] Blackcrx:
I think you're getting data and WiFi drops mixed up. AK confirmed WiFi drops, I've always had WiFi drops with AK but very rarely with Fancy.

My maguro never had a single data / network drop once.
[Samsung Galaxy Nexus] ak:
I have confirmed that wifi drops arent kernel related ...

[Samsung Galaxy Nexus] shawnaye:
Ok enough with the questions guys. We gotta get back to fixing it.

Let's end all the confusion here.

If you don't got a data drop, just enjoy the awesome kernel.

If you do got one, grab a log.

And no, wifi bars becoming gray isn't a data (3G signal) drop.
[Samsung Galaxy Nexus] Blackcrx:
Yes I know. WiFi drops have been a 4.2.2 issue. I believe Khizar is getting WiFi and data drops mixed up. If you read Khizar post, he said you confirmed data drops arent kernel relit ed which isn't true because you said WiFi drops arent kernel related.

Fancy data drop started happening after r25 but totally makes it a kernel issue since it wasn't present on r24

---------- Post added at 09:33 AM ---------- Previous post was at 09:31 AM ----------

Agreed. But we need to explain to ppl what a data drop and what a wifi drop is. Last thing we want is ppl reporting incorrect problems or issues.

Maguro here with no data drops at all.
[Samsung Galaxy Nexus] boype:
Bottom line is:

There is wifi drops and there is data drops. They are two seperate things. I'm focusing on fixing the data drops that were introduced with r25 of this kernel. The kernel IS responsible for these drops, we have tested this.

A data drop is when the mobile network data connection (4g, 3g, ...) is lost and cannot be re-established without a reboot.

A wifi drop is the wifi disconnecting itself during idle. It is reflected by the wifi symbol in the status bar is either completely gone or just grey when the phone is woken up from sleep. The wifi connection re-establishes itself within seconds after the screen goes on. With the wifi drops, messages and emails are still received (but may be delayed some minutes more). This is in fact an Android 4.2.x issue happening on several different phones and is probably unrelated to the kernel.

Hope this clarifies things.

That said, it looks like r27 test 01 fixes the drops. I'm 99% sure the issue was caused by changing the 729 MHz CPU step to 806 MHz. Don't ask me how this is possible, I would never have expected this to be the cause. I have identified this (with your help) by trial and error. Anyway, it's good the cause seems to be identified. I'll wait for your feedback for another day or so.

All honor.I really appreciate,that you were able to confess,that the problem is into kernel.In some kernel thread(s),you can often see statements like "not kernel related" even when problem is definitely kernel related.

You consider,that problem is kernel related and you found solution very fast.For me,this is a sign of real and great developer.Thanks for your work.

I already asked renaud about this and he pointed me to the following commit:

https://github.com/renaudallard/gnexus_kernel/commit/9425bf37d2108b96e44a3c8684e8f12a958b4373

Now, for clarifcation, I am talking about WiFI patches released by Google apparently and not data drops.

So, boype, can you look into this and see if this can be integrated into fancy and whether or not this helps with the known 4.2.x WiFi drops.
[Samsung Galaxy Nexus] boype:
Thanks for notifying me. I have already pulled patches from the Google repo before, this is where renaud got the patch from. But I was not aware of the latest change (10 days ago) you are reffering to. I will include this.
[Samsung Galaxy Nexus] sajty:
New test version? :laugh:
[Samsung Galaxy Nexus] boype:
I'll put up r27 test 02 in a bit. This is more like a release candidate (RC) version than a test :)

[edit]

r27 test 02 is up. For the data drop people (toro users): This should still have the issue fixed, but please report back to be 100% sure. Thank you for testing and reporting and remaining patient!!

If you had r27 test 01 installed, I highly recommend you do the following to revert a change I did for testing purposes:

- in a file browser, go to /system/lib/modules

- delete all .ko files (NOT THE .ko.bak FILES!!!)

- rename all .ko.bak files to .ko

- done.
[Samsung Galaxy Nexus] Lancez:
Do we need to delete all files in module folder before flashing r27 test2?
[Samsung Galaxy Nexus] boype:
Not necessarily before the flash. You can also do it afterwards
[Samsung Galaxy Nexus] OU']['lander:
Sorry Boype, in this release 27 test 02 are there Wi-Fi patches which were mentioned some posts above?

Thanks in advance ;)

[Samsung Galaxy Nexus] boype:
r28 available

Hi all,

r28 is uploaded. It fixes the infamous toro data drops that were introduced by r25 (I'm 99%sure it does). But it also has more to offer :)

Change log:

fixed toro data drops (revert back to 729 MHz CPU step)

bcmdhd (wifi): pulled an update from the Google repo ('Fix sched scan processing')

mount /cache partition as data=writeback (no journaling; faster)

renice systemui process priority with -17 instead of -20 (-20 was too much - the phone used the maximum CPU frequency too often. I have tested this extensively.)

build wifi driver as a module (it appears there's less RAM usage with this method; to be confirmed)

disable swappiness on boot if zRAM has not been enabled (there's no swap device then, so why keep swappiness!?)

one small scheduler tweak

Enjoy the release, from my perspective, I would like declare it very smooth, stable and bug-free - but that remains to be seen :p

Best regards

Apps crashing on open for me after flashing latest Kernel. Looks like wiping said apps data resolves the problem after a reboot.... At least it did for Chrome. Other apps still won't open. Going to wipe cache now from recovery. Will report back.
[Samsung Galaxy Nexus] kinfolk248:
interesting....report back on that
[Samsung Galaxy Nexus] dmillerzx:
Reflashed kernel, wipped cache, now all apps will not open. Including Chrome which I had fixed prior to reflashing by clearing app data. I came from the latest experimental, and AK prior to this. There has to be something obvious going on here.

---------- Post added at 01:10 PM ---------- Previous post was at 01:08 PM ----------

I can't start SSHDroid or a File Manger in hopes of removing the .bak files Boype had mentioned earlier. I did not remove those files if they are there. Looks like I might have to start from scratch. :/

Update: So it's note all of my apps but quiet a lot of them.

Also wifi cannot turn on. Greyed out. Something might be wrong with the latest version. I'd say people should use the latest experimental until Boype has a look. I was not having any of these issues while using the latest experimental...
[Samsung Galaxy Nexus] differentstyles:
Same Problem here. Can't activate wifi. Flashed Kernel and rom again. No chance. Switched back to r27 for now. But it was super smooth :).

Edit: just saw your answer to that. :)
[Samsung Galaxy Nexus] boype:
Fixed, links back up.
[Samsung Galaxy Nexus] dmillerzx:
Looks like my issue with Apps crashing as soon as they open was related to the latest version of the kernel. Dirty flashed r23 and all problems went away.
[Samsung Galaxy Nexus] boype:
It has to be related to the changed /cache mounting. I recommend you wipe cache... Should fix it IMO.

I already had the mount in the latest test versions... Strange that no one reported anything
[Samsung Galaxy Nexus] dmillerzx:
Reflashing r28, then wiping cache did not fix the problem. Dirty flashing r23 over top without wiping cache did. lol strange. Going to try flashing the fixed r28-ext. Thanks for your quick support Boype

---------- Post added at 01:26 PM ---------- Previous post was at 01:22 PM ----------

Now that I think about it.... I actually first noticed the issue when Chrome failed to open when using Chrome-To-Phone to grab the latest stable r28. I had only been using the latest test version for about an hour prior to moving to r28. So it could have been there the entire time and I just didn't notice it until right before I was flashing r28 where the issue persisted.

Update: OK flashed the fixed r28. Wifi can now toggle. Can't connect up to my normal AP though as it keeps saying Authentication problem when I know that the key is in fact correct. I Flashed r28 then wiped cache and dalvik. I'm still having issues with some apps opening. For instance File Explorer, and Facebook crash - I'm thinking if I wiped their App data they'd work. But now a new Wifi issue. Hmmmm
[Samsung Galaxy Nexus] boype:
Anyone else having Wifi issues or crashing apps???

I'll be at the movies for some hours but will check back in here later on.
[Samsung Galaxy Nexus] jjhrrsn:
No issues at all
[Samsung Galaxy Nexus] dmillerzx:
Boype, dirty flashing Fancy r23 (just the one I have on my phone), or AK 256 resolved both the Wifi issues and app crashing I was seeing. I would like to report that it appeared that the Toro data drops have been fixed :) :)

Interesting. Will try this governor for sure. FWIW, have you looked at Intellidemand? I'm running it on another Maguro with Air Kernel. Looks to me that Intellidemand keeps the 2nd core offline a lot longer than other hotplugging governors, only bringing it online when necessary, yet it is stable and snappy. Anyway, just food for thoughts..
