we have verified on FXP build that CIFS was causing main issue... i went back to 2.6.32 CAF cpufreq driver and modified it as it is less messy :p and it works great at the moment ;)

"display sucking battery at an insane rate" << that u cant do much about, what did u expect from a 3.7''+ display :D

1) nope kernel will not "automatically overclock", it will always boot at stock kernel frequencies for ur device

2) where did u hear that? not true... offline charging works just fine on STOCK rom... if u use any other ROM/mod then i cant guarantee it...

3) this kernel will root ANY FIRMWARE for ARC/ARC S

not any time soon... i am busy with some personal work...

first... STOP USING LARGE BOLD FONTS

kindly mention in detail which ROM & firmware did you use... provide screenshots of about phone, logcats when error occurs...

from where do u think we have the extra 20MB RAM? we have reduced the RAM from camera & from audio driver... from our tests on all Xperia 2011 devices (tests done by jerpelea & verified by me on ARC, PLAY) this "recovered 20MB RAM" didnt cause any issues on those devices... so if u indeed are having issue give us COMPLETE details of your setup...
[Xperia Arc Android Development] rustynuts34:
Hadn't tested mine but also installed arconium 6 update at the same time, can also say that cameras not working "unknown error" I'm assuming it's the Rom. :-/
[Xperia Arc Android Development] DooMLoRD:
i am testing on .62 stock firmware and camera is working fine... taking pictures, 720p HD recording is all fine...

can u verify on ur phone if u have same issues with .62 stock firmware + my newest kernel (v18)
[Xperia Arc Android Development] Flo95:
Not for me, works fine and I'm on arconium 6.0, too.
[Xperia Arc Android Development] dp94:
I've the same issue with v018 & Acronium 6.0.

I also don't think it's kernel related. ;)
[Xperia Arc Android Development] pulz:
Thank you !

Been testing this on Stock FW .42

Then on arconium 6.0

With v17FIX2 everything seems to work fine.

Great Kernel.

Flashing baseband 36 really got me a new lease on battery.

Going to post on a guide on flashing basebands after your private message doom tomorrow.

Thanks for the help and free software !
[Xperia Arc Android Development] AmitPeri:
I have the same problem. I'm on the .58 stock firmware and .58 baseband with version 18 of your kernel.

Video is working fine and also I can take pictures with a camera app from the market but not with the stock camera. its starts to take the photo, even the flashlight and focus stars to work but then it gives me the error.

Besides this bug everything works great, thanks Doom.
[Xperia Arc Android Development] DooMLoRD:
@mehdi.xterra & rustynuts34

seems there is a bug in new kernel...

one user just contacted me and pointed me towards the correct place..

[ bug/issue ]

apparently "image stabilization" sometimes doesnt work in capture picture mode (its in advanced settings)

[ reason for this bug/issue ]

since we have taken some RAM away from camera the additional features/functions of camera are getting affected... we had not run into the above bug before, but now that we have checked and recreated the issue we can fix it :)

[ temporary workaround ]

if u disable "image stabilization" u should be able to take pictures...

i will revert this in my next kernel release... i dont want to break the awesome features of ARC camera ;)
[Xperia Arc Android Development] AmitPeri:
I'v just restored the data of the camera app with Titanium backup and its working again. including the image stabilizer.
[Xperia Arc Android Development] iridaki:
Thanks Doom! :)

Member TCR2 emailed me a few moments ago too and asked me to post this here on his behalf:
[Xperia Arc Android Development] dp94:
Thanks doom for such a fast solution/workaround. ;)
[Xperia Arc Android Development] Flo95:
Make sure to disable image stabilisation for videos, too.

Otherwise portrait didn't work for me and now it's fine.

Also I think pics without image stabilisation are better, just useful for videos.
[Xperia Arc Android Development] DooMLoRD:
well we have reduced the RAM dedicated for camera from 50 MB to 30 MB (thats where the 20 MB RAM came from :p)...

i have talked to jerpelea and according to him increasing the allocated ram further by 2MB to 32MB should resolve this issue...

lets see i am testing that right now...
[Xperia Arc Android Development] Flo95:
Thanks for your fast work.

I hope that fixes it and we can keep the plus of RAM.
[Xperia Arc Android Development] Ninolina:
I have tested v 18 WITH BASEBAND .36 and after a 23 hours:

0.3-0,4% per hour without WiFi, Backgrounddata off, pushmail off, DATA OFF (Screen OFF)

2% per hour with WiFi on, BackgroundData and push mail on (Screen OFF)

It's working OK but it use more battry than v17 version with WiFi on, BackgroundData and push mail on (Screen OFF)

..:-( I don't use default camera app so I cant say about issue you are mentioning.With lgCamera app I don't have issues.

My settings were:

CPU freq min/max: ~250MHz/~1.4GHz (ARCS S)

CPU Governor: Ondemand

hi doom... first of all i want to thank you for your kernels!!

i'v just flashed the v18fix1 and i noticed that the RAM decreased to 345MB instead of 356MB... i thought that just 2MB decrease would fix the camera not 11MB... isn't there a way to keep the RAM and fix the camra???

Install busybox in /system/xbin/ and use an init.d script to give preference to that busybox... export PATH variable with that path appended at beginning...

E.g.:

export PATH=/system/xbin:$PATH

I did a lot of testing yesterday, this seemed to best combination to not break any camera features...

I can reclaim all 50MB dedicated to camera but then camera wont work...
[Xperia Arc Android Development] doomed151:
I still don't quite understand. Even if the camera isn't being used, that 50 MB is still reserved for it?

Camera problem for me too...but i did

1. Put on Normal Capturing Mode rather than Auto. However, in Auto mode if enough available light...the camera will capture.

2. Disable image stabalization...

Video was working fine for me...
[Xperia Arc Android Development] Flo95:
Flash the fix and you can use all functions without a problem ;)
[Xperia Arc Android Development] cruzargel:

[Xperia Arc Android Development] DooMLoRD:
Yups... not just for camera a lot of ram gets reserved by kernel for a variety of things...

Interesting bit is, on Xperia Play the amount of ram reserved is far less... that device has 370MB RAM available...

The Exmor sensor (arc) seems to reserve a lot more ram...
[Xperia Arc Android Development] iridaki:
Yes it is.

[Xperia Arc Android Development] Flo95:
Switched 10 times between photo and video, no problems here.
[Xperia Arc Android Development] John_2k2:
After using this for a day or so battery has been little worse than previous version (v15) I was on I'm on about 51% though before I would be aroung 60-70% . But performance has been better and smooth , using Smart ass V2 and at stock speed. No camera issues nor light either everything works. Great Job.
[Xperia Arc Android Development] memtronic:
Thanks DooMLoRD!

v18 fix1 works o until now. Battery drain is gone. That's for sure. Battery life is at least as good as stock. (Tried more kernels, but that's the best for battery). As for smoothness there's no one like it :D

Some camera crash may occur if switching repeatedly between photo and video, but that's not the case for normal use.

I want to see how it will behave for several days of continuous use with no restart (1-2 weeks). V15 always ended for me with random bootloops, after several days of normal use, at stock speeds; taking into account battery drain too, it wasn't a nice experience, so i reverted to stock, then to Advanced Stock.

Hope this one does not reboot itself randomly :)

Anyway, much appreciated work! Kudos!
[Xperia Arc Android Development] Ninolina:
I have tested v 18 FIX1 WITH BASEBAND .36 and after a 21 hours:

0.3-0,4% per hour without WiFi, Backgrounddata off, pushmail off, DATA OFF (Screen OFF)

0.8% per hour with DATA on, BackgroundData and push mail on (Screen OFF)

2.2% per hour with WiFi on, BackgroundData and push mail on (Screen OFF)

It's working REALLY GOOD but it use more battery than v17 just like v18 (FIX1 even uses more) with WiFi on, BackgroundData and push mail on (Screen OFF)

..:-( With v17 it was using only 0.7% per hour with WiFi on, BackgroundData and push mail on (Screen OFF). Something happened with WiFi usage...:(

[Xperia Arc Android Development] Riyal:
Hi! I don't think WIFI is different from 15 to 18 fix1. The modules are just the same and I can see that doom haven't altered anything on the communication part of the kernel for it to eat more battery than before? I'm sure there must be other causes than doomkernel.

Current changes of the kernel are just

Cleancache - Memory management/RAM memory compression.

zram - Memory management/RAM memory compression.

CPU freq driver - fixes the hidden battery consumption bug which is not detectable by any battery stats applications(including betterbatterystats).

Video/Image rendering memory allocation - Reduced the allocated memory for handling videos & image capturing/recording for the sake of more memory.

Disabling CIFS/NFS - removes support for Network File Systems which is said to eat more battery life.

Only changes Doom made that should affect WIFI is Disabling CIFS/NFS but that was suppose to reduce battery consumption.(Not sure if this was implemented on v15) :confused: :D
[Xperia Arc Android Development] arcanixX:
Doom, is there any script or something to remove/disable the "new voicemail" notification? I really hate it and since the last kernel update, it's not going away even when I call to the VM and delete msgs. I even tried leaving myself some VM and deleting, but nothing :( this used to work before. I can't install google voicemail because it's not available for my country. I don't care about VM's, I just want this notification to go away forever.
[Xperia Arc Android Development] ngochuy:
So the most stable version until now is v17 fix 2? Can anyone confirm? Thanks

Sent from my GT-I897 using Forum Runner
[Xperia Arc Android Development] iridaki:
Are you sure this is kernel related? If you flash stock kernel back, the notification disappears?

iR¡D@k!* via Tapatalk
[Xperia Arc Android Development] DooMLoRD:
Is this happening often and for everyone?

In that case I will give the camera back the 10MB RAM we salvaged from it...

Nothing related to WiFi has been touched yet...

WiFi modules are still from v15 kernel...

Not too sure what to do/say...

U can modify the script to use /system/xbin/busybox

And anyways there is no need to keep upgrading busybox... No real benefit...
[Xperia Arc Android Development] kurnage:
My Camera is working fine after the fix. Thanks :D
[Xperia Arc Android Development] dp94:
I haven't noticed any problems neither. ;)
[Xperia Arc Android Development] harfot:
No it works fine with fix 2, not even fast switching between the two modes creates any errors.
[Xperia Arc Android Development] memtronic:
It is happening randomly(meaning it could not happned too) if you switch fast and repeatedly (more than 4-5 times) from photo to video and back. But there's no bother since this scenario is highly improbable in "real life". :)

Hi DooMLord

I installed v18 xperia arc s, the camera error:confused:, I tried several times but still is not, then I reinstalled v17 fix2, the camera work:eek:, pls check me, or I did what's wrong, pls help me, FW stock 2.3.4 buil 62, sorry my english is not good:(
[Xperia Arc Android Development] realfelix:
Hey doom :) is it possible for you to raise the fps cap to 62 instead of 59/60 ? Thanks :)
[Xperia Arc Android Development] Rycon33:
yes it's happening to me sometimes also, even with the fix version18, when switching from video to camera, will have error"camera not available", then needed to exit from the app. it's seldom but it happens.
[Xperia Arc Android Development] harfot:
Over the last ½ hour I have tried with slow and fast switch 2 time, 5 times and between 10 and 20 times - I cannot reproduce the error. Are you all on stock ROM? Have you wiped the dalvik after installing fix 2 (almost always necessary after change in mere allocation)?
[Xperia Arc Android Development] Rycon33:
stock ROM, doomkernel version 18fix1

of course, whenever changing kernel, i wiped cache and dalvik cache

what we're saying is, it sometimes happens to us, you or others may not encounter it

anyways, not really a big deal for me personally, just needed to exit/reopen the app whenever it happens
[Xperia Arc Android Development] harfot:
Try it with fix 2 - it has a cure for the problem.
[Xperia Arc Android Development] Flo95:
V18 has only one fix...
[Xperia Arc Android Development] Riyal:
Doomkernel's ramdisk contains an old version of busybox which is a symbolic link from a file named recovery. Supercharger script uses $PATH system variable wherein on doom's kernel defines /sbin as the 1st priority folder to look for binary files.

so installing busybox on system/xbin or whatever directory it is will be overriden by the busybox from /sbin/

2 solutions for that is to create an autostart/init.d script to redefine $PATH variable to use /system/xbin first. Or modify the ramdisk directly(if you have linux OS)
[Xperia Arc Android Development] cyberdelia:
I can't make it work.. I don't know if the problem is the Kernel, or the ROM.. or the partition format... or what??

I'm with Rev18 (v04) kernel, 1.6Ghz, installed the CM7 7.1.0.2... when it loads the first time, everything freezes.. the icons doesn0t appear, the status bar doesn't respond.. the phone doesn't even knows that I'm calling from another phone to it...

So, I try to change to another ROM.. a MIUI x16, and it keeps in a loop of restarts.. I tried the kernel 2.0Ghz also, and nothing...!

Anyone knows what I can do?
[Xperia Arc Android Development] isangelous:
This kernel is not for CM7 - it is for stock roms. There is another kernel for CM7 in a different thread.

I was on baseband 56, and kernel v17. I thought I'd keep my phone up to date, so i was installing kernel 18. I then read that you recommended baseband 36. I installed 36, but nothing bootet up, I then tried flashing baseband 64, 56 nothing happened.

Then I flashed a tft file with a kernel and baseband and it booted. When it booted, I tried flashing the v18 kernel again, nothing happened during boot, it vibrated once and then just stalled, nothing on screen.

What should I do now?

I would like baseband 36 and the v18 kernel :)

[Xperia Arc Android Development] Riyal:
Hi! Here's a couple of selections for you...

-------------Solution #1-------------

-----------End Solution #1-----------

-------------Solution #2-------------

-----------End Solution #2-----------

The solution #1 should let you run my modified supercharger if you installed a busybox on /system/xbin & should override doom's busybox. But you won't be able to any update supercharger unless you apply the code I inserted there.

The solution #2 should let you be able to install unmodified supercharger as it replace's dooms busybox with the one you installed. But is a little bit more complicated than #1.
[Xperia Arc Android Development] Riyal:
Sure no problem :D anyways don't forget to replace the busybox from /system/xbin with the latest version. You could do that by installing busybox installer from market or replace it manually using adb+some linux commands or a file manager.
[Xperia Arc Android Development] somedude67:
Does the high boot for example 2.0ghz kernel. Does it make the phone boot at 2ghz or is that just the upper end limit when overclocking?

anyone else experiencing lags\slow downs and freeze while on v18 or v18fix1?

i had it 4 times while using the browser, it will lag and freeze and my phone would stop working untill i pull the battery out.
[Xperia Arc Android Development] DooMLoRD:
solution #2 will never work as what ever changes u do to ramdisk (/sbin and other directories) will get reverted back after reboot...

also for such script specific issues its always best to modify the script (the solution #1 which u put forth)
[Xperia Arc Android Development] Riyal:
Thanks for clarifying doom! :D Never thought the whole sbin files were stored on your modified ramdisk(Just looked at now :p). I thought it was with the autoroot script since when I took a glance at your ramdisk I saw the busybox binary at /res/ folder. I thought you were just copying busybox to sbin and install it rightaway like the way you install su and superuser :)
[Xperia Arc Android Development] isangelous:
If you are using script manager it has an override $PATH option. I dont know if it supports the /system/xbin:$PATH method, I just wrote out the whole thing myself (/system/xbin:/sbin:...) You can find your current path by running "echo $PATH" in a shell. You can probably do it via adb too:

adb shell echo $PATH

I prefer this method as Titanium Backup will restore this setting for you.

I have to report the experience of today:

I'm on stock ROM 042 with the DoomKernel #3018, brazilianwax OC 1.4 ghz, I was with 1% of battery. I putted my arc to charge and my multitouch was responding bad, like if there were other signals it was receiving.. Pages moving alone, strange scroll. No problems disconnecting the charger, just with it in.. After reaching 20% of charge, the problem disappeared totally. In the beginning I thought was the profile of SetCPU (I have the powersave governor for < 20%) but, even disabling, the problem remained...

I really don't care about this, everything lasts for some minutes, but would be interesting to know what's going wrong..

Thank DoomLord so much..

That issue happens to me too, when using the wall charger. I don't think it's kernel related, it's just how the hardware works. There tend to be some interference because the hardware's closely packed.
