I would say the class of the card, a potential hardware problem (card pins/connectors/card hinge) or I would ask you if it was plugged in the computer with sd storage activated. If it was please take note that the phone can't read files on the FAT partition at the same time as the computer

I've been using DJ's kernel for a long time with a 2gb card that came with the phone, class unknown, and with my current 16 gb Scandisk class 10 but I never had this problem unless plugged in, storage mode.
[Optimus One, P500 Original Android Development] CosmicDance:
Of course, I experienced this problem when the phone wasn't connected to the pc, I do know that once connected to the pc, the files can't be accessed by android..

It beats me, Ive never had this problem before, I even unmounted and mounted the sd card via settings and even restarted the phone to test.

I will flash the latest cm7 nightly that comes out tomorrow after doing a full wipe and see if it solves the problem... Probably its a coincidence with the kernel.
[Optimus One, P500 Original Android Development] CosmicDance:
Attached the logcat...
[Optimus One, P500 Original Android Development] carrthee89:
@CD I don't think its a kernel related problem .. try using ur SD card on some other phones .. I ve faced the same problem sometime before .. just get a new one.. :):)
[Optimus One, P500 Original Android Development] eigokyoukan:
Something you can try:

I had this issue about a year ago. I would throw files on the SD card and they wouldn't show unless I copied twice or rebooted, as well as sometimes apps on my SD-ext partition acting wonky.

For ****s and giggles, I completely wiped and re-partitioned my SD card. No problems after that, leading me to believe something I did messed with the partitioning. Yes you will lose your data on the card, and no I can't guarantee it will fix your problem. Just that your issue sounds similar to what I had going on, and that fixed it for me at least.
[Optimus One, P500 Original Android Development] CosmicDance:
I'll try what you suggested... Probably something got messed up recently... I keep transferring files now and then, probably something got corrupted... Will check the card through windows error check utility...
[Optimus One, P500 Original Android Development] CosmicDance:
I downloaded the latest CM7 nightly(5th August),wiped the cache and dalvik cache and flashed it. I didn't experience any sd card issue, however after i flashed the kernel, I'm again experienced the sd-card problem - JetAudio can't scan the sd card, the OS isn't able to detect the ringtones... But PowerAMP is working flawlessly, MXPlayer too is able to detect and play the files... I'm really perplexed...

I would have assumed that the fault lies with JetAudio only, but the fact that the OS itself isn't able to use the ringtone from the SD card, suggests that there is some other factor occuring here..

I won't report this again, as i feel this is a minor bug and can be overlooked( by placing the ringtone in the /system/media/rintone and use poweramp for the music files)

I must say that i could feel the difference in the stock CM7 kernel and Dj's kernel. Dj's Kernel is brilliant and really smooth.:good:

Hmm anybody has the gps wakelock??

It doesn't get switched off after switching on GPS

A wakelock remains and kill the battery :(

I'm on latest TA vsync on version with Ginger Snap 1.3
[Optimus One, P500 Original Android Development] eigokyoukan:
No I am not. But I am getting a different one.

On hephappy's ICS with ta vsync off, and I'm getting *backup* as a wakelock for about one hour out of 8 hours overnight. It doesn't really drain battery though so I haven't been to pressed about it.

Otherwise 2.5.4 ics version is rockin my socks off!

Hello everybody

I'm ill (have a cold), but its getting better. Thats why I didn't work on kernel the last days.

Also lot of things to do at work. So I was late at home the last days.

But now its weekend :D

Some update of the things I try to understand:

- Why does my 3.x kernel not boot? :confused: There are no compile errors.

- Why does my v2 kernel not boot when I use linaro toolchain? :confused: (I think all necessary changes are included)
[Optimus One, P500 Original Android Development] lolphirae:
Because that ricer toolchain is heavily broken. Do not use it.

[Optimus One, P500 Original Android Development] franshie06:
is this new version better than v2.5.4 in terms of battery life? thank u..:confused:
[Optimus One, P500 Original Android Development] vlt96:
Yep... nokia's....

I can't understand people saying "battery is better here, worse there"...

Battery is influenced by wakelocks, if the Rom/kernel has none, battery should be the same, unless you have apps that cause wakelocks or have wifi and other stuff on

So can you stop spamming about battery people??

Hey DJ, I felt that in latest versions, 2.5.2 onwards, scrolling isn't that smooth as before in GB ROM's, though battery backup seems to be increased a bit, please include a version with improved perfomance instead of battery next time if possible.
[Optimus One, P500 Original Android Development] thatnextdoorboy:
Cm7.2, 5.08.2012 nightly, about 60 apps linked to market.

I was at about 65% battery I think when I flashed v2.5.5. It went down to 49 in about 1h when I decided to revert to 2.5.4 and battery usage returned to normal. Will flash v2.5.5 again tomorrow with the new nightly, being that I always wipe everything and do a clean install with full battery just to be sure, and will come back on this.
[Optimus One, P500 Original Android Development] eigokyoukan:
I'm definitely don't have this issue with 2 5.5.

8 hrs overnight gave roughly 5% drain tops. I'm on second day with no charge.
[Optimus One, P500 Original Android Development] thatnextdoorboy:
I don't have it either anymore. Guess it was some interference with a app or something or from the fact that i didn't do an overal clean instal.

Stellar battery life as usual.
[Optimus One, P500 Original Android Development] eigokyoukan:
Cool to hear! Battery life on this kernel is quite amazing.

Been using your kernel on hephappy's ics. No bugs so far from kernel side, and performance is damn good. Battery life... always a day and a half for me with 30% or so to spare. I do use my phone lighter than most, but that always includes 2 hour phone calls with the GF. Besides that just light texting, browsing and gaming.

Nothing to complain about at all! Thanks for all the hard work bud.
[Optimus One, P500 Original Android Development] DJNoXD:
SD-Cards are stupid things sometime.

Yestday I installed cm9 (hephappy's). Today my sd-card decided to wipe itself. :silly:

So I orderd a new one (16 samsung class 10).

The only good thing about, l learned how to use google drive from titanium backup.

So I will never loose my backups again. :fingers-crossed:

What's bad with Google Drive in the first place is no Linux support. And some minor things like not following symlinks etc.

I'm on ICS. I wiped cache, dalvik-cache and flashed v2.5.5 for ics. My phone booted, prompted for SIM card unlock and showed the unlock pattern screen. It was quite laggy, but I got to my launcher. Then it stopped responding to touchscreen and after a while it rebooted. I did this for over three times, then pulled battery out and flashed a different kernel.

What am I doing wrong?
[Optimus One, P500 Original Android Development] DJNoXD:
I would say nothing.

Thats the same way I have done, but without the problems you have described. (But I don't use sim card unlock)

Was there anything shown in logcat?

few questions

does this kernel work with Arjen's CM9 weeklies? I've been using CodeAurora kernel from thachtunganh, but since he stopped the development, I am looking for other kernel to use.

How is the camera flicker with the ICS version? In CA kernel there was none, in the CM9 stock kernel there is a lot of flicker at the same OC speeds. Does Bluetooth headset (I am using stereo) work also for calling? I am having trouble with BT calling under Arjen's CM9.

I don't understand why it feels slower. :confused: (If you are searching old versions, you can find them also at googledrive -> history)

I am thinking about creating a minimal kernel, without all those modules compiled inside.

Maybe it will solve that it feels slower.

Than everyone can decide if fuse, ... is needed or not.

can you fix the sd card problem with the kernel?

with 2.5.4 and 2.5.5 i have same problems with the sd card unexpectedly unmounting when i receive calls or unlock the phone.

after that i instaled kernel pp v.1.7 and the problem is gone, no more sd card problem.

Dear DJ,

I am sharing my observation, My sdcard is class 10 sdcard from transcend, 16 GB. When i was on Amenora no problem with the kernel, but when shifted latest CWM touch recovery 5. 0. 2. 7 got the problem of random unmounting of the card. Still investigating, will post logcat if this happens again.

2. i have dont see the logcat(now i use another kernel(pp v.1.7) stable for me without sd card problem)

3. sometimes when i unlock the phone the sd card unexpectedly removed and same too when i receive the call the sd card unexpectedly removed and because that my phone reboots.

4. it happens every day several times.
[Optimus One, P500 Original Android Development] rr0yy:
CWM 5.0.2.7 has many bugs.. try the older version 5.0.2.0 and see if the problem persists.

And are you guys sure these problems are related to kernel. Im using 16gb class4.. never had

any problem. Make a nandroid backup.. flash the latest CM.. see if this problem shows

again.. if no problem. Flash this kernel and observe.

Another thing.. do you use link2sd or a2sd??

If it is due to DJ's kernel.. its definately the kernel's I/O sheduler, nr_requests, buffer size of

queue depth and many things which i guess doesnt support class10 storage.

@kanad.. flash kernel v2.1.1

and tel if this issue happens again!

smoothest kernel ever that I felt was ta gb 1.02 but, it has the white noise bug on unlock which restricts me from using it :p
[Optimus One, P500 Original Android Development] :
@DJNoXD, the kernel is slower than original cyanogenmod kernel
[Optimus One, P500 Original Android Development] DJNoXD:
I could imagine that lot of the additionl modules could be the reason for that.

Advantage of building them into the kernel: You don't have to care about loading and the modules could be a little bit faster.

Disadvantage: Maybe more ram is used. Performance lesser.

At the moment I think about this:

- Creating the normal kernel + a kernel without all those additional modules build in.

- Creating kernel without modules (except wlan) + additional zip including all modules.

I am prefering the second solution.
[Optimus One, P500 Original Android Development] DJNoXD:

[Optimus One, P500 Original Android Development] nikola_79:
2.5.5 kernel is BEST, and if you think is slower or ta gb1.02 is better DONT USE IT and stop with stupid comments slower etc. if you want speed kernel overclock to 768mhz,governor smartassv2 and here you are you have speed.

For me 2.5.5 is BEST KERNEL

SMS lost after phone hangs up

I have really strange behavior with this kernel (doesn't happen with the stock CM9 kernel):

sometimes the phone becomes unresponsive. I think, that it happens mostly when I connect the charging cable. It seems to die totally, but the WiFi icon blinks, so it is not totally dead. After that I have to take the battery out.

Sometimes after this brutal reboot, all SMS messages are missing, sometimes even all aco****s info.

Any ideas? Unfortunately I have no logs. I did lower my OC, but that is definitely not the reason.

I'm not 100% sure if the change you are talking about was the reason that fixes GPS wakelock bug. Thats why I did not commit to cyanogen.

[Optimus One, P500 Original Android Development] DJNoXD:
Hello kokesh, hello karthiknayak94

I will take a look at francos changes and try to find if there are some more patches for better battery life.

Maybe I will write franco and ask him if he can tell me something about his battery and performance tweaks.

About performance. This will be the next thing I will try to improove. I will go through all the changes I have done and check them again. You can see in changelog that I have started (for example vm_swappiness).

A month ago if have tried teathering over wifi using my phone as host and my tablet as client. For me it works. I have not tried USB teathering.

Which kind of teathering did you use, ...? Please give me some mor information. I can take a look at and try to find if something can be done.

About the whitescreen bug:

I'm also on cm7 RC1. I think can see white screen too. But the time it can be seen is very short. So I have to watch my screen exactly to even recognize it.

How worse is is on your phones?

But I can try to find out, where it comes from.

I am going to ask Roq and thachtunganh if they also had this problem anf if yes how they fixed it.
[Optimus One, P500 Original Android Development] Lycan:
The 2nd one is the touchfix which franco had implemented in 08122011

The 1st and the 2nd are almost nearly the same.

But personally i always like franco's ts driver
[Optimus One, P500 Original Android Development] DJNoXD:
Can you exlpain me what axis inversion helps to improove?

I have seen this often, but never get to point where it helps. Is it an improovment only for multitouch?
[Optimus One, P500 Original Android Development] Lycan:
Its a bug in the original touchscreen driver.

Multitouch works unless both your fingers are in the same line.

however, i think that does work sometimes (check this out http://www.youtube.com/watch?v=jnPsY6Z6Uu4) but it only does when the cpu is not under stress.

While playing games like pes and nova, its nearly impossible to move while you shoot.

Thats true, but 1 or 0 should not make a big difference.

0 tells kernel that resources should be kept in RAM if possible.

For me the performance was a little bit higher with value set to 1.

Test it yourself and tell me your results.

By the way, is lionheart working better now?
