@blokva: you can set it in: settings -> wifi/network -> wifi settings -> press menu button and select special/advanced button (I not know the exact names of menus in english :))

If you have working wifi/tether with gdx29 and NOT have it with gdx30, you can see: this is NOT the kernel failure, ask it in the gdx thread. :)

With minicm the wifi working good (I'm 100% sure :D), and some experienced users reported: with froyopro+alfs9c everything okay. ;)
[XPERIA X8 Original Android Development] Metallimaniac:
I can't confirm that WiFi tethering isn't working. Just checked and its fine. But it is affected by my WiFi problem. Stops working as you don't expect. =(

And to change WiFi policy, just go to the WiFi settings and hit menu button to access advanced settings. ;)
[XPERIA X8 Original Android Development] CtrlAltDelIrl:
Have you even read any of the replys to your posts? Get rid of GDX 30.

This kernel works fine with loads of roms.
[XPERIA X8 Original Android Development] Metallimaniac:
I've been very loyal to GingerDX, and I'm a fan of the work developed in its team.

Think its time to check other ROM.

Do you recommend any good rom? =)
[XPERIA X8 Original Android Development] CtrlAltDelIrl:
I use FroyoPro with Holo Launcher.. It's the best performance rom on XDA for our phones..
[XPERIA X8 Original Android Development] ->Sid:
I'm having trouble while using A2d with these kernel(alfs V9c CM7/WLAN) n gdxV30, some times apps icon isn't there and a green rectangular icon comes up also the name of app changes to the one used to build any apk i.e "com.---" and some times some apps fc, some occasion app not installed and these only happens when phn is switched off and on and to fix it i reeboot again, sometimes have to reboot 2-3 times..

Also had the same problems while trying froyo pro..

Works fine with nAa kernel same partition and swap with gdxV30 also minicm7 latest nightly and minicm10 latest nightly with nAa jb kernel..

Any one facing it..
[XPERIA X8 Original Android Development] pilu1978:
This thread is the developer thread of the kernel, not talking about "suggestions of best roms". :)

If you want maximized performance, use froyopro with wlan version of this kernel (I'm not 100% sure, but as I remember this rom need wlan module instead of tiwlan) as CtrlAltDelIrl wrote (he sometime too aggressive, but at least he write professional posts ;))

If you want maximum compatibility, use minicm7 + cm7 version of this kernel (the 99% of the apps running on API level 10).

But these suggestions is only my and CtrlAltDelIrl opinion, the choice is yours.

Note to everyone: before posting a "kernel bug" please test it with at least two different rom, and be sure: the bug is NOT the rom failure. :)
[XPERIA X8 Original Android Development] pilu1978:
@->Sid: sometime I had this problem earlier, the sd-ext partition sometime lost when the phone turned on, and need some reboot to get back. I tried with nAa kernel too, the problem not solved, so this is NOT the kernel problem. ;) I have 3 card, with a 2GB class10 card this problem never came, with a 4 and 8GB card (both is class4) the problem recently appeared. Something wrong with the a2sd script (or the mountsd script), try to use another. I solved it with direct mounting in the ramdisk, the ext partition now working perfectly (with all card). :)
[XPERIA X8 Original Android Development] Ahmad.H:
Hi,

I have made a flashable to fix the wifi hotspot issue.

Download it from here:

http://db.tt/fMuXYgaq

Please make a backup and flash it via CWM recovery.

Please tell me if this fix worked for you:)
[XPERIA X8 Original Android Development] blokva:
I did this. The connection stay more stable. Now, after connection broke it reconnect by itself (before this, it froze).

BTW the breaks occur wery often (apr. 1 per minute).
[XPERIA X8 Original Android Development] ->Sid:
I'm also using class 4, 8 gb card.. but having issue only while using alfsV09c kernel with gdx n froyo both, so currently I'm using nAa13 and gdx without any problem, so would stick to these right now, would try using other script later..

Thanx
[XPERIA X8 Original Android Development] Metallimaniac:
Hello guys, its me again.

Unfortunately, again, bad reports about my strange WiFi/Data problem.

Now I'm at MiniCM7 + and, as usual, Alfs9c. The problem is still occurring, but this time it takes a little longer than with GingerDX. During the last few days I believed that this was far from getting any problem. WiFi on on most of the day.

But, I let the phone with WiFi on overnight and boom, today I checked the blue bars (to see if I was with Google services working) and it was grey. Browsed a little, and no surfing. Checked data, same old thing. =(

Now I'm heading to the "latest" nightlies to see if problem persists.

I'm completely mind blowed with this. If it appears again, its a problem with this CM7 based roms and Alfs.

Ps: other member of xda came to me, via PM, and reported that he's is following my reports about this and have the same problem with his GingerDX V30 + Alfs9c problem.
[XPERIA X8 Original Android Development] CtrlAltDelIrl:
I'm watching closely to buddy.. As a word of advice, from my experience, when you have a hardware issue showing like this, it's always best to flash back to stock kernel/rom before moving to the next combo.

Why not try nAa's latest JB kernel with the latest CM10 nightly rom. It's much faster than I expected.

It just might work for you.
[XPERIA X8 Original Android Development] alfsamsung:
I finally after 2 days with wifi on got this wifi/data connection problem. A quick look in kmsg:

<4>[96762.823658] nf_conntrack: table full, dropping packet.
<4>[96766.817622] nf_conntrack: table full, dropping packet.
<4>[96768.440430] nf_conntrack: table full, dropping packet.
<4>[96769.874491] nf_conntrack: table full, dropping packet.
<4>[96772.858807] nf_conntrack: table full, dropping packet.
<4>[96776.853755] nf_conntrack: table full, dropping packet.
<4>[96779.821885] nf_conntrack: table full, dropping packet.

This is a problem in the netfilter and the reason is because the nf_conntrack kernel maximum number assigned value gets reached.

The common reason for that is a heavy traffic

To fix this we need to raise net.netfilter.nf_conntrack_max, that on my kernel is 13760. You can try double that and write:

/sbin/sysctl -w net.netfilter.nf_conntrack_max=27520

restart your connection and you should be online.

To make it permanent you can add it to sysctl.conf by typing:

echo net.netfilter.nf_conntrack_max=27520 >> /etc/sysctl.conf

To check your current value:

/sbin/sysctl net.netfilter.nf_conntrack_max

If you still get the error again try raising the value more.I will do some more investegation on this.
[XPERIA X8 Original Android Development] jucazastrow:
Hello guys, I'm testing nAa kernel right now, and noticed this difference compared to Alfs kernel:

So, the first pic is nAa, and the second is nAa with Alfs' libsensorpach (the same result like using Alfs)

I can use the libsensorpach on nAa kernel without problems? :o
[XPERIA X8 Original Android Development] Metallimaniac:
=)

Great! Waiting for your reports.

And again, thanks for all the work and the attention to this problem. :good:

I believe thats a question to do in nAa's thread.
[XPERIA X8 Original Android Development] Metallimaniac:
Sorry for double post...

But, i cant manage to solve this with the suggested fix.
[XPERIA X8 Original Android Development] tiestobunio:
opinion as to the kernel

I think a good kernel as nAa yet this kernel has a small flaw Jed many users complain about the large abundance of the battery

Of course, to me the kernel is working well with my roms and for +

But obviously something has to be kept short to battery on the kernel:good:
[XPERIA X8 Original Android Development] CtrlAltDelIrl:
Can you point us to all the users complaining about high battery use please?

I've been following this development very closely and haven't seen ANY complaints about high battery consumption.
[XPERIA X8 Original Android Development] Metallimaniac:
Yes. It might be the ROM that is causing battery drain.
[XPERIA X8 Original Android Development] iks8:
libsensorpach isn't only fix tor proximity sensor? I don't think this change anything with brigtness setings.

Maybe this kernel drains batery faster but has much more features and brightnes is working more smooth.
[XPERIA X8 Original Android Development] Mockingbird:
Im using it with gdx v30 and battery life is awesome , without wiping batt stats.
[XPERIA X8 Original Android Development] jucazastrow:
The second screen on the pic is on nAa kernel with libsensorpach of this thread, not in Alfs. It change the levels of "input" of light.
[XPERIA X8 Original Android Development] pilu1978:
This kernel use the original sensor drivers, the nAa kernels use modded drivers, this the reason why need to use this patch, the minicm based roms contains userspace drivers for nAa kernels, need to correct it with the patch.,

Using this patch with nAa kernels is a little bit strange idea. ;)
[XPERIA X8 Original Android Development] blokva:
I wrote about that problem with GPS using here
[XPERIA X8 Original Android Development] CtrlAltDelIrl:
And did you bother to edit your gps.conf to your country's servers or leave it on the default?

If you haven't changed that then it's your own issue. Nothing to do with this kernel.

My gps doesn't drain my battery on FroyoPro.
[XPERIA X8 Original Android Development] Romiui:
i have install v9c with update to my CM7 and i got the error with wifi !

i hope to give a reason for that =)

also am looking to ask about wifi tethering ? is it really hard to make it real like JB Kernel ?

Thanks in advance =)
[XPERIA X8 Original Android Development] blokva:
I did country optimisation, but this doesn't help me.

BTW I think this not kernel problem because on GDX v29 I haven't this problem.
[XPERIA X8 Original Android Development] Metallimaniac:
After almost one week doing some tests, the problem keep occurring. Double the value as suggested, but at some point my phone gets offline again. Now i'm doubling the second value and testing with 55040.

How much can I increase the value. I mean, there is a max number for this parameter?
[XPERIA X8 Original Android Development] alfsamsung:
@Metallimaniac I'm not sure how high,but with to many connections system will get unstable.Are u sure there is not something else wrong like an app making many connections or something. And why hold back on details?

This can maybe help in investegating

@blokva: the gps wackelock is a rom bug.It can be fixed by building with google gps source. I'm attaching my modules witch is built from cm7 with google source.Replace the 2 files with the ones in system/lib/hw. I'm not sure it will work,so make a backup first.

1.Rename the 2 existing gps*.so files in system/lib/hw to gps*.so.bak(Now you have a backup)

2.Copy the 2 new files in my added .rar and give them the same permissions as the other files in this folder.

3.reboot and test
[XPERIA X8 Original Android Development] Metallimaniac:
I tested this with GingerDX v30 with no apps nor Google Sync. Now i'm at miniCM7, with all of my daily driver apps.

I dont think i can, but ill test at this weekend with a pure installation. Let the wifi working and surfing with browser only.

How can i help with this, giving more details?
[XPERIA X8 Original Android Development] przemek4113:
What rom are you using? CM7 are almost all roms,you must tell us the name of the rom.What do you mean saying real wi-fi tetchering like on jb?

Maybe you just flashed wrong kernel.
[XPERIA X8 Original Android Development] Metallimaniac:
Im back with GingerDX v30 and Alfs9c, pure installation. Let the wifi overnight and boom, im offline.
[XPERIA X8 Original Android Development] Kumczak:
Wifi turning itself off is a GDX known bug, as far as i know.
[XPERIA X8 Original Android Development] Metallimaniac:
No, its not turning off. Read some previous posts and you'll figure out the problem.
[XPERIA X8 Original Android Development] Kumczak:
I know what you mean. But there are two different things.

Wifi disconnecting every few minutes is the kernel bug, disconnecting when you lock your phone is(was?) GDX bug.
[XPERIA X8 Original Android Development] Metallimaniac:
None of this.

______________________________

So, im here with GingerDX v30 (only gapps, sync disabled) and a logcat where the problem happens. Didn't change the parameter to 'solve' the problem.

Should i post it here?

2. File gps.delta.so doesn't present anywhere in my phone.

what need I do with different location in 1. and absent file in 2.?

@alfsamsung or anyone...does the kernel supports loop devices?:confused:
[XPERIA X8 Original Android Development] CtrlAltDelIrl:
Why not try it if you have a readable image file..

The command would be as follows:

mount -o loop /sdcard/myimage.img /mnt/wherever

Just make sure the destination directory exists beforehand. You may need to be su to issue the mount command.

Let us know how you get on..
[XPERIA X8 Original Android Development] fotak-x:
I tried

losetup /dev/block/loop2 /sdcard/img.img

but I get : losetup: /dev/block/loop2: No such file or directory
[XPERIA X8 Original Android Development] blokva:
I have tested this solution 2 days. And it seems the problem is solved!! Thanx a lot!!!! :good:

I will test it some time more with different programs.
[XPERIA X8 Original Android Development] CtrlAltDelIrl:
Unfortunately Android doesn't do error reporting on the same level as linux so "No such file or directory" cannot be used to decypher the error.

Did you not try the mount command?

---------- Post added at 03:28 PM ---------- Previous post was at 03:18 PM ----------

Have a look at this script for an idea. This is a script to mount Linux inside Android so it does work, just not sure if this kernel supports it.
[XPERIA X8 Original Android Development] fotak-x:
yeah i tried "mount" command but its same problem like losetup

script...it use same method for mounting img to loop device (losetup /dev/block....)

mounting loop device has worked great on stock,nAa v11 and alfs v6-8 but not on curent alfs kernel :eek:
