I have faced this problem with razil's jb patch. Have you also installed that patch ? If installed then make fresh install of rom without patch. :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] najodleglejszy:
CM10 with this kernel is really smooth, but:

1. I can't make FM radio work

2. random reboot after random reboot

3. the boot time is pretty long, the phone spends a considerable amount of time on nAa logo.

I admit I didn't try raising minimum freq and I'm back to LuPuS until the FM radio works.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] seidler2547:
I've given up for now on this kernel. I'm now on the MESA unified kernel v4.4 (Linux 2.6.32.x) and although BT doesn't work on it it's just stable and fast, and that's ten thousand times more important! Even with overclocking no reboots. With this 3.4 the reboots would not stop no matter what I tried, upgrading BB to .77 or raising the min freq didn't help at all.

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Vynikal:
It is strange. Even on the same ROM are many people reporting issues. I personally haven't got any reboot or any single wifi interruption with v02, neither with v03. Using Mike's CM 10.1. It isn't caused by basebands or overclocking. There is something different.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Lucaviola:
Mr. nAa, will you build a ROM which use this kernel as a base? I hope it would be perfect combination..
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Vynikal:
Yes, MiniCM on Xperia 2010 was awesome :D.

Does anyone have problem with GPS. My GPS can't even find one satellite.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] hunfatal:
I've raised the minimum freq, still reboots sometimes. Also my battery is drains extremely fast if Wifi is turned on and connected to a network. (Drains to 16% from 100% during 8 hours). Otherwise the speed is awesome! I hope this bugs will be fixed smooth :)

I'm using FXP221 on Mango.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] novicebg:
Is your aGPS turned on by default? If so, turn it off! If it is off, wipe cache and try again.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kv1dr:

The kernel is good for any Rom JB.....but it's a bug with me. ..

1. It's the heavy battery drain when i use opera mini with 3g or play some small game or capture some pic.... ... but in sleep mode, it's rather goood.//// can u fix that/.. i try many rom..:P

2. Sometimes, i unlock my screen, i can't touch anything,,, dead screeen and it auto turn off device and i have to turn on again and lost ~10% of battery
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kv1dr:
Yeah, I know what is aGPS, I just didn't know how to disable it.

I set Default_agps_enable to false, rebooted, cleared cache, but GPS still doesn't find any satellite.

Oh, I am so stupid. I was in house and off course I had to go outside.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] alliktaavo:
Excactly the same here! Wifi drain is huge for some reason. Raising the min.freq helped, but not enough, unfortunately. Tried to ignore the bugs, but I got some serious reboot cycles. Weird part is, that the reboots went almost exponentially worse as time progressed.....at first maybe once/twice a a day, at some point a few times a day and then suddenly up to ten times a day without cycles (boot up, and reboot if I try to continue what I did before).

Back on lupus for the moment, now my phone seems unbearably slow compared to nAa's work!

Hope you find out what's causing this ! :D

bluetooth issues

I have been using this kernel (v3) with Ultra Slim CM10 v2 ROM for a couple of days now. It is really fast. Maybe the fastest config my good old LWW has ever been! With this awesome kernel and Project butter of JB its like, for the first time I'm seeing smooth animations and transitions of android! Thanks a lot to nAa for making this possible!

Everything else has been fine for me but bluetooth is having issues. I saw posts in this thread previously saying that bluetooth is working. But for me BT turns on and off and my device is discoverable. But if I try to send or recieve something its always stuck at 0%. Pairing also doesn't work. Nothing comes up in my laptop if I select to pair with it from my phone. I have also tried sending and receiving from two other phones but same result. Is there something more that I need to flash to fix bluetooth? (like the wifi modules) Is there anyone here for whom bluetooth is working with Ultra Sim CM10 v2?

And for the general discussion I did have 2 sudden reboots within an hour of flashing the ROM. But since then I haven't had a reboot for around one and a half day. Fingers crossed :D :D (I didnt change minfreq or anything)

first i would like to thank nAa for the great job

the in-kernel boot animation is wonderful

i used the traditional tools on windows for unpacking this kernel to see whats going inside especially the boot animation files (series of image files)

but i failed using cygwin

$ ./extractboot bootnaa.img

Page size: 2048 (0x00000800)

Kernel size: 4446120 (0x0043d7a8)

Ramdisk size: 3507483 (0x0035851b)

Second size: 0 (0x00000000)

Board name:

Command line:

Writing bootnaa.img-kernel ... complete.

Writing bootnaa.img-ramdisk.gz ... complete.

gzip: ../../boot.img-ramdisk.gz: No such file or directory

cpio: premature end of archive

i also tried to separate the .gz file manually starting from 0x1F 8B but the resulting file was unrecognizable buy gzip nor 7z ..

so how to unpack this modern kernel ?? please help
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] novicebg:

How to unpack

i'v tried to unpack this kernel using lzo extractor but i failed, it says that file not in lzo format...

i opened the image file using HEX editor trying to separate the kernel and ramdisk files but i couldn't instead i found this written inside the .img file:

"-- System halted.Attempting division by 0!.Uncompressing Linux.... done, booting the kernel...decompressor returned an error.invalid distance too far back.invalid distance code.invalid literal/length code.incorrect header check.unknown compression method.invalid window size.invalid block type.invalid stored block lengths.too many length or distance symbols.invalid code lengths set.invalid bit length repeat.invalid literal/lengths set.invalid distances set.incorrect data check.Out of memory while allocating output buffer.Out of memory while allocating input buffer.Out of memory while allocating z_stream.Out of memory while allocating workspace.Not a gzip file.header error.read error.uncompression error.."

try this kernal its based on nAn kernal by mikeioannina :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] doctorace92:
This is a lzo compressed(instead of gzip) kernel image. So you have to use "lzop -dc" instead of "gzip -dc" to extract the initrd. I have seen the source of the animations. Just like boot animations where there are multiple pngs, here there are multiple rle files for animated boot logo.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] johnnyx83:
i finally figured out how to unpack/repack this kernel:

to unpack bootnaa.img-ramdisk.lzo file :which is the separated file from .img (hex signature 894C5A4F000D0A1A @ 0x43E000 )

using cygwin type:

$ lzop -d bootnaa.img-ramdisk.lzo | cpio -i <bootnaa.img-ramdisk

////-----------------------------------------------------------------------------------------------------------------------------------------

to repack new-ramdisk.lzo assuming DIR is the extracted/modified ramdisk contents..

cd DIR

$ find . | cpio -o -H newc|lzop -9 > ../new-ramdisk.lzo

then you need to append the original .img file with the new-ramdisk.lzo just created, using hex editor at 0x43E000.

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] seidler2547:
How I made this kernel A LOT more stable:

short version: flash the attached ZIP file.

Long version: I remembered a bug that came up with the HTC Doubleshot some time ago. The kernel sets the frequency of the GPU clock too high, causing it to overheat/crash (sometimes randomly power off). So my solution is to limit the GPU clock to 192 MHz (down from 237.5 I think).

Caveat: you get lower scores in 3D benchmarks.

Benefit: almost no random reboots (for me).

What the ZIP does: it adds a file into /system/etc/init.d which gets executed at startup. This file contains just one line which writes the value 192000000 to a file in sysfs (/sys/class/kgsl/kgsl-3d0/max_gpuclk).

If someone else could test that if you also had too many reboots... Maybe this will fix this issue for some.

Stefan
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] nimbold:
It really helps!

Just flashed it on Mike's and all ok.

Even overheating problem is gone! No reboots till now (about half a day).

Thanks mate ;)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Mysteryagr:
won't that affect 3D games performance?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Somyab:
Of course yes but it would be better using phone without reboot instead of low performance in some games which we play only often
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Mysteryagr:
Limiting the GPU clock doesn't solve any issue for me.

Same reboots happens, while using FB app or browsing the internet or doing heavy multi-tasking.

What I gain is limited GPU clock and the positive results is NOTHING!
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Vynikal:
Confirmed...no good efect...:(
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] seidler2547:
And do you have /proc/last_kmsg now? Because I wouldn't before this fix, and now, if it reboots, I have. I also raised the CPU voltages with System Tuner, because I would still get 2 or 3 reboots a day, and it helped to reduce it even further. I'll wait and see how it behaves now.

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] cajhin:
Turn off wifi when you can. It is the reason for most reboots.

Unfortunately, it is very very hard to fix it.

If you can (you have a data flatrate), rename the two wl* files under /system/lib/modules/

That stops _all_ wifi-related reboots.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] wawan20:
If I rename that , can I still use wifi again ????
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] cajhin:
You'll first have to rename the files back, and reboot.

If you need wifi sometimes, then just turn it on/off with quicksettings. It's not 100% but with a little luck you might be ok.
