Experimental kernel 3.16 for Android-x86 (READ WARNING FIRST)

[pstglia]

Hi everybody,

I'm sharing with you an experimental kernel 3.16 modded for Android-x86.

Basically, the job was diff released kernel.org src with android x86 kernel, compared the changes and created patches to apply on 3.16.

Also used experimental kernel 3.14 released from AOSP to ensure which changes were related to Android.

Some extra changes were required in order to compile and run it (listed some of then in the end of this post)

In the systems I tested (AMD A10 5800K / Celeron E3300 with Nvidia GT630) most of basic functions worked (watching videos, surfing at Web, etc). 

Nouveau performs a bit better with this kernel than the previous one (3.10.x), due the driver changes inside kernel. I noted a big difference playing videos.

Currently, wifi network is not working (unable to store keys /authenticate - appears to be related to wpa-supplicant). Haven't tested with open networks.

Wired network is working.

WARNING: If you want to give a try on it, keep in mind that:

 - These changes may contain bugs that can DAMAGE your hardware and cause DATA LOSS.

 - Some hacks were made to bypass some security. So this may EXPOSE your machine and network.

Use it AT YOUR OWN RISK. YOU WERE ADVISED

********************************************************************

If you want to build your system with these changes, here's 2 alternatives

1) Applying patches:

1.1) Download kernel 3.16 source (from kernel.org) and unpack it 

1.2) Copy the attached patches to the download kernel directory

1.3) Apply them with "patch -p0 < patch_file_name". Each patch will modify files from the correspondent directory (kernel, arch, drivers, etc)

1.4) Copy Android.mk file from Android-x86 kernel dir (ANDROID_SRC/kernel) to your downloaded kernel directory

1.5) Replace current Android-x86 kernel directory (ANDROID_SRC/kernel) by your patched 3.16

1.6) Clean previous build and start compilation

2) Ready modded kernel

2.1) Download modded kernel source from here:

https://drive.google.com/file/d/0BxO6THtB865fNFFRYzdCbDM2X3M/edit?usp=sharing

2.2) replace your existing kernel dir (ANDROID_SRC/kernel), clean up previous build and kick in.

* * * 

There is an ISO I built to test on my hardware. It's using mesa 10.1.5 and is intended for Radeon (non CGN) and Nvidia GPUs (This won't work for Intel GPU users)

https://drive.google.com/file/d/0BxO6THtB865fZXM0bER4TUdvUlk/edit?usp=sharing

* * * 

Some of the "ugly" hacks made:

 - net/ipv4/tcp.c: Commented reference to rcv_saddr on ipv6 code

      /*s6 = &inet->pinet6->rcv_saddr;

      if (ipv6_addr_type(s6) == IPV6_ADDR_MAPPED)

      continue;*/

 - drivers/input/evdev.c: Removed call to wake_lock_destroy

/*if (client->use_wake_lock)

 wake_lock_destroy(&client->wake_lock);*/

- Disabled NETFILTER_XT_MATCH_QTAGUID parameter on kernel config to avoid errors related to xt_qtaguid.c

- drivers/gpu/drm/drm_drv.c: ignored return from drm_ioctl_permit (permition check for drm ioctl, based on extra permissions, like CAP_SYS_ADMIN/DRM_AUTH

I attached a file with some personal notes: "estudos_loucos_kernel_android_20140809.txt" (In Portuguese)

Thanks for pointing this out (I'm using WPA-PSK /WPA2-PSK with a TL-WR841N router + Ralink corp. RT2760 Wireless 802.11n 1T/2R pci card). 

Will check if there's a fix for this on 3.16.1. In last case, I'll try to debug it.

Currently trying to put all this mess on git :)

Thank you for putting it on the github.
However, I saw it's a big single drop.
It's not easy to see what changed.

Could you please do it in this way:

* Clone the vanilla kernel
(e.g., https://github.com/torvalds/linux )
* Apply each patch separately, including
Google's and yours (if any).

In this way it could be reviewed more easily.

Forked Torvalds kernel, applied patches to modded / created files and pushed them (branch name is v3.16_android):

https://github.com/pstglia/linux

Could you check it please?

[Snake Eyes]

I tested your build in my system (i3 540,ATi 5770), and it is really fast one. Antutu jumped from 52837 (original 4.4-R1) to 66400.
I am also having that WPA bug, but it connects to open wifi.

The results so far are quite nice, hope you continue developing.

[rbg]

FYI-

got to re-test today after upgrading to kernel 3.16.1, then rebuilding

same WiFi issues for me.............

[pstglia]

Will try to map the problem.

Have u found any other issues?

[Mauro Rossi]

Trying to build with kernel 3.16...

Do I need to leave the kernel/android folder to successfully complete the build, isn't it? 

 

In my previous attempts, I was doing the fist kernel build by providing 3.10 version of my_defconfig,

that should induce the kernel building with default settings for new 3.16 features.

I'll try and I'll report back the results

M.

[pstglia]

Do I need to leave the kernel/android folder to successfully complete the build, isn't it? 

Hi Mauro,

You can do this if you don't wish to build all android src again:

1) Replace entire ANDROID_SRC/kernel by this patched one

2) Remove the previous kernel build:

# removing img files:

cd $OUT

rm -f ramdisk.img install.img kernel system.sfs initrd.img android_x86.iso 

rm -f ./obj/PACKAGING/systemimage_intermediates/system.img

# Remove obj files:

cd obj/kernel

rm -rf *

# Copying new .config

cp ANDROID_SRC/kernel/arch/x86/configs/android-x86_defconfig ./.config

# remove modules/firmwares

cd ../../system/lib/modules/

rm -rf 3.10.52-android-x86/

# remove libwebchromium (I had to remove it - it is somehow linked with kernel and was crashing for me before rebuilding)

cd ../../../obj/SHARED_LIBRARIES/

rm -rf libwebviewchromium*

3) Go back to ANDROID_SRC and start compilation:

make -j5 iso_img (or a variant of this)

no have only been concerned about WiFi stuff.....will add some gapps this week

and if ok will run some games....any suggestions on other stuff to check out/verify????

also should I try 10.1.4 mesa intergration??

If you can, please check performance and Stability in general (compared to 3.10.52)

 

also should I try 10.1.4 mesa intergration??

 It depends your hardware... if you have an Intel IGP, keep it unchanged. 10.x Mesa version has problems with classic drivers. Emil Velikov and Mauro Rossi are trying to make this work.

If you are using radeon/nvidia, Mauro has generated patches for 10.2.3 and even 10.3.0. Check this:

https://groups.google.com/forum/#!topic/Android-x86/WkwkrP38M1o%5B101-125-false%5D

A last note: Checked that loading "ctr" and "ccm" kernel modules we are able to auth wpa2. However, there's still problems trying to access network.

Maybe another crypt kernel module which needs to be loaded... Still digging

Thanks,

pstglia

[pstglia]

Hi Folks,

Solved the problem with wpa2 auth (at least in tests I executed on my hardware) making some crypto modules built in instead of modules (just to avoid explicit loading on scripts)

Note: To keep a cleaner track of changes, a merge/rebase is required between regular kernel source and android source. 

I did it in a very manual way (used diff and KDE's gui Kompare ), so it's not easy to see the changes made by Google and our changes the way this git is today.

I'm not familiar with merge/rebase, so if someone could help I'll be thankful

[Mauro Rossi]

Hi, great news!

Can I ask some further questions? Just to undestand more about kernel folder and rebuild from scratch. I use ccache to speed-up

Do I need the existing ANDROID_SRC/kernel/android folder?
Android.mk file is necessary, but can I use the exact same file present in 3.10.52 current kernel?

Regarding android-x86_defconfig file how was it generated? Using kconfig merge scripts and merging necessary and recommended kernel config lines as per kernel/android files and instructions?

Thank you, sorry for asking, but I'm trying learn and fix these concepts.

Mauro

[pstglia]

HI Mauro

 

Do I need the existing ANDROID_SRC/kernel/android folder?
Android.mk file is necessary, but can I use the exact same file present in 3.10.52 current kernel?

ANDROID_SRC/kernel/android is not really necessary. It's supposed to contain a minimal required configs to build an Android system. However, if you ensure your arch/x86/configs/android-x86_defconfig has all necessary options enabled, this is not needed.

Android.mk from 3.10.52 can be used. Kernel base dir structure is the same on 3.10.52 and 3.16 (some minor differences).

There's only one Broadcom driver download inside this... Not sure if has to be changed...

 

Regarding android-x86_defconfig file how was it generated? Using kconfig merge scripts and merging necessary and recommended kernel config lines as per kernel/android files and instructions?

Here's how I generated mine:

 - Got android-x86_defconfig from 3.10.52 and copied to $OUT/obj/kernel and renamed it to .config

 - Under ANDROID_SRC dir I run a "make -C kernel O=$OUT/obj/kernel ARCH=x86 oldconfig" to import the common settings from 3.10.52. For the new parameters, I choose the default answer

 - When finished, I run a "make -C kernel O=$OUT/obj/kernel ARCH=x86 menuconfig" to check extra drivers/parameters I want to enable (e.g enabling crypto modules)

 - Finally, I copy $OUT/obj/kernel/.config to arch/x86/configs and rename it to android-x86_defconfig

To use the merging way, suppose you are in the vanilla 3.16 branch
and want to merge the Google android-3.14 branch:
(assume both branches are already in your repository.
if not, use git fetch to get them)

git merge android-3.14

then use 'git status' to check which files
have conflicts, and edit them manually
to remove the conflicts.
Then use 'git add filename' to add the files
you resolved the conflicts.
Once all conflicts are resolved, you are done.
Try to build it and fix errors if any.
Use 'git commit' to commit it.

The rebasing way is almost the same, except
you have to resolve conflicts in each patch separately.
Could be simpler but take longer time.

What compatibility?
If you meant arm translator, where's my water
is a good app to test.
(cut-the-rope is not since it already supports x86)

If you meant then OpenGL ES,
I suggest you run benchmark apps like Antutu.

Still no luck with built in WiFi ... :( Tried rosewill wifi dongle ... works for like 2-3 mins, gets dc and system becomes highly unstable. Question : Does r2 works with AMD systems? What kernel x Mesa does it use?

can you tell the brand/model of your wifi card?

Question : Does r2 works with AMD systems? What kernel x Mesa does it use?

When u say AMD, you mean graphic card or CPU?

If graphic card, if not a Radeon CGN (like R7, R9), should work (I have a A10 5800K, works ok). 

It uses Mesa 9.2.0 + kernel 3.10.52

[Mashnoon Ibtesum]

Wifi card = Broadcom BCM4313 802.11 BGN and I was talking about AMD A8 APU :P I managed to boot up and run 4.4r1 for a while but then after a while I start to get this graphic glitches and eventually my system stops responding :( I tried a modified iso of rc1 with 10.1.1 which works fine btw :P

On kernel 3.10.x, BCM4313 is enabled by Broadcom proprietary driver "wl". I haven't included this on 3.16 and brcmsmac (the opensource driver) is disabled on kernel config (requires proprietary fw to work)

Will try to include it later... But you are free to do this by yourself :)

[Mashnoon Ibtesum]

Can you provide me quick instructions or point me to a resource ? :)

[pstglia]

Can you provide me quick instructions or point me to a resource ? :)

To make your changes, you'll have to build an Android-x86 compiling environment. Check this instructions carefully:

http://www.android-x86.org/getsourcecode

Notes:

 - Don't forget to read  http://www.android-x86.org/getsourcecode and install all the dependencies listed

 - Use jdk6 (Oracle distribution) and not jdk7 (It's a common mistake)

After building your environment (and downloading all Android src with "repo init / repo sync") you can change code and compile stuff

In your case (enable broadcom for kernel 3.16), download modded kernel src, replace ANDROID_SRC/kernel 

After this, you can download the Broadcom proprietary firmware:http://www.broadcom.com/support/802.11/linux_sta.php and check readme file for more details

To build your kernel, read this first:

http://www.android-x86.org/documents/customizekernel

All this procedure may seem complicated, but this is not. You just have to read all the docs with attention, have patience and don't give up if something goes wrong.

May the force be with you!

Hi,

I forgot to mention about a strangeness, when booting on Intel chipsets the Mesa driver loaded with 3.16 kernel builds is vmwgfx gallium driver,
which seems to be treated as a valid EGL driver and takes precedence over i915/i965.

Is it correct that in order to avoid this completely, I could simply remove vmwgfx from BoardConfig.mk file?

Alternatively: which is the exact moment/way to use the command: export EGL_DRIVER egl_dri2?
To be launched at first prompt, second prompt or inserted in the init.sh script hal_gralloc() function?
Is the syntax correct?

I'm not able to force dri2 Intel drivers, because I'm doing something wrong.
Thanks

Well, I think vmwgfx is not enabled in the current source tree,
unless you add it yourself.

You may add it to the early-init stage of init.x86.rc.
Actually it's already there, but commented out:

# export EGL_DRIVERS egl_dri2

Just remove the #

I tested this build on my Sony Vaio Pro 11. All seems to be working well except GPS. Also Wifi works, but does't always come back properly after suspend/resume. On the positive side, the suspend stays suspended as opposed to the 4.4.2 r1 build which keeps waking up every few seconds.

[Mauro Rossi]

Hi,

in order to build ISO images you can refer to AOSP build environment setup instructions and expecially to Android-x86 website source download and build instructions.

Remeber to install  Oracle Java 6 and not version 7 for building Android-x86 branch kitkat-x86.

In order to add gapps on ISO, after completing the build without gapps, you can use the attached script,
provided that you have an ISO image already having gapps.

0) download attached gapps.sh to your user Downloads folder
1) set gapps.sh attribute/permission with executable flag
2) move downloaded ISO with gapps to your user Downloads folder
3) if you use android-x86-4.4-r1.iso name, also by renaming any other 4.4.x ISO, you don't need to modify gapps.sh script
4) check your source directory because the script declares it with this line:

export ANDROID_BASE_SRC="/home/utente/kitkat-x86"

5) edit previous line by updating with your source folder

6) launch ./gapps.sh

7) rebuild iso_img

Cheers

Mauro

[Mauro Rossi]

Correction to step 3) statement, you will have anyway to modify gapps.sh script according to step 4) and 5) instructions.

[rbg]

what happened to etc/permissions & frameworks & lib changes from gapps system folder??

reason I ask is I push system from gapps,zip for given build through adb to my device and

it all works fine....your method doesn't move any of the files from permissions/frameworks/lib and it all works fine as well???

good to know if a fact........!!

[Mauro Rossi]

Hi, 

I tried once the method of copying entire /system folder extracted from a gapps archive (gapps-kk-20140606.zip) to proper out/target/x86/ but I had problems

the additional apps were not visible.

This procedure was suggested to me, but I'm not 100% aware of its completness, we can complete it together

Looking here: https://groups.google.com/forum/#!searchin/android-x86/google$20apps/android-x86/11n-3m1vpW4/ThkxwaeXQqEJ

also these files were suggested for copying to target with ICS, I don't know if there were changes in JB, KK:

system/etc/permissions/features.xml
system/etc/permissions/com.google.android.media.effects.xml
system/etc/permissions/com.google.android.maps.xml

For gapps you can do something like this:

Note: remove also $OUT/./obj/PACKAGING/systemimage_intermediates/system.img

To blacklist a module, you can edit device/generic/x86/modules.blacklist and add the module you want. Ex:

I have attempted to recompile the android 5.0 sources with this kernel. When compiling, it errors out saying No rule to make target `out/target/product/x86/kernel', needed by `out/target/product/x86/android_x86.iso'

Any idea's? - As soon as i delete the sources on the new kernel, and replace the default it compiles OK.

Hi everybody,

I'm sharing with you an experimental kernel 3.16 modded for Android-x86.

Basically, the job was diff released kernel.org src with android x86 kernel, compared the changes and created patches to apply on 3.16.

Also used experimental kernel 3.14 released from AOSP to ensure which changes were related to Android.

Some extra changes were required in order to compile and run it (listed some of then in the end of this post)

In the systems I tested (AMD A10 5800K / Celeron E3300 with Nvidia GT630) most of basic functions worked (watching videos, surfing at Web, etc). 

Nouveau performs a bit better with this kernel than the previous one (3.10.x), due the driver changes inside kernel. I noted a big difference playing videos.

Currently, wifi network is not working (unable to store keys /authenticate - appears to be related to wpa-supplicant). Haven't tested with open networks.

Wired network is working.

********************************************************************

WARNING: If you want to give a try on it, keep in mind that:

 - These changes may contain bugs that can DAMAGE your hardware and cause DATA LOSS.

 - Some hacks were made to bypass some security. So this may EXPOSE your machine and network.

Use it AT YOUR OWN RISK. YOU WERE ADVISED

********************************************************************

If you want to build your system with these changes, here's 2 alternatives

1) Applying patches:

1.1) Download kernel 3.16 source (from kernel.org) and unpack it 

1.2) Copy the attached patches to the download kernel directory

1.3) Apply them with "patch -p0 < patch_file_name". Each patch will modify files from the correspondent directory (kernel, arch, drivers, etc)

1.4) Copy Android.mk file from Android-x86 kernel dir (ANDROID_SRC/kernel) to your downloaded kernel directory

1.5) Replace current Android-x86 kernel directory (ANDROID_SRC/kernel) by your patched 3.16

1.6) Clean previous build and start compilation

2) Ready modded kernel

2.1) Download modded kernel source from here:

https://drive.google.com/file/d/0BxO6THtB865fNFFRYzdCbDM2X3M/edit?usp=sharing

2.2) replace your existing kernel dir (ANDROID_SRC/kernel), clean up previous build and kick in.

* * * 

There is an ISO I built to test on my hardware. It's using mesa 10.1.5 and is intended for Radeon (non CGN) and Nvidia GPUs (This won't work for Intel GPU users)

https://drive.google.com/file/d/0BxO6THtB865fZXM0bER4TUdvUlk/edit?usp=sharing

* * * 

Some of the "ugly" hacks made:

 - net/ipv4/tcp.c: Commented reference to rcv_saddr on ipv6 code

      /*s6 = &inet->pinet6->rcv_saddr;

      if (ipv6_addr_type(s6) == IPV6_ADDR_MAPPED)

      continue;*/

 - drivers/input/evdev.c: Removed call to wake_lock_destroy

/*if (client->use_wake_lock)

 wake_lock_destroy(&client->wake_lock);*/

- Disabled NETFILTER_XT_MATCH_QTAGUID parameter on kernel config to avoid errors related to xt_qtaguid.c

- drivers/gpu/drm/drm_drv.c: ignored return from drm_ioctl_permit (permition check for drm ioctl, based on extra permissions, like CAP_SYS_ADMIN/DRM_AUTH

I attached a file with some personal notes: "estudos_loucos_kernel_android_20140809.txt" (In Portuguese)

Have fun.

Did you download the existing patched kernel or did you manually patch yourself?

did you add it as dual-boot with windows 8.1???

does it use uEFI or BIOS????

[Сергей Трофимов]

Yes, its dualboot with Windows 8.1.
On Onda V975w install 32-bit UEFI BIOS.
On the tablet was able to run and install:

the kernel is here in this thread, we provided the patches to Pstglia's original 3.16.0 kernel to upgrade
it to 3.16.1, which he used as I recall to update his kernel...which is available from his github pointer listed here also...

we do have some backups here which I'll check over the upcoming thanksgiving holiday......

there was one thing I do recall though.....the Boardconfig.mk had a driver that was provided by someone

and was incorporated.....in kernel 3.16.1 it was "out of staging or where ever we got it from" and part of the regular
kernel 3.16.1, so we had to disabled it in Boardconfig.mk and enabled it in kernel defconfig for a correct build....

the defconfig we used was always from the provided kernel supplied by an android-x86 sync....with any changes like

the one referred to above and others mentioned by testers in this forum..........(multitouch/ntrig etc.)

Hello again,

 

I found the problem.
Driver version 3.16.0-android-x86.
But Android x86 5.0 is 3.16.1-android-x86 - https://groups.google.com/d/msg/android-x86/qzU0G2zz8xE/-leOh9zw5ZYJ

You're right. Not only kernel version. There's also the magic numbers/symbols (modprobe --dump-modversions goodix.ko).

I've created an iso building with this goodix touchscreen driver incorporated (Kitkat 4.4, kernel 3.16.1, Mesa 9.20 with intel classic drivers enabled). If you want to give a try:

https://drive.google.com/file/d/0BxO6THtB865faFU1Yno1NzJudFE/view?usp=sharing

Note: The kernel module is on system/lib/modules/3.16.1-android-x86+/kernel/drivers/net/wireless. This is because I replaced an old and unused driver (I hope!) by the goodix driver as this is just a test. 

You have to load it manually the same way you tried before

Regards,

pstglia

[Сергей Трофимов]

Hello.
Thanks for the help.
Unfortunately touchscreen does not work, although it is present in the lsmod.
goodix 3011 0 - Live 0x00000000
In the folder /dev/input new events does not appear.
ls /dev/input
event0 - keyboard
event1 - mouse
event2 - ?
event3 - ?
event4 - ?
mice - mouse
mouse0 - mouse

Please send me the source code of the kernel with patches and Intel drivers installed on the my email (fim...@gmail.com). Or place them on file sharing.
Source code drivers are constantly updated. I would not be comfortable every time ask them to compile. If I have the kernel sources, I can compile the driver himself.
Sorry for my bad english.

All the sources are on github

https://github.com/pstglia/linux

One of the branches is kernel 3.16.1

Many drivers are already enabled on this (basically the same as 3.10, as I got them with a make oldconfig)

You can enable/disable mesa/drm drivers on BoardConfig.mk

These requires Mesa + llvm changes to be able to compile on Android-x86. Probably some gralloc changes are also required.

[pstglia]

Unfortunately no.  Unless Nvidia changes it or release source code for community. 

Our only hope is nouveau...

[Joan R. Serra]

is it not possible to add to kernel a package from NVidia ? The same as we do in Ubuntu, or to add the module with Nvidia drivers to kernel?

Thanks

nvm, I got this working.

For people who have rtl8723au as wifi driver and it doesn't work, do those changes:

1:

Folder:
~/kernel/arch/x86/configs
File:
android-x86_defconfig

Line 4968:
Change "# CONFIG_R8723AU is not set" to "CONFIG_R8723AU=m"

2:

Folder:
~/device/generic/common
File:
BoardConfig.mk
Line 28:
Erase 8723au from TARGET_EXTRA_KERNEL_MODULES.

 

Notice that this will only work on this kernel 3.16.

[Greg McGee]

the goodix touchscreen and the rtl8723au are (iirc) used on the Microcenter Winbook tablets, which seem to be nice hardware otherwise.

The wifi and BT are on the same chip, are both working yet?

The Winbooks do have a full size USB3 port, so adding a dongle if you really need BT should be possible.

[André Vitor]

Only WIFI is working for now.

[Austen Huffman]

I know it might be a stupid question, but how would I go along to get the MicroCenter Winbook TW801 working correctly. The WiFI (Realtek RTL8723BS Wireless LAN 802.11n SDIO Network Adapter) won't work along with Bluetooth (I don't know, Windows Device Manager has no info.) The Goodix Touchscreenworks fine in the Android 4.4 rc2 EFI Image.

Hi pstglia,
I'm an android newbie. I have a question about porting custom kernel to android x86. If I want to use your kernel 3.16 with android lollipop 5.1.1, What do I do? Can you get some guides for me, pls?

Hi,

Thanks and Brg!

Basically, you have to:

1) Replace kernel directory by the kernel source you want to compile

2) Include Android makefiles on it (kernel/Android.mk, in this case)

3) Create a Android kernel config for your target. To do this, I basically run on root source directory (assuming your target is lollipop with 64 bits build):

. build/envsetup.sh
lunch lollipop-x86-eng
make -C kernel O=$OUT/obj/kernel ARCH=x86_64 oldconfig

4) After running the cmds above, I copy $OUT/obj/kernel/.config to kernel/arch/x86/configs/android-x86_64_defconfig

5) At least, this patch is mandatory to enable booting your kernel (HACK: drm: disable GPU authentication):
https://sourceforge.net/p/android-x86/kernel/ci/6daa9a6a4b9727ed2f3567199130f336e8bd810a/

Maybe some more details are required, but basically that's it from what I recall

Use this to have more details:

[thangnn]

Thanks pstglia,
I replaced android x86 lollipop kernel (4.0.9) by your kernel (v3.16_android) as your guides and compiled complete.
But I can't boot it. I can use debug mode, only console not graphic. I think that it has problem with graphic. But I can not get log msg. I'm using stb intel Atom(TM) CPU  Z3735F, baytrail audio.
With android x86 lollipop kernel (4.0.9), get from http://www.android-x86.org, I can boot complete. But, drivers is good with kernel 3.10 - 3.16. So I want to downgrade the kernel.

Thanks & Best regards!

From the time we prepared this kernel version, we were using different libdrm and mesa versions. Maybe the newer versions are incompatible with this old kernel version. If that's the case, you should downgrade mesa and libdrm too.

Take a look at dmesg / logcat

By the way: What is your hardware you have and specifically which drivers works better with 3.16 than current version?

 

[thangnn]

Should I downgrade mesa and libdrm to android-x86 4.4.4?I will try it.
If I boot normal, I can not get logcat/dmesg. Because of it always reboot after detecting android x86 and found dev/sda1...
Audio driver works better with 3.16 than 4.0.9. With version 4.0.9, I can't find audio device (baytrail audio for hdmi & jack 3.5). And every patch files for kernel 3.10-3.16.

Just replace external/mesa and external/libdrm from an older version (preferable matching the version used on 3.16)

 AMCR0F28 is the acpi id for intel machine driver. Codec / Dsp should be Realtek or max device.

cat /proc/asound/cards can show you more info

from previous msgs, I replaced external/mesa and external/libdrm by
android 4.4_r3. But it has the same error. I'm continuous checking it.
I cat /proc/asound/cards but I don't see AMCR0F28 and HAD0F28. So I can

Oh NO, My target is 64 bits. But I think that it supports 32 bits too.
