Henri,

I read about your surface pro 3 problems. I had the exact same problems
with my tablet. wifi,bluetooth,touchscreen. There is also a bug in all
versions past 3.10 kernel you need to add the following to grub to fix the
random freeze/crash problem
intel - How to set intel_idle.max_cstate=1
<http://askubuntu.com/questions/749349/how-to-set-intel-idle-max-cstate-1>

I found linuxium has been ironing out all the bugs for the last year. Heres
the info :) Enjoy.

The kernel with all the cherry/bay trail patches is over on github
https://github.com/linuxium/ubuntu-zesty/tree/Ubuntu-4.9.0-11.12
For the zesty iso with the firmware fixed for the wifi/bluetooth and sound
problems

If I did not make it clear before your random crashes are because of a
problem that has been around awhile. It goes back to when intel only
created drivers/patches for the current mainline kernel. Anything after
3.10 needs the intel_idle.max_cstate=1 or it will randomly crash and burn
on a couple of generations of tablets. Linuxium patched that in his latest
4.9 kernel release btw.

OK. I'll try to build one with your patches but i can build just
marshmallow-x86, becouse my home network can't connect to osdn (no problem
with my mobile network).

freeze problem my tablet use this

First start kernel with: intel_idle.max_cstate=0

Then give these commands as root:

echo 1 > /sys/devices/system/cpu/intel_pstate/no_turbo
echo 1 > /sys/devices/system/cpu/cpu0/cpuidle/state3/disable
echo 1 > /sys/devices/system/cpu/cpu1/cpuidle/state3/disable
echo 1 > /sys/devices/system/cpu/cpu2/cpuidle/state3/disable

Does anyone have all the patches linuxium has used available somewhere?
Thank you for the zip youling 257.

I've tried to contact him for some days but haven't received a reply yet...
There are tons of commits in that repo and manually recreating those
patches from the commits, testing them, building and testing etc would take
a very long time! I haven't found out yet whether they'll be added to
mainline kernel someday either. I really hope so as it'd make the life of
most users much easier, especially for those who just wish to download,
install and run different distros.

Youling 257, for sure you are one of the most active and skilled members in
Atom baytrail tablet area in this forum, you helped me a lot with my Chuwi
tablets, now we have sound and BT but not perfect. You are continuosly
improving support for this kind of tablets. I'm a not programming skilled
user forced to find out how to complie kernels and using them with other
iso as a template. Most of us need/want a working iso for our tablets OOTB
but it seems not possible by now. Instead probably a lot of users of this
group would thank you a lot if you could open a thread with a complete
howto describing the customizing process to build a working kernel for our
tablets.
I know this is a hard work, and probably asking for this is a bit...., I
don't know how to name it in english sorry, probably all of you know what I
mean, but it would be a great support for this community. I would like to
contribute if someone so skilled as you can start this valuable thread.
Anyway if this is not possible, I'd like to thank you your hard work and
support in this group, again.

If you can't make an iso can you at least create a zip that we can load to a USB drive and load android with the patches?

I have a z3735f and have been trying to stop the freezing, getting the sound and Bluetooth working....
