Kernel Backport for Debian Jessie?
 
I installed the 32 bit version of Debian Jessie (8.0) on an Asus X205TA. The Asus X205TA laptop is quirky like a lot of Intel Baytrail Atom laptops/tablets in that it has 32 bit EFI but a 64 bit capable CPU, and installing Linux on them is an exercise in frustration. Jessie is probably the first distro to support 32bit EFI out of the box, and the install went surprisingly smoothly. As expected the sound and built in WIFI does not work, but everything else seems to work well.

I spent half a day compiling the 4.03 kernel but it crashes on boot, and I ended uninstalling it in frustration.

Is there any backport of the 4.0 (or 4.1 which is currently a release candidate) for Jessie? Debian also seems to have pulled the kernel image off of their "experimental" repository.

Thanks.

In addition to the answers supplied over at forums.debian.net -- I am using the Liquorix kernel in my BunsenLabs system (modified Debian jessie) right now and it seems to work very well.
Code:
empty@BunsenLabs ~ % uname -a
Linux BunsenLabs 4.0-2.dmz.2-liquorix-amd64 #1 ZEN SMP PREEMPT Debian 4.0-7 (2015-05-12) x86_64 GNU/Linux

Did you copy oldconfig?

@haziz , just add debian unstable (and backports) to your /etc/sources (something similar to: )

Code:
[...]
#jessie-backports
deb http://ftp.us.debian.org/debian/ jessie-backports main contrib non-free
deb-src http://ftp.us.debian.org/debian/ jessie-backports main contrib non-free

#Sid unstable
deb http://ftp.us.debian.org/debian/ unstable main contrib non-free
deb-src http://ftp.us.debian.org/debian/ unstable main contrib non-free
[...]
and pin stable as default in /etc/apt/preferences (something similar to: )
Code:
Package: *
Pin: release a=stable
Pin-Priority: 700

Package: *
Pin: release a=jessie-backports
Pin-Priority: 660

Package: *
Pin: release a=unstable
Pin-Priority: 90

then to install kernel 4.0 from debian unstable, do
Code:
sudo apt-get -t unstable install linux-image linux-headers

I'm confused -- why did you install a 32 bit OS on a 64 bit machine? I'll admit it may not make an extreme difference but it ought to be better to use an OS compiled to use your CPU and not a processor from a decade or two ago.
