Problem with udev upgrading from wheezy to jessie

[Martin Hanson <greencoppermine@yandex.com>]

I am trying to upgrade a cubox (arm) from Wheezy to Jessie, but I keep running into problems with udev. When I try to install latest kernel from backports:

<SNIP>
# dpkg -i linux-image-4.3.0-0.bpo.1-armmp_4.3.3-7~bpo8+1_armhf.deb
dpkg: regarding .../linux-image-4.3.0-0.bpo.1-armmp_4.3.3-7~bpo8+1_armhf.deb containing linux-image-4.3.0-0.bpo.1-armmp:
 linux-image-4.3.0-0.bpo.1-armmp breaks udev (<< 208-8~)
  udev (version 175-7.2) is present and installed.

dpkg: error processing archive linux-image-4.3.0-0.bpo.1-armmp_4.3.3-7~bpo8+1_armhf.deb (--install):
 installing linux-image-4.3.0-0.bpo.1-armmp would break udev, and
 deconfiguration is not permitted (--auto-deconfigure might help)
Errors were encountered while processing:
 linux-image-4.3.0-0.bpo.1-armmp_4.3.3-7~bpo8+1_armhf.deb
</SNIP>

Then trying to solve that installing udev:

<SNIP>
# dpkg -i udev_215-17+deb8u3_armhf.deb 
(Reading database ... 50189 files and directories currently installed.)
Preparing to unpack udev_215-17+deb8u3_armhf.deb ...
Since release 198, udev requires support for the following features in
the running kernel:

- inotify(2)            (CONFIG_INOTIFY_USER)
- signalfd(2)           (CONFIG_SIGNALFD)
- accept4(2)
- open_by_handle_at(2)  (CONFIG_FHANDLE)
- timerfd_create(2)     (CONFIG_TIMERFD)
- epoll_create(2)       (CONFIG_EPOLL)

Please upgrade your kernel before or while upgrading udev.

AT YOUR OWN RISK, you can force the installation of this version of udev
WHICH DOES NOT WORK WITH YOUR RUNNING KERNEL AND WILL BREAK YOUR SYSTEM
AT THE NEXT REBOOT by creating the /etc/udev/kernel-upgrade file.
There is always a safer way to upgrade, do not try this unless you
understand what you are doing!

How do I solve that, one is depending upon the other, but the other won't install as long as the first is running.
