Hi Dorian, hi Yanzhen,
in Ubuntu 12.04 the RT-Preempt kernels from official Debian wheezy
repository can be used. The 3.2-rt kernel from debian wheezy works
without any additional changes. The 3.14-0.bpo.2-rt kernel from debian
wheezy-backports requires udev packages to be installed from
wheezy-backports repository. Otherwise the system will not boot.
In Ubuntu 14.04, the 3.14 RT-Preempt kernel from Debian jessie can be used.
Best regards,
Jürgen
