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.
