Hello Matthias, do you still work with Kernel 3.12 and PREEMPT_RT ? The question is, how you built the Kernel, because I'm not shure how to inject the PREEMPT - Patch into Robert Nelson Kernel https://github.com/RobertCNelson/stable-kernel/tree/v3.1.x if it is Cross Compile on Ubuntu. Could it be done by the following lines: #cd bb-kernel
#patch -p1 <patch-3.12.24-rt37.patch <https://www.kernel.org/pub/linux/kernel/projects/rt/3.12/patch-3.12.24-rt37.patch.gz> #./tools/rebuild I'm not shure what happend because there is no PREEMPT option in the following configuration menue Thank you in advance Lupus Am Freitag, 17.
