and you are sure that this problems are caused by the RT patch or is
there a chance that this is unrelated to the RT patch?

It is stable and I am not aware of any ARM / IMX specific problems.

Since this got here from kernelnewbies: I would not recommend the
Preempt-RT patch set to add to any kernel just to have fancy patches.
People use it because they need to fulfill specific requirements which
would not work without it. You might want to check some of the
