   \item PREEMPT\_RT is delivered as a patch against the mainline
     kernel
     \begin{itemize}
-    \item Best to have a board supported by the mainline kernel,
-      otherwise the PREEMPT\_RT patch may not apply and may require
-      some adaptations
-    \item Similarly, only long term stable releases of the kernel
-      are supported, currently: 5.9, 5.4, 4.19, 4.14, 4.9, 4.4.
