+@strong{WARNING: The SMP support in RTEMS 4.11 is highly experimental and
+incomplete. Due to the use of the Giant lock and other implementation
+shortcomings it is unsuitable for systems that need a predictable timing
+behaviour. Some issues are already fixed in the development version of RTEMS
+4.12. There are no plans to fix them in RTEMS 4.11. Before you start using
+this RTEMS version for SMP ask on the RTEMS mailing list. The SMP support in
+4.11 is good enough for simple demonstration purposes. It is work in progress
+and a future version of RTEMS will provide proper SMP support.}
