Yes, that message seems to show up no matter what with the 2.6.20  
kernel with RT stuff.  The code snippet in sched.c is:

1               reacquire_kernel_lock(current);
1               if (!irqs_disabled()) {
1                       static int once = 1;
1                       if (once) {
1                               once = 0;
1                               print_irqtrace_events(current);
1                               WARN_ON(1);
1                       }
1               }

right at the tail end of __schedule() -- the "1" prefix there shows  
that all those lines were added by the RT patch.
