[Xenomai-help] kernel screen dump: "scheduling while atomic: "

Hi,
 
I have a user space real-time application that uses fusion/xenomai 0.9.1
native API on linux kernel 2.6.11 and uClibc-0.9.28.
Everything seems to work fine, but after the application has run for some
time (10 to 20 minutes), the following screen dumps begin to appear on the
console:
 
     scheduling while atomic: <my_real-time_func_name>/0x00000002/276
 
followed by a call stack dump.
My application continues to run normally, the scheduling of my real time
func seems ok too, but I wonder,
why this screen dump appears and can in be disabled?
 
Thanks,
Georgi Stoykov

Which architecture are you running on?

It's the sign of a bug, either in your application, in Xenomai, or maybe in the 
kernel itself. Please send the complete stack dump so that we can figure out 
what's happening.
