Could you also try if this patch changes anything:

(Could be the case if you happen to use some FPU-touching Linux driver.)
The patch would not apply to xenomai 2.2.4, so I checked out the svn
trunk (rev 1749), and then applied this patch. I get the same behavior.
I tried my mqtest2 example with a stock xenomai 2.2.4 UP kernel (instead of
SMP), and I still get the FPU error message and SIGXCPU signal. I also went
back to xenomai 2.2.1 SMP and still have the problem there.
Has anyone tried the example on some other hardware?
