Hello again.
I have another problem and I'm not sure if it is connected with Xenomai ,
but perhaps you already met similar problem.
Occasionally  the math sin function takes an enormous amount of time
(400-450 us on Athlon A64 X2 4800+). When I detect this and make the sin function
call with the same parameter again, it takes the same (long) time. I
suspect that this function is for some values is unreasonably slow. I'll
try to capture some such values and post them here.
I don't remember such behavior before the transition to newer 64bit linux
distribution (Kubuntu 7.10 amd64 and kernel 2.6.24).
