Here, I assume you mean Xenomai branch v2.3.x revision 2299
> 2. Kernel 2.6.19.2, Xenomai r2299, Adeos 1.7-01
Here, I assume you mean Xenomai trunk revision 2299
The problem is that if there is no difference with regard to FPU context
management between release 2.3.0 and latest revision of branch
v2.3.x. So, the difference must be somewhere else.
Could you send me your .config ?
Also, is it possible for you to try bisecting in v2.3.x branch ? v2.3.0
release is revision 2004, and you know that revision 2299 does not work
for you, so you would be able to tell us exactly which revision is the
cause of your problem.
