Scenario:
Xenomai 2.4.5, kernel 2.6.24-7 (x86)
I have success= fully trapped and restored int #0 (it is not reported in the example).
= =0ANow I want to trap fpu exceptions (#16) of a Xenomai user task (ring 3).=

xfpu_xcpt.c -> kernel module used to intercept and manage fpu (#= 16) exceptions.
xfpu_user.c -> xenomai user task

The easiest w= ay (it will not be so easy the final fpu exception manager of course!) to d= o this I knows was to do an fnclex but the example doesn't work (it hangs s= hortly).
I have tried *many* solutions but nothing works. I think the pr= oblem is I can't do a simple fnclex but I can't figure how to solve the pro= blem.

Thank you
