I am using a 32 bit Fedora 13, linux kernel 3.5.7 and xenomai-2.6.3.
Please do the followings:

1) insmod ./kerneltask2.ko
2) rmmod kerneltask2

The first time is OK. The second time the computer freezes and i have
a kernel panic and carsh dump every time.

Please post the panic somewhere.

You have to call rt_task_remove_hook in the module cleanup function.
Otherwise the hook remains registered with a module address no longer valid.
