Unable to handle kernel paging request at kthread_should_stop

Hello,

In a kernel module which used to work on previous kernel versions I tried to
start a kernel thread (kthread). In the threads mainloop I poll the method
kthread_should_stop which seems to fail.

My platform is an Intel Atom CPU N270.
# uname -a
Linux systemmanager 2.6.33.2-rt13 #1 SMP Sat Apr 10 00:12:20 CEST 2010 i686

I attached a test module to reproduce this bug.  Does I miss something in my
code or is there a bug?

Thanks for any help
