Hi Florian,
That's what I can't understand. The default Debian kernel 2.6.18 without
PREEMPT works fine.
Is it possible the PREEMPT option would bring to the surface faulty hardware
that non PREEMPT could handle?

I believe you mean 2.6.23-1-rt1. Good to know it does work.

So I can conclude it is most likely a hardware problem on my end.
