I'm not sure if one can gdb kernel code, but see my previous email: the
preempt-rt kernel runs the real-time stuff all in user space. That's
why we don't get the /proc debugging stuff you're used to with RTAI, and
why we can use gdb. The downside is that an optimistic latency value is
30ms compared to, I seem to remember, <10ms for RTAI or RT-Linux (you
folks will know that better than me).
