can a rate monotonic task be interrupted?

Yes.  By default all RTEMS Classic API tasks (created via
rtems_task_create)
are preemptible by both higher priority tasks and interrupts.  This
is directly compatible with hte rate monotonic scheduling theory.  You
could easily violate this assumption by turning off interrupts or making
the task non-preemptible though.

All that the rate monotonic manager in RTEMS does is provide a nice
mechanism for periodic tasks which don't drift.
