rtems_task_resume within ISR

I want an ISR to activate an error handler process on certain faults. I
assumed that the following simple code would activate the error handler
(which is the process with the highest priority, but normally suspended)
AFTER the completion of the ISR:

rtems_isr fault(rtems_vector_number vector) {
    rtems_task_resume(eh_id); // eh_id is the error handler
    /* do some other stuff */

But it seems that the error handler (eh_id) becomes immediately ready
and starts execution BEFORE the ISR termates. Is there anything wrong
with my code?
