the interrupt stack counter ci_intrdepth is initialized within locore.S 
and later again from the procedure cpu_attach_common. Is this correct?

On my system the external events refuse to work which lead to a crash 
since the decrementer is not refereshed. It works fine if it is only set 
within locore.S
