  Okay.  So, in looking at the diffs from netbsd-4 to netbsd-5  
sparc64/dev/psycho.c, I see that the API to intr_establish changed.   
But, I was surprised to find that intr_establish() (within  
psycho_set_intr()) returns successfully on this last call that never  
returns.

  The *last* line of psycho_set_intr() does not complete.  What could/ 
would make this hang?

        *(ih->ih_map) |= INTMAP_V|(CPU_UPAID << INTMAP_TID_SHIFT);

  I littered printf()'s through psycho_set_intr(), and the set of  
calls from psycho_attach() yield ('**' in psycho_attach, '@@' in  
psycho_set_intr()):

  At which point it hangs.  The last '@@' printf is after the call to  
intr_establish in psycho_set_intr, and the "returning from" printf  
that never fires on that last pass is after the line of code pasted  
above, and immediately before the close brace (and return).

  I think I'm out of ideas, right here.  Anyone else have any notion  
what's gotten messed up?
