Hi Keir,

No, the ia64 Windows does not generate the crashdump by the NMI. 
In the ia64 machine, the NMI interruption and the INIT interruption 
are generated by different mechanism. 
I don't adhere to the name of 'send_init'. Rather I think that 
'trigger_dump_switch' which you named it is better. 

Best regards,
 Kan
