Hi,
I asked one of our engineers about the HLT instruction and his explanation was
this..
The HLT instruction goes "live" when the machine sits idle, but it doesn't
halt your machines if you have "live" interrupts (like IRQ's, scheduling,
etc)..
If you have 0 interrupts - then it halts the machine down...
Hope this helps...
