MagicAndre, excellent tutorial. However, when I got the table, the module that was eating up all my CPU was "Unknown", and the function was "0xfffffa80076e15a0". This was in the Interrupt CPU Usage Table. In the DCP CPU Usage table, the big boy was a very similar process; Module "Unknown", and function "0xfffffa80076e10a0". Do you have any insight? I would attach the ELT, but it's 54 megs...
