Just again. I do not try to explain, I report observations -:).

running on seperate CPUs but they're still running in kernel mode. A runaway device driver means you're toast. Now, a very very busy device, thats a seperate story. Having one CPU handle all of your disk/network IO and the second CPU handle all of your processes may alleviate some of the pain. May. There's more to it than just offloading stuff. If your processes are all _depending_ on IO to occur then you may end up with random crappy starvation situations. This has nothing to do with NANOG. Lets talk about DCEF bugs or something.
