Well, took everything apart today and put it all back together--we'll see what happens.
Has anybody ever seen what I've described with the NumLock light? Basically, when it's locked up, the NumLock light will light up when any key is pressed, and then go back off when everything is released. It would seem to me that the kernel would still have to be alive and kicking in that case--any way to make it spit out a core dump when that happens? Thanks again!
