I had the same problem on a work station running ASCII. Since I could
access the system from another machine on the LAN and even log in, I
guessed that it was Xorg. Killing X Via a remote login cleared the
problem. With the use of sar and other tools, I determined it was the
video card and/or NVIDIA's drivers (kernel modules). Switched back to
the system board's video (AMD) and the problem went away.

Hope this helps.
