Hi all,
I am somewhat at a loss for how to debug this problem.
Basically my system locks up, its a workstation grade Xeon I do
development on, essentially, the screen (in X) freezes, the keyboard
locks, the network locks (it stops responding to ping). The only
visible indicator I get when it freezes is sometimes, I see a 4 or 5
pixel high band of grey/brown that spans the width of the window I am
currently working in.
I dont see anything out of the ordinary that something is wrong, I can
let the system sit for days and it runs fine, but when I start doing
work on it, I start seeing the freezes (it froze up twice in about 3
hours today). But sometimes I can work several days in a row without a
problem.
This sounds like it might be a hardware problem.
I would like any ideas on how to debug this.
First suggestion: run MEMTEST for a few days without interruptions.
No, wait, my Zeroth suggestion: Check that your fans are running
and that the CPU temp is not out of spec.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
