[ltp] XFree86 locking and crashing on T40 with RedHat 9.0

[Neil Weisenfeld]

Several people (myself included) have had random X crashes attributed to
bad memory shipped with their T40's.  I'd suggest running memtest86 from
www.memtest86.com just to be sure.  I was going crazy with kernel
compile crashes, X crashes, the clock applet crashing, etc., etc.  A
replacement memory module from IBM did the trick.

This was not a transient problem in that I never had Memtest86 make it
through a pass without a lot of errors cropping up somewhere in the mix
and related to the second 512MB module.  If memtest comes up clean, then
you should look elsewhere.  Certainly make sure that you have the latest
errata kernel from RedHat.  What shipped originally w/ 9.0 was not
ideal.
