strange problem(s) - hardware related?

	Hello list,

	I made my first LFS almost two years ago. Since then, I made many LFS
builds on various hardware. I never had any unsolvable problem, at least
not solvable by help of LFS-news archives :) But, my last build is
choking, and I am out of luck, debugging it. I tried many "solutions"
without success. Including but not limiting to kernel changes, gcc
changes, new build, CFLAGS bashing, hardware changes ... you name it.
The problem is as follows: box runs fine on itself, idles for days
without any problems, but, when I do some IDE intensive job, *WITH*
compiling (kernel-tree would do, mozilla, or anything big), it locks up
solid, after 2-5 minutes. No SSH, no serial login, nothing. Logs are
empty, also. Just plain lockup. I suspected hardware, as I earn my bread
in software industry, and hardware is always firs suspect :) You guessed
it, it didn't work. I changed MB (same model), CPU (same model), Video
(Nvidia vs ATI vs Matrox), no luck. As I isolated all possible causes of
malfunction down to CPU and MB, my strong guess here is that chipset is
doing havoc. Easiest way to solve this one is to go for another
chipset/MB. But I wont do it. What makes me angry here is that M$ new
toy XP, works in this configuration for weeks without any glich. That is
so frustrating. What I want to do is debug this thingie. Any insides or
similiar problems would be appriciated. I paste my significant /proc
entries along with this post.

	Thank you for your time guys (and gals?) :)

BTW.	Last config (read -> this one) I ran, includes nmi_watchdog=2 and
lockups are not often as before.
