So there isn't a kernel panic or anything else associated with this
problem?

When the system locks up, its just that...a complete, hard lockup. No
errors, no clues left behind. If NUMLOCK was on, it stays
lit.....keyboard has no effect anymore....only poweroff is the solution
(hold 5secs or so).
One time i was running Memtest Dell utility, and it got to some
percentage on one of the tests, and simply locked up. Everything remains
on screen...and the counters ofcourse stop.
Its very random, it occurs when system is busy or when completely idle.
Mmmhhh....so that is the backplane.

_thanks
