Decoding mptscsih errors

Tue Oct 10 18:44:47 CDT 2006

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
