FWIW, I had 3 identical 2450s similar to
yours, all with RH linux 7.2 installed -
2 of them were rock solid, the other had
random crashes, nothing in the logs, no
pattern to the crashes that I could see.
Dell had me upgrade/reflash the BIOS
and the perc raid controller, and the box
has been rock solid ever since...
Just my $.02 on the matter -
