Howdy all,

I've been running a Dell PowerEdge 6400 with a PERC Megaraid 2/DC on
CentOS 4.x for over a year now. I just rebuild the last stable megaraid
driver for it.  It runs with no problems; and this is on my main web
server with 150+ virtual hosts.  Bit of an annoyance, but not terrible.
I found the directions on the web via a search of CentOS 4.x rebuild
