RedHat 7.2 install

[Carl Parrish]

Yeap I'm doing a *lot* of installs latly (pretty soon I'll be able to
say I can admin linux as well <wg>). Anyways now I've got a *new*
problem I'm trying to install RH 7.2 using the same disk I've always
used. the install seems to go okay however when I reboot it I get:
 "#Unable to handle kernal NULL pointer dereference at virtual address
########"

With different addresses. This is what I've tried so far. I swapped out
the memory and changed where on the board the memory was placed (long
story but before I had the memory in the 2nd socket moved it to the
first but don't really see any different so far). So now I'm thinking
maybe its not the memory. Maybe it *IS* the disk. Though like I said
I've installed on other boxes with these disks (I'm sure). So the
question is does anyone *know* what this is? Or how I should go about
fixing it?

Thanks, 
Carl P.
