[CentOS] Kernel Panic at Boot

Hi All,

This is a Centos 6.4 system used as a home server and Myth backend 
machine. It has just suffered a motherboard failure and I have got a 
identical replacement.

This machine normally runs in run level 3. It has a NVidia graphics card 
and the NVidia driver installed but I found it crashed the machine as 
soon as I started X on there. So I never bothered with X and left it in RL3.

So as part of the re-commissioning of this machine I decided to remove 
the NVidia driver and go back to Nouveau. I shouldn't have bothered.

Even starting in RL1 it kernel panics at bootup toward the end of the 
boot process. If I boot it in level 3 all the daemons start and it runs 
a little bit of script I have in rc.local to enable ACL's and then panics.

The panic is something like

panic occurred, switching back to text console.
general protection fault: 0000 [#2] SMP
last sysfs file: /sys/devices/virtual/block/dm-5/dm/name
Modules linked in: "........list of modules......."

There's a list of CPU registers and a call trace after that. I have a 
photo of the screen if that information is useful

Any idea how I can trace this.

Many thanks
