I installed Ubuntu server 12.04 to my new server and it failed on the first boot. It just stopped and I can't proceed any further.

Server's specifications:

Dell PowerEdge T620
CPU : Xeon E5-2665 2.4G x 2
RAM : 8GB RDIMM, 1333MHz x 12
HDD : 3TB Near Line SAS 7.2K x 8
RAID controller : PERC H710
GPU : NVIDIA Tesla C2075 x 4

I have a screenshot of the screen it stopped on but I cannot attach it because my privilege level is currently too low.

![freeze on boot][1]

Here are the last messages while booting.
