Installing FreeBSD on fancy HP Cluster server boot error: (noperiph:sym0:0:-1:-1):SCSI BUS reset delivered.

Greetings

I'm trying to install FreeBSD on a HP Cluster Server. But when I boot with the 
CD's ( 4.4, 4.8 & 5.0 ), it will boot all the way upto "Wait 15 seconds for 
SCSI devices to settle" and then it immedialty give the following message:

(noperiph:sym0:0:-1:-1):SCSI BUS reset delivered.
(noperiph:sym1:0:-1:-1):SCSI BUS reset delivered.

After this the machine is basically unresponsive/dead. 

Any idea what could be causing this and what I could do to fix it ?
