Can you post your dmesg from bootup with the controller/drive detection?
So you've got 6 drives in the machine. Intel chipsets normally seem pretty 
robust with AHCI.

Are you certain that your machine has enough power to run all those drives 
properly? We've seen in a number of cases that power fluctuations or noise 
can cause these kinds of errors.
I have a 650watt PSU (nice antec one) and the power draw of the box is 
~148watts w/ veliciraptors, ~250 when fully load all 4 cores + all 12 
disks writing.  I have turned off the irqbalance daemon and I am going to 
see if the problem re-occurs.
