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.
