Stack trace is always different.Can you check that the power supply is sufficient for all these disks?Do you have recommendations ? I haven't found so much information on how to estimate the power need. Currently this is a 600W power supply (FWIW: Cooler Master Silent Pro M - 600W)Many motherboards have a voltage monitoring chip, which you should be able to read with the 'sensors' command from the 'lm-sensors' package. This should show whether the actual voltages are being pulled down because the power supply is overloaded. You would need to actually make all the hard drives active while checking this.

cpu0_vid: +0.513 VAssuming the sensors.conf is OK (which is not 100% sure for that Gigabyte GA-890GPA-UD3H mobo, AFAIK), do you think the 4.92V for the 5V is too low ?
I was hdparm'ing some disks while, compiling a kernel and a raid5 sync was inprogress at that time (and it freezed, of course)
