Actually, That's a Host State Machine Violation. It results in a downed SATA link. Probably a quirk with the SATA controller hardware on the MOBO or a Linux driver not fully understanding how to talk to the SATA controller to work around the quirk. I'd suggest trying a different motherboard as we certainly can't be messing the drivers shipped with Centos. Steve WA6ZFT
