I'm seeing the same problem on my MSI P35 Neo3 board. I don't have any drives connected to the SATA ports of the controller, unfortunately I need it for my PATA DVD drive.
Disabling the JMicron controller from the BIOS stops these messages from appearing. So the guilty piece of hardware seems to be 03:00.0 SATA controller: JMicron Technologies, Inc. JMicron 20360/20363 AHCI Controller (rev 03) 03:00.1 IDE interface: JMicron Technologies, Inc.
