I'm also experiencing the same issue..

These messages have been coming in from time to time (sometimes a couple per day).  I've tried getting around with this with various kernel settings such as noapic with no luck.

The drives are running on a Supermicro 8 port SATA card (AOC-SAT2-MV8) that's plugged into a standard PCI slot (not pci-x).
