oversized DMA transfer attempt

I'm getting this error 609 times / second on 3.6.2 RELEASE.

ata1: FAILURE - oversized DMA transfer attempt 69632 > 65536
acd0: setting up DMA failed

> sudo grep DMA /var/log/messages | grep 03:00:30 | grep ata1 | wc -l

The error is contant and causing the HAMMER daemon to peg the CPU
intermittently. Any ideas on what might be going on?
