I've noticed problems with this card too, running amd64 on a AthlonX2.

I've got a ZFS pool setup, and when scrubbing the pool it comes up with 
erratic CKSUM errors (for example, scrub once and get 7 errors, scrub 
again immediately and get 53 more).

Previously I had these drives (Seagate Barracuda ES ST3320620NS) plugged 
into the motherboard SATA ports of the same machine, (nVidia nForce 
MCP51 SATA300 controller) with no issues at all.
