I'm experiencing the same issue with a brand new install, though
different hardware ... I've an Adaptec 1205 SATA controller and a pair
of Samsung 160 gig drives.

Error only occurs under load, the first time it happened the machine
locked and spontaneously rebooted and required a manual fsck of the
mirror; which completed successfully, but then rebuilt the mirror very
slowly ...

Second time, the stressor (copying a 5 gig drive image to it) the
machine held up, but got many DMA WRITE errors to ad6 ... below is the
smartctl output on that drive, but I don't see anything other than the
DMA WRITE errors, though I confess to not being really up on what
smartctl outputs ... 

lighty# ./smartctl -a /dev/ad6
