Sounds awfully similar to the recent nvidia data corruption issue. It

off by passing "iommu=off" as kernel parameter.

Blast. I stand corrected - it didn't fix it.
I now have 3 300G drives hanging off the add-in card, sda sdb sdc. I did
the following:
# Make a RAID5 array of 3 out of the 4 drives I'll eventually be using
mdadm --create /dev/md6 --chunk=64 --level=raid5 --raid-devices=4
/dev/sda1 /dev/sdb1 /dev/sdc1 missing
Here's an odd data point.
I just broke that array, formatted all three of those partitions seperately,
mounted and did my ISO copy test.
All three drives, run one at a time, function fine. No corruption.
