Here's something interesting though, I just tried writing to the one disk on

from it and write to it. So something to do with mdraid, or the XFS filesystem
(or both) is causing a bad interaction with the card itself.

Try doing IO to multiple drives simultaneously. I had a SIL card that would corrupt data when used in RAID, but not single drive IO tests. I could make it fail by doing multiple dd/cp/md5sum to two drives simultaneously.

Do yourself a favour. Whack it on fleabay and sell it to a Windows user, then get something supported. Leave enough scatter around that people thinking of buying a card with that Marvell chipset will stay clear.
