If thats the mvsas driver, god help you. I had nothing but troubles with it 
for a good year or two or possibly more and it was never fixed or really 
acknowledged, so I sold that card (a supermicro aoc-saslp-mv8) and picked up a 
IBM m1015 (LSI 9211-8i a-like) and haven't looked back.

Basically it would reset a lot, and lock up. AND I believe it caused a lot of 
silent corruption as well.
