To be explicit FreeBSD 10.0-RELEASE would be uneffected by the corruption
bugs we fixed, however there has been at least one fix / enhancement that I'm
aware of since 10's release for later cards.

The key thing to determine here are precise factors of the corruption your
seeing as it looks like there is some mixing up of issues

Given this could you confirm:-
1. Hardware
1.1. LSI card / generation
1.2. Disks
1.3. Hotswap adapter / expander
2. Firmware
3. OS Version / driver version
