This should not be related with mptsas driver. We tested the same scenario with
lsi 36x expander and could not reproduce the same problem. It seems that the
problem is related to the original lsi 24x expander. Maybe the expander
firmware problem.

I think this is more likely to be a libata problem than a scsi problem?

I recategorised it that way, thanks.
