Thanks for pointing that out. I have indeed noticed such reports but I didn't 
see any specific plans or ack's to take these issues from mpt. Thus the 
question is if these reports justify the assumption that there was anything 
wrong with mpt in general.

I didn't want to make the point of denying some of mpt's core features. I just 
saw a couple of reports that involved SAS Expanders, specifically those based 
on LSI silicon, reported under the "mpt problem" umbrella, and I understood 
that these issues were quite obstinate.

Excellent. That's encouraging. I am planning a similar configuration, with WD 
RE3 1 TB disks though.
