Is it possible that this problem is also exhibited by a 4.9-STABLE 
Kernel from January 22nd?  i.e. might this same (or a similar) problem 
have existed in the previous driver?

I am seeing i/o hangs (swap_pager: indefinite wait buffer messages) on 
one of our boxes here.  (4 x Maxtor 300GB drives / 3ware 7506-4 / 2.4GHz 
Xeon Dell 1600SC).

The machine is a backup server running BackupPC - it does experience 
heavy load and i/o stress.
