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.
