Here is the patch:



From: Tomas Henzl <thenzl@...hat.com>

A lot of 64bit machines with Adaptec 2200S and 2120S controllers don't
recognize SCSI disks any more with the patch "fix driver failure with Dell
PowerEdge Expandable RAID Controller 3/Di", but fail with tons of "aac_srb:
aac_fib_send failed with status: 8195" instead. This patch disables the
quirk introduced in the change cited above for those two controllers again.
