[PATCH 2.6.18-rc3,] ieee1394: sbp2: enable auto spin-up forMaxtor disks

From: Stefan Richter
Date: Wed Aug 02 2006 - 13:41:35 EST

At least Maxtor OneTouch III require a "start stop unit" command after
auto spin-down before the next access can proceed. This patch activates
the responsible code in scsi_mod for all Maxtor SBP-2 disks.

Maybe that should be done for all SBP-2 disks, but better be cautious.

This patch is also available from the ieee1394 git tree:

Fixes loss of connection if an external Maxtor disk automatically went
into power saving mode.

Enthusiasts may pick up a variant of this patch for 2.6.16.y at
