| |
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. https://bugzilla.novell.com/show_bug.cgi?id=183011
Maybe that should be done for all SBP-2 disks, but better be cautious.
Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> --- This patch is also available from the ieee1394 git tree: http://www.kernel.org/git/?p=linux/kernel/git/bcollins/linux1394-2.6.git;a=commitdiff;h=31a379e1067834868b8f1ce3e409392c42dc0f2b
Fixes loss of connection if an external Maxtor disk automatically went into power saving mode.
