From 289af13384c9acef62331918dc76840920c5816f Mon Sep 17 00:00:00 2001 From: Mikulas Patocka Date: Wed, 8 Jul 2015 13:06:12 -0400 Subject: libata: increase the timeout when setting transfer mode commit d531be2ca2f27cca5f041b6a140504999144a617 upstream. I have a ST4000DM000 disk. If Linux is booted while the disk is spun down, the command that sets transfer mode causes the disk to spin up. The spin-up takes longer than the default 5s timeout, so the command fails and timeout is reported. Fix this by increasing the timeout to 15s, which is enough for the disk to spin up.
