From edbabd8679a39faef67def4438c9cbccb5c05c5d Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sun, 2 Apr 2006 20:55:02 +0900 Subject: [PATCH] [PATCH] libata: add 5s sleep between resets Some devices react badly if resets are performed back-to-back. Give devices some time to breath and tell user that we're taking a nap.
