From 00701a96f81f4e1b7279f5e05fe02274bbe29e59 Mon Sep 17 00:00:00 2001 From: Justin Lindley Date: Thu, 29 May 2014 10:52:47 -0500 Subject: [PATCH] hpsa: change doorbell reset delay to ten seconds After 3.22 firmware, PMC firmware guys tell us the previous 5 second delay after a reset now needs to be 10 secs to avoid a PCIe error due to the driver looking at the controller too soon after the reset.
