Subject: [PATCH 05/16] qla2xxx: Do not take a second firmware dump when intentionally generating one.
Date: Tue, 25 Jun 2013 11:27:20 -0400 [thread overview]
Message-ID: <1372174051-4211-6-git-send-email-saurav.kashyap@qlogic.com> (raw)
In-Reply-To: <1372174051-4211-1-git-send-email-saurav.kashyap@qlogic.com>
From: Chad Dupuis <chad.dupuis@qlogic.com>
When we are intentionally generating a firmware dump by executing the
MBC_GEN_SYSTEM_ERROR command, the command actually times out. The normal
course of action when a mailbox command times out is to take a firmware dump.
However, in this special case we do not want to do this since the
MBA_SYSTEM_ERR AEN already generates a firmware dump.
