From d33609607c5abc0b4b31d238e33f3ab075e2f96f Mon Sep 17 00:00:00 2001 From: Giridhar Malavali Date: Thu, 9 Feb 2012 11:14:10 -0800 Subject: [PATCH] [SCSI] qla2xxx: Complete mailbox command timedout to avoid initialization failures during next reset cycle. Complete the mailbox command timed out before initiating another abort cycle to recover so that mailbox commands issued during next reset cycle don't fail due to pending mailbox access timeout.
