Subject: [Bug 96921] NULL pointer dereference in lpfc_bus_reset_handler+0xd4/0x240
Date: Mon, 20 Apr 2015 15:10:30 +0000 [thread overview]
Message-ID: <bug-96921-11613-EGMFlkGafm@https.bugzilla.kernel.org/> (raw)

--- Comment #1 from James Smart <james.smart@emulex.com> ---
This is a rather old kernel, thus old driver. Lots of changes since the
driver was put out in 3.11.
I recommend pulling down the source kits for RHEL7 (3.10 kernel):
http://www.emulex.com/downloads/emulex/drivers/linux/rhel-7-centos-7/drivers/
Under FC/FCoE driver and install script - Source Driver Kit link
