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 -- james s On 4/20/2015 5:11 AM, bugzilla-daemon@bugzilla.kernel.org wrote: > https://bugzilla.kernel.org/show_bug.cgi?id=96921 > > Bug ID: 96921 > Summary: NULL pointer dereference in > lpfc_bus_reset_handler+0xd4/0x240 > Product: SCSI Drivers > Version: 2.5 > Kernel Version: 3.11.10 > Hardware: x86-64 > OS: Linux > Tree: Mainline > Status: NEW > Severity: high > Priority: P1 > Component: Other > Assignee: scsi_drivers-other@kernel-bugs.osdl.org > Reporter: joachim.reichelt@helmholtz-hzi.de > Regression: No > > Server crashed.
