During system shutdown or reboot, mpt3sas will reset the firmware back to ready state. However, the driver leaves running a watchdog work item intended to keep the firmware in operational state. This causes a second, unneeded reset on shutdown and moves the firmware back to operational instead of in ready state as intended. And if the mpt3sas_fwfault_debug module parameter is set, this extra reset also panics the system. mpt3sas's scsih_shutdown needs to stop the watchdog before resetting the firmware back to ready state.
