If the reset is not complteted within that time frame driver will go ahead and fire cache flush and shutdown DCMDs which will end up accessing the the queues which are not initialized due to undergoing reset leads to FMU error in firmware. Fix: In shutdown function, if controller reset is not finished within 15 seconds than driver will return to the OS without firing any DCMDs.
