Problem description: Hardware could timeout Fastpath IOs one second earlier than the timeout provided by the host. For non-RAID devices, driver provides timeout value based on OS provided timeout value. Under certain scenarios, if the OS provides a timeout value of 1 second, due to above behavior hardware will timeout immediately. Fix: Increase timeout value for non-RAID fastpath IOs by 1second.
