There was a device discovery/fabric scan in progress. A module unload was issued which set the UNLOADING flag. As part of the discovery, after receiving an interrupt a work queue was scheduled (which involved a work to be queued). Since the UNLOADING flag is set, the work item was not allocated and the mapped memory had to be freed. The free occurred in interrupt context leading to system crash. Delay the driver unload until the fabric scan is complete to avoid the crash.
