The following patch series provides a partial fix for a problem seen in kdump after saving vmcore when the driver shuts down. For unknown reason the card sends a command to the driver with a random values, we can then sometimes see this - BUG: unable to handle kernel NULL pointer dereference at 00000090 .... The proper solution is to prevent this, maybe a firmware change is needed? The first patch initializes the cmd field to a dummy value so the 'ghost' command can be recognized. The second patch removes the call to the megasas_shutdown_controller in the megasas_shutdown_controller, because the errant cmd is sent while the controller is shut down and it seems to be enough to only flush cache and disable interrupts.
