Description (partial)

Symptom:
System crashes into KDB on reboot/shutdown

Conditions:
If in the process of shutdown/reboot of  the adapter we wait for Cserver to do it, we can get an interrupt on one processor and at the same time time-out on the wait and start shutting down from Linux's end. This will lead to a race condition causing adapter structures to be freed resulting in a NULL dereference.
