Various null pointer dereference and general protection fault panics occur when there is a link bounce under load. There are a large number of "error" message 6413 indicating "bad release". The issues resolve to list corruptions due to missing or inconsistent lock protection. Lockups are due to nested locks in the unsolicited abort path. The unsolicited abort path calls the wrong abort processing routine. There was also duplicate context release while aborts were still active in the hardware. Removed duplicate locks and added lock protection around list item removal. Commonized lock handling around the abort processing routines. Prevent context release while still in ABTS list.
